Whitley A55 Anaerobic Workstation | Microbiology International

Whitley Workstation A55

Up to 1400 plate capacity. Two airlocks and two temperature zones.

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.

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

The Whitley A55 is available with custom port options. All four ports can be rapid entry, conventional sleeved ports or users can choose a combination of rapid entry ports and conventional sleeved ports.

Removable Front for thorough cleaning and sanitizing; enables users to introduce or remove equipment or bulk quantities of samples quickly

Options:

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.

Trolley: 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.

15cm Letterbox: Ideal for quickly introducing small quanitites of samples and supplies

Spare Cable Gland: Used to accommodate a power or data cable without affecting the chamber conditions

Data Logging: Access temperature, humidity, chamber pressure and anaerobic conditions. Stores up to 30 days of system information, accessed via USB port.

Internal Storage Trays: Maximum 2 per unit; positioned under the shelf

10 Plate Dish Rack: Easily stack and move 10 petri dishes. Prevents spills with a rigid design

Dual incubation temperatures: each side of the A55 can be set at different temperatures with separation in between the two sides.
