Flask 2 Flask 3


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. Silco Coated Thermal Desorption Tubes. The following glassware all have 24/40 ground glass necks. The PTFE Purge Head Adaptor seals into this ground glass fitting and its 1/4" diameter 'O' Ring seal accepts the Tube Style Liquid Purge Head. This Tube Style Purge Head described previously permits both the introduction of the purge gas to purge the volatiles from the sample and the trapping of these volatiles on the desorption tubes.
