Lab Unlimited UK

The Carl Stuart Group was founded in 1984 by Stuart and Gillian Smith. From a small beginning our business has grown to encompass many services and products, covering different market sectors and geographical regions. The focus of our business, however, remains the same. We are a customer orientated company and strive to meet and exceed your expectations in everything we do.

As our portfolio grew we decided to present and promote our product and technical service offerings under distinct brands.  The Laboratory instrumentation, consumables and technical & integration services are promoted under Lab Unlimited.

The Lab Unlimited product portfolio offers laboratory/analytical products from more than four hundred leading manufacturers. A substantial part of this offering is published on this very site. We also produce a printed catalogue that can be requested by emailing us.

Smart Syringe Pump (Model: ESP-124) QTY 1 Features: * Performs key operations like diluting and mixing samplesupto 1:25, filtering, storing and replacing withdrawn samples with fresh media * The glass or Teflon syringes eliminate adsorption and offer a high accuracy of dosing (better than +1%) * No routine calibration or maintenance * Supports 10 ml and 25 ml syringes * The high suction capability enables efficient use of fineinline filters (0.45 microns), eliminating manual filtration process * The 4-way motorized valve offers unprecedented syste flexibility and the capability to deal with sticky media * The ergonomically designed Syringe Pump has a very small footprint to save bench space 8. Dx Sample collector Model : (ESC-12Dx). * Stirring Facility in Sample collector We are offering stirring mechanism in the sample collector. Many times, it is noticed that when diligent is mixed with the elicoat , proper dilution is not achieved. For this, Electrolab has developed stirring mechanism in sample collector, which ensures, proper stirring and helping achieving desired dilution Eliminates waste volume by returning programmable rinse media back to the vessel. * Loop Back Facility Loop back system is a system for avoiding carry over and to achieve correct replenishment, this facility can be offered only because , we are offering Lx series machine. In conventional auto sampling system, this facility is not offered. * Post filtration with 0.45 Micron or 0.22 Micron (Customers need to procure filters locally) US Pharmacopea, has suggested use of 0.45 micron filters for proper filtering. In post filtration , we have offered manifold, on which,0.45 micron filters can be installed by Customer and proper filtering , as per USP, is achieved. If this would have not been their, Chemist had to take sample out from sample collector and do filtration separately. That function now is been done in sample collector only. * Visual indication for Sample Collector (Please refer features) Features * The x-y arm movement meets all the automated sampling requirements such as collecting , mixing, aspirating and diluting the samples * The diving mechanism pierces the septas(precut) of vials to prevent evaporation losses * Special sensor detects the alignment and type of tray used to prevent any human errors * Completely covered to prevent contamination and air drafts which cause excess evaporation of the collected samples * Ergonomically designed to save space * Easy removal of waste tray * Visual indication for Sample Collector Status: * Connected * Run * Error Adapts 4 types of trays Glass tubes (a) 25 ml (16 x 8) (b) 10 ml (24 x 8) (optional) HPLC vials 1.5 ml (24 x 8) (optional) 1.5 ml dilution possible (12 x 8) (optional) Combination tray (a) 8 x 8 HPLC vials & Glass tube combination (b) 8 x 8 HPLC vials (1.5 ml) (c) 8 x 8 Glass tubes (25 ml) Customized trays available 9.
