Bigneat has announced the addition of Controlled Atmosphere Storage (CAS) Cupboards to its range of safety cabinets.

For many years Bigneat has been producing ventilated carbon filtration cabinets which are typically used for storage of bottles of chemicals. The ventilation provided removes vapours from drips remaining on the bottles and the carbon professional filter absorbs potentially hazardous chemicals and odours.

Bigneat's cupboards enable laboratory staff to store compounds conveniently and safely, close at hand within the laboratory.

Bigneat's new cupboard now opens up the uses for localised storage. With a dry nitrogen gas environment, dry specimens and moisture sensitive compounds can also be stored locally.

This moisture-free environment is maintained using dry nitrogen gas and detection monitor the need for gas flow within the cabinet.

The cupboard shown is a nitrogen storage system with 100% professional seal integrity, which provides a dry, oxygen-free atmosphere. Incorporated within the cabinet is carbon filtration for the removal of DMSO vapours or other residual solvent vapours.
