The A35 is the first workstation to be offered with our new glove/sleeveless system. Sample manipulation within a secure anaerobic environment is now as easy as working aerobically on the laboratory bench. The working and storage areas of the chamber are temperature controlled with an impressively low gradient throughout. This allows the full internal volume to be used as an incubator if desired.

Another major advantage of the sleeveless system is that it uses eight times less gas when entering the workstation compared with a conventional porthole system. The airlock is flushed with nitrogen as an additional cost-saving.

To introduce samples or equipment, the built-in, 12 liter, rapid-cycle airlock has the capacity to introduce up to 40 Petri dishes into the workstation in 60 seconds. There is also the option to specify the 15cm letterbox, ideal for quickly transferring all sizes of dishes and small items.

Whatever your application, we can tailor the Whitley A35 Workstation to your requirements. For example, if you want to be able to use electrical equipment inside the chamber, you could include the option of a built-in, interior electrical socket. If you require the ability to thoroughly sanitize your workstation between experiments or need to introduce large items of equipment, you may want to specify the removable front option.

A35 Front Options

From a relatively small footprint we have been able to maximize incubation capacity to create the perfect environment, whether for a few plates or hundreds of plates.

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.
