Screw caps [for use with 2 mL vial (standard opening), thread 8-425] are available for use with sealing septa and solid caps with aluminum liners. Caps are offered in solid phenolic caps that can withstand a maximum temperature of 135 C.
Sampling vials and septa can be a source of contaminants and mistaken frequently as a fiber related problem. We recommend baking out septa at 150 °C for two hours before use and always use pre-cleaned vials for your SPME sampling. Prevent the needle from bending when doing manual SPME sampling by following this procedure:

History. Superior quality, expertly engineered Septa, caps and liners play a key role in the storage and preparation of samples. They securely seal samples from the external environment while simultaneously allowing injection by sampling needles. There are a wide array of factors that determine which septa are most suited to yo.
top polypropylene screw caps without septa are recommended instead of phenolic caps. Phenolic is a sulfur-based product that can flake and contaminate samples when syringe needle pushes through the septum. 8-425 Screw Caps with Septa (2714S29) Open top screw caps with the 8 mm septa installed.
Using bonded caps in accordance with ASTM C617 is effective when the specimen end surfaces have depressions or projections less than 1/8 in (3 mm), while unbonded cap systems in accordance with ASTM C1231 are effective with such end surface defects up to 1/5 in (5 mm). Labs, however, use either one of the methods.
Teflon PTFE/Silicone Septa: The Teflon® PTFE/Silicone septa resists coring and is recommended when multiple injections are required. This .125" septa has excellent resealing qualities. Plastisol Lined Metal Caps: Metal caps with a Plastisol liner offer excellent resistance to mild acids as in food products.
How to use Capillary Column Caps • Remove the capillary column from the GC. • Make sure the column has square cuts on both ends. • Insert the injection port end into the blue cap. • Insert the detector port end into the clear cap. The column is now ready for storage. Restek USA: 110 Benner Circle, Bellefonte, PA 16823
the process flow.
