Sieve Canister (4-pack) with Filter

Four canisters and one exterior 5-micron filter are included.

The Molecular Sieve Canisters are critical in maintaining proper performance of the QS-B220 instrument and must be replaced periodically. Manufactured in the USA, the QS-B220 Molecular Sieve Canisters have been extensively tested by the DHS Transportation Security Laboratory to ensure they meet or exceed performance standards.

Please refer to the instrument manual for installation instructions.
