  1. Total Algae Sensor: Monitor Harmful Algal Blooms
    3 September 2018

    Harmful algal blooms (or HABs) are becoming more frequent, intense, and are now seen by many as a public threat. For this reason, now more than ever, water quality monitors and managers need reliable tools that can help them monitor, reduce, and manage the impacts of harmful algal blooms.

    Why is the Total Algae Sensor (TAL) from YSI the Right Tool to Fight Harmful Algal Blooms?

    They help with early detection by allowing easy collection of data on blue-green algae for data analysis with consideration of weather conditions as well as other important parameters.

    Built for the field, this sensor features welded titanium construction and military-specification connectors which are ideal for rugged conditions. Similar to other smart sensors, the TAL sensor has onboard memory, processing, and allows for sensor-zeroing to be performed on-site.

    Main Features:

    Detect the onset of an algae bloom as early as possible to plan your response
    Support a rational approach for the collection of samples for other laboratory analyses, saving you time and money
    Understand the seasonal and weather-related patterns of algae growth in your system
    Understand the relevance of other parameters like pH, dissolved oxygen, and temperature

    There are two sensors available:

    The Total Algae-Phycoerythrin (TAL-PE) for saltwater, used for monitoring marine cyanobacteria and the Total Algae-Phycocyanin (TAL-PC) a dual-channel fluorescence-based sensor, perfect for monitoring freshwater cyanobacteria. Bot are ideal for early detection of blue-green algae that could lead to harmful algal blooms.

    The Total Algae sensor is ideal for applications like beach monitoring, vertical or horizontal profiling, and source water monitoring for potentially toxic algae – especially when paired with the ProDSS multiparamter system or the EXO sondes.

  5. Neodisher® LaboClean FLA Changes Formula
    27 August 2018

    Dr Weigert, leading company in professional systematic hygiene solutions, have announced a change in the formula of their popular special cleaner Neodisher® LaboClean FLA.

    The company has stated that the change was due to the discontinuation of a component by their supplier, which forced a slight adjustment to the formula of the detergent. 

    In a statement issued by the company, they state that "the complexing agent contained in the product was replaced by an equivalent alternative. The type of cleaning agent of the neodisher® LaboClean FLA and its characteristic features, application properties, as well as used concentration, remains unchanged. The equivalency of the formula was verified, evaluated and consequently, its conformance determined.”

    This change in the formula will be taking place from December 2018.

  6. Pipetting: Are you Doing it Wrong?
    27 August 2018

    The experts at BioSistemika know that inconsistent pipetting can interfere with your application results and even cause experimental failure. 

    To make sure your pipetting technique is spot on, they have put together 12 simple tips you can follow to improve your pipetting technique!

    1. Pre-Wet the Pipette Tip
    Evaporation in the tip can cause sample loss before delivery, so make sure to aspirate and expel any samples at least 3 times. This increases humidity in the tip and reduces sample evaporation.

    2. Immerse Tip in the Proper Depth When Aspirating
    Too little immersion can lead to air aspiration where too much immersion can cause samples to cling to the outside of the tip. Aim for immersing the tip below the meniscus.

    3. Pause After Aspiration
    After the plunger stops the liquid in the tip might still be moving, so leaving the tip in the liquid for about one second after aspirating the sample will help keep the volume of sample correct.

    4. Keep Plunger Pressure & Speed Consistent
    The better consistency you achieve while aspirating and dispensing – applying the same force and speed – the better, more repeatable your results will be.

    5. Take the Pipette Straight out
    Always hold the pipette vertically, as holding the pipette at an angle or touching the sides of the container might alter the volume of the sample.

    6. Check the Tip Before Dispensing
    Gently remove any droplets from the outside of the tip, avoiding the tip opening, as absorbent material can draw sample out of the tip.

    7. Check the Tip After Dispensing
    Remove the tip after dispensing, while pressing the second stop of the plunger to avoid sample re-aspiration. Also, dispensing the sample with the tip touching the side of the container helps delivering any residual sample in the tip.

