PTFE-fused septa are suitable to overcome the degradation, which happens due to prolonged high temperatures, commonly observed in silicone rubber septa. The degradation results in baseline drift and additional peaks. It is generally fixed with the PTFE face towards the column packing. Synonyms: …

Screw caps are available as solid caps with aluminum liner. Caps are made from phenolic resin. Solid phenolic caps can withstand a maximum temperature of 205 C.

Vial septa are available in a variety of materials. Septa, tan PTFE/silicone (diam. x thickness 8 mm x 1.5 mm) are sized to fit screw top vials. They are suitable for use with most organics (until pierced) and are not recommended for use with chlorosilanes.

Application: Glass screw top vials (40 ml) sealed with phenolic open-top caps and PTFE/silicone septa may be used to contain pectin or plant material, during d2H analysis of plant methoxyl groups, in an experimental study to analyse stable hydrogen-isotope of methyl chloride, which is emitted from…
