Don Whitley Scientific Whitley A85TG and A95TG anaerobic workstations

The Whitley A85TG and A95TG workstations are anaerobic chambers which run from three separate gases. This is claimed to make them 30% cheaper to operate than dual-gas versions, which use cylinders of ANO₂ and N₂. The units run on separate cylinders of N₂, H₂ and CO₂ to create anaerobic conditions, which is said to be more cost-effective than purchasing premixed anaerobic gas.

Both models are fitted with a large 30 L airlock with a powered internal door to provide effective sample and equipment transfer in the fastest possible time, while ensuring the minimum amount of oxygen is introduced into the chamber.

Manual, oval glove ports enable the user to work gloved or bare-handed. Each glove port also acts as a mini-airlock for 10 plates so users can transfer up to 20 plates as they insert their arms. This further saves gas as it avoids the need to run an airlock cycle for small numbers of plates.

A colour, touch-screen control panel provides ease of use and visual display of parameters such as temperature, humidity and airlock cycle status. An automatic commissioning cycle and a built-in dehumidification system save time and resources.

A range of options and accessories is available to tailor the workstation to the user’s specific application, including a fully integrated anaerobic conditions monitor that displays real-time oxygen levels and enables download of data for further analysis.

The A85TG can accommodate 500-700 x 90 mm Petri dishes. The larger A95TG accommodates 1000-1400 x 90 mm dishes in a chamber that has two sets of glove ports.
