The Whitley A55 Anaerobic Workstation is the latest innovation in workstation technology from Don Whitley Scientific. Complete with two built-in, rapid airlocks and intuitive touch-screen control panel, this new workstation allows you to work completely glove AND sleeve-free.

No gloves, no sleeves, no waiting. The A55 is the first four port workstation to be offered with our new glove/sleeve-free entry system. This porthole design is ideal for users who are in and out of the chamber for short periods of time and use the workstation mainly as an anaerobic incubator. We recommend our conventional, sleeve-gassing ports for users who will be spending extended periods of time working inside the chambers. Now you can choose the entry system best suited for your workflow. The A55 offers any combination of sleeved or rapid-entry ports.

A55 Front Options

The work and storage areas of the atmosphere chamber are temperature controlled with an impressively low gradient threshold. This allows the full internal volume to be used as an incubator if desired. The A55 anaerobic chamber also offers the option of split incubation temperatures with separation between the two sides. The dual airlocks are flushed with nitrogen as an additional cost savings.

From a relatively small footprint we have been able to maximize incubating capacity to create the perfect environment, whether for a few plates or hundreds of plates. To introduce samples or equipment, the built-in, dual 12 liter rapid-cycle airlocks have the capacity to move up to 40 Petri dishes per airlock into the workstation in 60 seconds. There is also the option to specify the 15cm letterbox for rapid sample entry. As with our other Whitley Workstations, the A55 anaerobic cabinet also incorporates 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 regenerated routinely. Anotox removes the hydrogen sulfide and volatile fatty acids (by-products of anaerobe metabolism) that poison the catalyst and impede the growth of anaerobes.

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.

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.
