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.

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.

When ordering the Short Path Thermal Desorption System, a wide range of systems and accessories are available depending on the application requirements of the user.

All stopcocks and movable joints in a high vacuum system must be satisfactorily lubricated, yet leak proof.

Seals are utilized in a variety of locations in the Short Path Thermal Desorption Unit.

The following glassware can be used in conjunction with the S.I.S. purge head adaptor to permit the use of the S.I.S. tube style liquid purge head for purging liquid and solid samples and trapping volatiles purged from the samples onto the S.I.S. Thermal Desorption Tubes.
