QED Scientific - Environmental Cabinets and Chambers, Incubators, Ovens and Filtered Fume Cabinets

QED Scientific was established in 1997 to supply incubators, ovens and refrigeration equipment for the UK healthcare market. Since then the company has steadily expanded, firstly to include equipment for pathology and operating theatres and then to supply environmental chambers for industry and pharmaceutical quality-control laboratories.

More recently QED Scientific has been supplying cabinets and enclosures that use carbon filters to control undesirable odours and these include everything from DNA fingerprint cabinets to standard bench fume hoods. We also offer site validation and mapping for all cabinets, both new and those already in your laboratory.

The latest addition to the QED range has been the innovative range of VarioTemp hotplates/coldplates. These are the world’s first easily portable multi workbenches and ovens for heating and cooling.

HUMIDITY AND ENVIRONMENTAL CABINETS

There are two standard ranges of environmental stability cabinet, depending on your needs. The SFC and LT base ranges are bench and floor models using ultrasonic humidity generators for optimum reliability and control.

These models also have some de-humidifying capacity to ensure that they can easily maintain the humidity and temperature environment at or below ambient room temperature. These models can be fitted with a data output for logging on your PC. Capacities are between 150L and 1,275L.

The advanced MMM range of humidity and environmental cabinets are floor-standing models and offer temperature and humidity control over a wide range. De-humidification well below ambient is standard on these as is the ability to store several ramp-and-dwell programmes that can be recalled as required. These models are all fully self-contained with water supply and drain reservoirs.

All models offered have stainless steel chambers with both humidity and temperature independently controlled by microprocessor programmers.

INCUBATORS AND OVENS

Our UK-manufactured general purpose GP incubators and ovens are available in many sizes between 10L and 6,000L so there is sure to be one that suits your needs. They can be fitted with programmers and chart recorders if required.

Whilst the incubators control over the range from 8°C above room temperature up to 100°C, the ovens have a top limit of either 250°C or 300°C. We are able to economically manufacture to user requirements and also to fit specialised ramp and dwell temperature programmers to any model.

Cooled incubators control over the range between 5°C and 50°C with an accuracy of better than 0.5°C. Capacities range from 50L to 1,275L. Two versions are available, with economy models having plastic moulded interiors and advanced models with stainless steel chambers.

The advanced CH chilled models feature Peltier environmentally friendly cooling that gives accurate cooled temperature control between 12°C and 60°C without the need for unfriendly cooling compressors. These chilled incubators are virtually silent and vibration free, so ideally lend themselves to many insect and crystal growth applications as well as general microbiology and life science uses.

FUME FILTRATION CABINETS

Many laboratories do not want fixed and ducted fume containment facilities, instead preferring to use fume cupboards with carbon filters to remove unwanted chemical odours. These Air Science fume cabinets can instead be fitted with HEPA filters if particulates are the problem that need removing. Whatever the problem, you can be assured of clean air.

All fume filtration cabinets are whisper-quiet, making them very pleasant to work with. The range includes bench and floor models as well as more specialised cabinets for the safe storage of chemicals, enclosures that protect personnel when weighing powders, and the innovative range of forensic cabinets.

DOWNFLOW CABINETS

There are occasions when a downflow bench is to be preferred. We supply either DWS self-contained bench models with carbon filters, or floor mounted and fully extracted VST models using ducts to outside the building.

As well as standard downflow cabinet models there is the ability to manufacture to user specifications. ‘Downflow’ benches are sometimes called ‘downdraft’. All are used to remove obnoxious or toxic vapours as well as particulates.

HOT AND COLD PLATES

These innovative VarioTemp hotplates and coldplates use the latest Peltier technology controlled by a digital controller. The heating / cooling area is 200mm in diameter and controls within 0.5°C between +5°C and +70°C. The specialist model has a control range from -40°C to +150°C.

All models have a super-quiet cooling fan. There are many laboratory applications for these hot and cold plate units as well as more specific applications in dentistry.

Application notes are available on request.