    8. Standard Mode Pipetting
    With aqueous samples, choose “standard” over “reverse” pipetting mode, as in reverse mode the pipette tends to deliver more than the calibrated volume.

    9. The Right Pipette
    The volume range in the pipette is everything. The closer it is to the volume of your sample, the more accurate your results will be.

    10. The Right Tip
    Make sure the tips are high quality with airtight seal to minimize pipetting force and are free of moulding defects. However, the most important thing to consider is that mismatched tips and pipettes can result in inaccuracy, imprecision, or both.

    11. Ambient Temperature Balance
    Try to reach a temperature balance between the liquid and the equipment. Working at a single, constant temperature improves overall precision, as it helps to minimise variations in air pressure, relative humidity and vapor pressure of the liquid.

    12. Keep Pipette Handling to a Minimum
    Always wear gloves when pipetting to reduce heat transfer, put it in the stand or set it on the bench when not in use and avoid handling pipette tips or containers of samples yet to be pipetted.

  7. IDS Go Wireless: No more Wet Feet in the Field
    20 August 2018

    The new waterproof bonding on the IDS probes is what makes them perfect for outdoor measurements and your greatest ally in the field. According to WTW, come July 2018, the new modules will be labelled with an IP 66 rating (hose-proof).

    One of the applications where these will prove to be more helpful is groundwater pumping testing. A classical pumping test includes the measurement of pH, conductivity, dissolved oxygen (DO), and maybe Oxidation Reduction Potential (ORP). The groundwater is pumped through a flow-through vessel equipped with the appropriate sensors which are connected to the meter(s) – any of the Multiline®IDS Portable Meters will do perfectly.

    What’s the big advantage?

    Ease of use, convenience, accurate results, no cables & no wet feet! When using tethered sensors, the operator would have to wait near the measuring spot until stable results were achieved – which can be hard sometimes, depending on the weather and field conditions. 

    Now, using the IDS probes there’s no need for that! The sensors communicate with the meter, via wireless, without any problems or cable hassle. Plus, the measured values can be read in real time from a dry shelter close by or even a car.

    Download the WTW IDS probes brochure, or check out the portable meters we have available on our website:

  8. How Do You Communicate with Your Alicat Device?
    20 August 2018

    Alicat flow meters or pressure controllers output a large amount of data that can be useful in multiple ways. The most elementary way of communication would be through the LCD panel on the front of the device. Here you can choose to display different scientific parameters like: unit ID, absolute pressure, temperature, volumetric flow, mass flow, set point and gas type. 

    However more advanced communication features are also available like internet protocols, ethernet-based protocols, RS232, RS45, Modbus RTU, Modbus TCP/IP, DeviceNet, Profibus, EtherCAT, and analog signals like 4-20mA, 0-10 volt, or 0-5 volt.

    Depending on your application it is important to choose the ideal form of communication and interaction with the instrument. According to Alicat, before deciding on which protocol to use, the customer needs to be mindful of the existing set up. “For example, a small laboratory starting from scratch interested in getting the experiment up and running quickly would be best served using RS232 connected to a computer. Even more simply, they could use the six buttons on the front panel, right out of the box. However, if a large factory is integrating an Alicat into a system with potentially hundreds of other existing devices on a common network, we can usually accommodate the protocol that allows the device to integrate into the factory’s system.”

    Supported Protocols:

    RS232 is the most feature-rich way to digitally communicate with 
    your Alicat devices, (through a standard DB9 cable);

    RS485 if you need to run a line for thousands of feet.

    Internet protocols, ethernet-based protocols, Modbus RTU, Modbus TCP/IP, DeviceNet, Profibus, EtherCAT (to communicate with other equipment and/or networks);

    Analog signals like 4-20mA, 0-10 volt or 0-5 volt (to accommodate legacy systems);

    Alicat has engineered a multi-drop version of their communication language that allows up to 26 devices to talk on the same RS232 network in parallel. “By assigning each with a letter of the alphabet, the named instruments will only respond when they are addressed by their corresponding letter.”

