Options and Specs Images and Video

The Whitley Workstation A95 has a 1090 plate capacity and is constructed of rigid acrylic (6mm thick front panels, 10mm thick side panels). The panels are chloroform annealed, creating a uni-body construction capable of withstanding positive pressure well in excess of the 4 PSI maintained constantly by the system.

Patented use of “oval” shaped gloveless entry ports allow the introduction of samples/materials by acting as a transfer airlock. This process allows the user to place their materials in the chamber while placing their hands in the chamber, reducing overall gas consumption considerably by not having to run a secondary airlock cycle.

Patented use of Anotox (activated carbon impregnated with ferric hydroxide) for atmospheric conditioning. By using Anotox, the catalyst does not have to be removed and baked routinely. Anotox removes the Hydrogen Sulfide and volatile fatty acids (by-products of anaerobe metabolism) that poison the catalyst and can impede the growth of anaerobes.

The entire workstation is temperature controlled, allowing for temperatures between 4°C and 44°C. There is no need for extra incubators and loss of space efficiency. Humidity is controlled automatically by an electronically controlled water removal system. Water is pumped to a container containing a silver-impregnated bacteriostatic wick to evaporate the water externally. There are no containers to empty. The humidity setting is user programmable. The electronics and lighting are located in an external control housing. There is no need to compromise the workstation to change light bulbs or perform fuse replacement.

The 100 plate airlock is an option to either the Whitley Workstation A95. The airlock cycle is electronically controlled and requires only a press of a button to operate. Catalyst dedicated to the airlock is housed internally and does not need to be changed or replaced. The system uses a radio controlled footswitch to eliminate clumsy wiring. There is a manual override for use when necessary. There are audible alarms to notify the user of low gas pressure, gas leaks, or power failure. The system is capable of maintaining anaerobiosis in the event of power loss for up to 24 hours.

Tangential fans create laminar flow in chamber, internal atmosphere is constantly being circulated over catalyst, Anotox, and heating mat for a consistent and strictly anaerobic environment
Double internal power socket available, 2 Amp max
Customized trolley hardware available, makes moving the workstation easy and fast.
Gas requirements: 1 x ANO2 = 10% H2, 10% CO2, 80% N2 -OR- 1 x ANO2 and Nitrogen
No requirement to bake catalyst, simply replace catalyst and Anotox annually


Anaerobic Conditions
Monitoring System
This factory-fitted option monitors and displays real time oxygen levels within the workstation. Depending on the percentage of oxygen present, the chamber/airlock symbol on the touch screen will read green, yellow or red. The electronic Anaerobic Conditions Monitoring System is complete with oxygen sensor and a special software package. The oxygen sensor is located inside the chamber for accurate, real-time readings. The sensor is easily and quickly calibrated via the touch screen.

Our custom-designed trolley frees up bench space and allows the chamber to be moved. The trolleys are built with high quality tubular steel and smooth rolling lockable wheels. They offer a sturdy and stable frame to support your use of our anaerobic and microaerophilic workstations.

Gas Pressure Monitor
Designed as a method of monitoring the gas supply. The system will indicate the status of both sides of the switchover: FULL – IN SERVICE, and DEPLETED. When a cylinder or cylinder bank is depleted, the green light will change to a red light, and the audible alarm will sound.
