ESTS Logiclave

Established in 2003 with the vision of becoming the manufacturer that best provides innovative and high quality autoclaves in the UK - ESTS are a Northamptonshire based service provider and manufacturer of autoclaves and steam sterilizers ranging from 100 to 6000Litre capacity for the healthcare, research and scientific laboratory sectors.

Our standard range of high quality autoclaves include:

  • Logiclave LAB Freestanding Autoclaves (100 to 300L)
  • Logicalve Laboratory Autoclaves (300 to 6000L)
  • Logiclave Clinical / Porous Load Sterilsers (600 / 800L)


Freestanding Autoclaves

Our range of freestanding autoclaves available in standard cylindrical and rectangular chamber sizes from 100 to 300 litres capacity and intended to suit a wide variety of modern laboratory applications.

This range compliments our current range of large capacity rectangular section autoclaves and utilises the same proven and easy to use Logiclave control system.

Nominal Chamber Sizes (Cylindrical Vessels):

  • 100 Litres - 500mm Diameter x 500mm Deep
  • 145 Litres - 500mm Diameter x 750mm Deep
  • 200 Litres - 500mm Diameter x 1000mm Deep

Nominal Chamber Sizes (Rectangular Vessels):

  • 150 Litres - 600mm High x 500mm Wide x 500mm Deep
  • 225 Litres - 600mm High x 500mm Wide x 750mm Deep
  • 300 Litres - 600mm High x 500mm Wide x 1000mm Deep

Overall Nominal Dimensions (HWD):

  • Single Door Logiclave   - 1900 x 730 x 1350mm
  • Double Door Logiclave - 1900 x 730 x 1310mm

Where required, the autoclave can be provided with a fully integrated high efficiency steam generator.

The ‘on demand’ steam generation system incorporates an exceptionally low water content heat exchanger, PID controller and a fully automatic blow-down system.  It requires very low maintenance and there is no requirement for independent boiler insurance inspections.

Laboratory Autoclaves

Our Logiclave Laboratory Autoclave is intended for processing a wide range of materials found in today’s modern laboratory environment including :

  • Sealed culture media
  • Unsealed culture media
  • Fluids
  • Plastic and mixed discards
  • Fabrics
  • Glassware
  • Equipment
  • Utensils

The chamber, jacket and doors are manufactured from minimum 6mm thick high grade 316L stainless steel for maximum corrosion resistance.

Other process contact materials are generally of conventional copper and brass construction although where appropriate, hygienic stainless steel is also used.

Each stage of the vessel manufacturing process is witnessed and certified by an independent Insurance Company who also verifies the materials used, welder qualifications, weld procedures and acceptance of hydrostatic pressure test.

The autoclave control system is based on the following hardware components:

  • Rugged industrial PLC type controller
  • Analogue input module
  • Temperature input modules
  • Digital input modules
  • Digital output modules
  • Full colour operator interface (Touch sensitive screen)
  • Independent data recorder (Where specified)

The control system software has been specifically developed for the precision control of the autoclave process.

Program configuration, initiation and monitoring of the process are all possible through the ergonomically designed operator interface.

Autoclave Refurbishment

An autoclave represents a major capital investment with a projected lifespan of typically 10 to 15 years under normal operating conditions.

The autoclave chamber is a very large part of this financial investment. Where the autoclave or sterilizer chamber remains in an acceptable condition after this time, it is very often the control system that becomes obsolete and fails.

In these instances it can be economical to consider updating the autoclave control system. ESTS offers the Logiclave type control system upgrade package that can be very easily installed and programmed to suit any autoclave.

Refurbished and upgraded autoclaves from ESTS offer excellent value for money and will save considerable sums over the cost of brand new autoclaves.

ESTS are always conscious of the clients own financial constraints and with this in mind works with the client to deliver a package that meets their expectations both in terms of technical performance and within budget.

Refurbishments are carried out either onsite or back at our workshops

Autoclave & Sterilizer Instrument Calibration

For the continued performance of your autoclave within its specified parameters, routine calibration of its temperature and pressure measuring and recording instruments is a vitally important part of laboratory and production quality assurance.

We offer a full instrument loop calibration service where each sensor is removed from the autoclave and subjected to a range of known reference temperatures / pressures.  Measured values from the autoclave sensors are documented against UKAS certified references as found.  Should the measured values be found to fall outside the specified limits of accuracy the technician will make the necessary adjustments and repeat the procedure fully documenting all ‘as left’ results.

During periodic testing, the calibration of all instrumentation is checked against UKAS certified reference sources by inserting calibrated thermocouples and pressure transmitters adjacent to the autoclave control probes.  The autoclave is then operated through a normal process cycle and any errors apparent with calibration will be corrected by our technician.

Our calibration service includes the autoclave control system, chart recorders, paperless graphical recorders and pressure gauges.

Autoclave Insurance Inspections

The Pressure Systems Safety Regulations 2000 cover the legal obligations of owners, users and others concerned with the installation and use of pressure systems.  The regulations apply to all systems that include pressure vessels and contain gas or liquefied gas at a pressure in excess of 0.5 bar above atmospheric pressure and steam at any pressure.
To comply with Regulation 8, the user must ensure a Written Scheme of Examination is in place for any system with a pressure vessel containing steam or having a pressure x volume product in excess of 250 bar litres.  Further, Regulation 9 requires that a competent person examine the parts of the pressure system included in the scheme of examination within the intervals specified in the scheme.  The competent person will decide on the maximum interval between examinations under the Written Scheme.  As a guide, earlier legislation set out maximum examination intervals for specific types of equipment.  Typically, for steam plant an interval of 14 months was specified.  For steam receivers the examination period was generally in the range 26 - 38 months.

The examinations are usually carried out by your insurance company or other nominated ‘competent person’.  ESTS can help you meet your legal obligations as an autoclave owner / user by providing experienced technicians to disassemble and prepare the equipment for its examination, carry out hydrostatic pressure tests and return the autoclave to service on completion.

Autoclave Maintenance & Service Contracts

Nationwide service for most types of autoclave from all manufacturers

As the owner or user of an autoclave it is your responsibility to ensure a schedule of servicing and periodic testing is in place.  All our service contracts include regular service visits where our technicians will inspect, lubricate, adjust and repair or replace worn consumable components.  On completion of the work, our technician provides a written report of the work carried out and details of any defects or faulty components requiring further attention.

Service Contracts

Our flexible approach to service contracts means we work with our customers to develop a service agreement that satisfies all their requirements.  All our autoclave service contracts include a structured planned preventative schedule.