  11. How to Take Care of Your New EXO Sonde?
    20 August 2018

    Your EXO multiparameter water quality sonde is very rugged and strong-built to withstand the harshest weather conditions, however, there are some recommended practices to keep your system functioning properly for years to come.

    What about Wear and Tear?

    Severe wear on any one part of the sonde's body can lead to water intrusion which can potentially lead to costly repairs and faulty data. One of the things you can do to prevent excessive damage is using a probe and sonde protective sleeve which protects the sonde's body and bulkhead. This combined with good maintenance practices and easy handling of the sonde - so they don't get beat up too much-, will keep the body and bulkhead tube in good shape.

    Mind Your Wetmate Connectors!

    The Wetmate connectors on the top of the battery compartment and in the bulkhead, and sensors have to be properly maintained. A very costly repair, these are mostly damaged by lack of lubricant in the sensor's wetmate and usually leads to a pin being galvanic oxided off the sensor. What can you do to prevent some of the issues? Never introduce any foreign objects into a female connector and only use only Krytox grease to lubricate the mating surfaces of the connectors. 

    Be Careful with Batteries!

    When a battery leaks acid it can lead to the loss of all the electronics and sensors in your sonde. Never store batteries in the sonde for an extended period and always check your batteries before each deployment. Please note that battery life is reduced in cold water applications and is heavily dependent on sensor configuration.

    When using alkaline batteries, the estimated battery life is approximately 90 days for EXO2, and 60 days for EXO3, at 20°C with a 15-minute logging interval, with temperature/conductivity, pH/ORP, Optical DO, turbidity, and Total Algae-PC sensors installed along with a central wiper.

    Also, keep in mind that when using rechargeable nickel metal hydride (NiMH) batteries, the estimated battery life is not always the same, as they vary in manufacturer capacity and discharge curves. YSI recommends a NiMH D-cell battery with a minimum rating of 10,000 milliamp hours, fully charged each time it is used.

  12. 10 Critical Facts about Carbon Monoxide
    13 August 2018

    The experts at Analox – leading company in custom gas detection solutions – have created a list of the top ten most essential facts about Carbon Monoxide (CO) that you must know.

    It is important to understand that CO is an odour & colourless gas that is found naturally in the atmosphere and that exists at around 0.2 parts per million (ppm), which is considered the safe level for humans. However, with the ever more intense industrial activity in the world, CO is reaching unsafe levels. 

    Show me the Facts!

    - At a concentration of 12,800 ppm, CO will cause someone to collapse, lose consciousness, and death is likely to occur in just one to three minutes

    - In 2015, 53 people died in the UK from accidental carbon monoxide poisoning

    - Carbon monoxide is the most common type of indoor air poisoning, in countries where they still rely on fires to heat homes and cook food

    - The most common source of human-produced CO is formed during combustion, when there is not enough oxygen available to produce carbon dioxide

    - CO gets into the bloodstream and prevents it from carrying oxygen to the cells and vital organs of the body

    - CO is known as the ‘silent killer’ because it has no taste, no smell and you can’t see it

    - Open fires, boilers and cookers all produce carbon monoxide

    - Carbon monoxide leaves the body quickly, so taking immediate action such as turning off an appliance, opening windows and leaving the area in the case of a suspected leak could save your life.

    And a Bit of Trivia

    - Cats can sense a carbon monoxide leak and are known to refuse to come into the house – this is a good, but not to be relied upon, warning sign

    - The phrase, ‘canary in a coal mine’ came about because miners used to take birds into mines to act as a warning signal for dangerous gases like carbon monoxide

    Nowadays, many companies and organisations are making a great effort to monitor and control CO levels with a carbon monoxide gas detector. Browse our blog for more information:

    10 Critical Facts about Carbon Monoxide
  13. Anglian Water Optimizes Water Treatment with THM Analyzer
    13 August 2018

    Parker Hannifin released an application note regarding how their Trihalomethane (THM) Analyzer was able to help Anglian Water - largest water company in England and Wales – to optimize their processes.

