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.

Fittings to connect our 1/4" O.D. GLT desorption tubes to your particular application.

For cleaning inside Silco Coated desorption tubes

Tygon tubing is a good choice for vacuum levels down to 10-3 torr where space is limited.

In the Short Path Thermal Desorption System, the needle serves as the transfer line for sample introduction into the Gas Chromatograph from the Glass Lined Thermal Desorption Tube containing the samples being analyzed.
