Tisch Scientific chromatography septa are manufactured with quality and temperature resistance in mind, some of our septa being able to withstand temperatures up to 250 degrees celsius. You can choose from a large variety of PTFE to Silicone configurations in color combinations using, red, white, blue, natural, yellow, gray, transparent, and much more.
Vials are manufactured of Clear, Type 1 Class A or Amber, Type 1 Class B borosilicate glass. Requires the use of 10-425 screw thread closures and 10mm septa. Please see Assembled Caps and Septa.
Septa can be pre-slit or not and must be selected by evaluating a few method criteria. A pre-slit septa is ideal in applications requiring drawing 20% or more of the sample volume from the vial so that suction is avoided. The slit allows ambient gas to equalize the
there was much less difference among the different septa, with the TrueView Solid, Lectrabond Solid, LCMS Pre-Split and LCMS Solid septa performing best. CONCLUSIONS An important property of a vial cap is the ability to maintain the vial analyte
Medicinal vial septa are typically compression molded out of Silicone or Butyl rubber in multi-cavity molds within a high controlled manufacturing environment. Other septum types may include a chemical barrier layer, most commonly PTFE, or in extreme case, two barrier layers.
PFTE/red rubber septa are economical for many GC applications. PTFE/silicone septa are most popular for HPLC and IC applications. Pre-slit septa are easier to pierce with thin gauge needles.