    In the paper, you can read how THM analysis can be quite costly and time consuming. It involves prepping the samples, sending them to the laboratory and waiting for the results. This approach means that the analysis data cannot be used for real time process control which can lead to harmful consequences in water safety. For companies and plants that are dealing with public water safety, such as Anglian Water, this called for a new strategy: the THM Analyzer.

    The THM Analyzer provides rapid measurement of THMs in water. It is a time and cost saving solution for a water plant or facility, as it ensures safe drinking water without tedious sample preparation, allowing the analysis to be made on-site and within 30 minutes.

    These features certainly appealed to Anglian Water when they started looking for an alternative to traditional THM analysis.

    So, as we can read in the application note, when Anglian Water decided to change its strategy regarding their water treatment and supply processes, they installed a THM Analyzer. With this new approach, the company managed to improve their sampling processes by making them more time and cost efficient.

    In the paper, you can also read what Mark Berry, Innovation Project Manager, at Anglian Water had to say regarding the The Parker THM Analyzer:

    “Using the Parker THM analyser we are now able to measure THM concentrations inhouse, and in less than 30 minutes. We are currently analysing over 20 samples a week and have found the system to be very easy to use. Aside from the potential cost-saving benefits, the much faster analysis capabilities provide scope for further improvements in operational efficiency.”

  14. Get Trihalomethane Measurements in 30 minutes
    13 August 2018

    The THM Analyzer is vital for drinking water safety and compliance. It can, in a matter of minutes, display the Trihalomethane concentration in water, thus making sure that the water is suitable and safe for drinking.

    Designed with the expertise from Water Industry end users and specialists, the Parker THM Analyzer is a cost effective approach to the monitorization of water disinfection by-products.

    Why is it SO Unique?

    The THM Analyzer performs a 30 minute analysis, without the need for tedious sample preparation, right at your plant or facility. With an integrated purge and trap gas chromatograph system, it will help to optimise water treatment, evaluate water age and ultimately improve your control over the formation of THMs.

    It also comes with a powerful software which provides better understanding and use of THM measurements and data analysis. The status panel operator interface is very intuitive and user-friendly. It displays measurement progress during an analysis cycle and then displays the measured concentration levels for individual and total THM.

    Also, Parker’s THM Analyzer is fully portable. Its rugged, light and compact design allows him to be easily moved and carried around (carrying case available).

    What's the difference between the On-line and the benchtop THM Analyzer?

    The on-line version does not require operator interaction. Once set up, regular sample analysis will occur automatically regardless of where the analyzer is installed.

    The Parker on-line THM Analyzer features a more robust enclosure to allow installation right at the process or distribution point of interest. Through SCADA interaction (Supervisory control and data acquisition) the operator can remotely, and safely, determine when and how often the analysis is performed.

    How does it Work?

    The THM analyser is quite simple to use and does not require any expensive and time consuming sample preparation or off-site analysis.
    Simply collect a sample and connect it to the analyzer sparging system. Push the start button to begin the measurement cycle and you will see the individual and total THM information displayed clearly on the touchscreen and laptop display. 

    Not only do you get access to the THM concentration information, but you will be able to view other analytical results as well. Such as measured concentration and detailed chromatography data which are automatically archived for future review. 
    You can also transfer the data to other software packages for more detailed trending analysis of THM information.

    This application note about Anglian Water and the Parker Hannifin’s fast drinking water analyzer is a great example of how the THM can help optimise water treatment.

    Does it suit my Application?

    The Trihalomethane Analyzer can be used in many places where THM water testing is key, e.g., Local Water Plants, Universities, Beverage Plants, amongst others.

