Bigneat is an innovator in the design of Ductless Fume Cabinets, utilising carbon and HEPA filtration technology. Ductless Fume Hoods are suitable as alternatives or can be used in addition to Fume Cupboards for many laboratory procedures. In many situations where fume cupboard space is at a premium, a recirculatory filtration cabinet can be used to make a laboratory procedure safe, reducing the risk of release of fumes, vapours and particulates into the laboratory environment.
