Bigneat ventilated chemical storage cupboards and shelving systems offer protection to laboratory staff from hazardous fumes, aerosols, vapours or gases. Chemicals are retained in the carbon filter and clean air is returned back to the laboratory. The smaller CS 812 and CS 822 are open style shelves designed to be situated close to where you are work – your chemicals will be within reach and convenient - and the larger CS 834 and CS 844 provide a long-term storage option.