  15. YSI’s 8 steps to Calibrate & Measure Ammonia ISEs in the Lab
    13 August 2018

    Are you required to calibrate & measure Ammonia ISEs in the Lab? According to YSI, there are 8 easy but sensitive steps you must follow, to obtain repeatable and reliable results.

    Step #1: Connect the ammonia electrode to a meter that has a BNC input and can show ion concentration directly. Also, make sure to set up the instrument to measure ammonia.

    Step #2: Connect a temperature sensor to the instrument. This is key as effective ion concentration measuring depends greatly on temperature. The standard solutions temperature as close as possible to the expected sample.

    Step #3: Prepare the standards. Standards should bracket the expected sample range. There should be a tenfold difference in concentration between the high and low standards. Make sure standards are in date and use a minimum of two standards. You can also use a third standard if there is more than a tenfold difference. 

    Step #4: Place the electrode in the lowest concentration standard and stir at a constant rate using a stir bar and stir plate. The stirring speed should be limited to minimize loss of ammonia gas. Use the same stirring rate when calibrating and measuring samples.

    Step #5: Add your ionic strength adjustor (ISA) to the standard and start calibration. Once the ISA is added, the solution should have a pale blue colour, indication the pH.
    Allow the solution to stir for 1 minute and begin calibration. This is a delicate and time sensitive process. Ammonia in the sample will no longer be sufficient 4 minutes after ISA is added, so after this time, a fresh standard will need to be prepared.

    Step #6: Calibrate with additional standards. 
    Once the instrument has accepted the first calibration point, finish calibrating using steps #4 and #5 for the remaining calibration points. Make sure to calibrate in order of increasing concentration.
    If calibrating with less than 7 standards, you can finish calibration process after calibration using the highest concentration standard.

    Step #7: Evaluate electrode slope on the calibration record. For highest accuracy, the ammonia electrode slope should be between -53 mV/decade and -65 mV/decade. If not, recalibration is required.

    Step #8: Recalibration is KEY! The ammonia electrode should be calibrated at the beginning of each day. Verify the calibration result every 2 hours by preparing a fresh low to mid-range standard, adding ISA, and verifying the reading.

  16. New version of the ISO 9001:2015 Standard for Carl Stuart Group
    13 August 2018

    After successfully maintaining our ISO 9001 certification for over 20 years, we continue to evolve our systems in alignment with developments of this standard. Therefore, we are proud to say that the Carl Stuart Group have now been certified to the latest version of this standard: the ISO 9001:2015.

    What is different?

    According to ISO, the International Organization for Standardization, the biggest change from ISO 9001:2008 to ISO 9001:2015 is its new structure. ISO 9001:2015 now follows the same overall structure as other ISO management system standards (known as the High-Level Structure), making it easier for companies like us to maintain two distinct management systems supporting our ISO 9001 & ISO 17025 accreditations. There is a new focus on the identification and mitigation of risks within our business, and equally so on opportunities that we are presented with. 

    Quality is at the heart of our operations, the re-certification process for the new standard has provided us with a more user-friendly QMS, with a deeper management input throughout OUR organisation. Achieving this new standard has allowed us the opportunity to review and streamline many of our existing process. It is helping to ensure our operations, services and knowledge management capabilities are fully aligned to the needs and expectations of our customers.

  22. Top 5 factors for choosing the right disposable glove
    16 September 2016

    The HSE issued guidelines to help employers select the right type of protective glove for their particular situation.  They realise that considering all possible implications in the decision can be a daunting task, and so they have provided 5 main factors that all employers should consider when choosing the right type of protective glove:

    1. Identify the substances handled
    2. Identify all other hazards
    3. Consider the type and duration of contact
    4. Consider the user - size and comfort
    5. Consider the task


    Check out the full HSE guidelines Choosing the right gloves to protect skin to get the questions you need to answer before searching for the right type of disposable glove for you.

    At Lab Unlimited we know that each of the above factors can greatly influence the type of glove you need. And that's why we supply a wide range of disposable Nitrile Gloves to help you match the glove to your needs.
