The LFS-113 provides for constant flows between 5 to 200 mL/min at variable back pressures up to 25" of H2O for use in pumping air or gas samples through the S.I.S. Short Path Thermal Desorption Sampling Tubes.

After conditioning and sample loading, the ends of the tubes are fitted with stainless steel caps with seals to maintain the integrity of the medium and sample.

For loading small samples into Silco Coated desorption tubes

The top fitting of both purge heads consists of a 1/16" fitting for the attachment of the sparging needle followed by needle adaptor to seal the needle in place and provide for the attachment of the purging gas line.
