* Temperature resistant from -40 °C up to 120 °C for NR/TEF + Butyl/PTFE resp. up to 110°C for RR/PTFE
* Natural Rubber is ideal for multiple injections due to high resealability, but not as easy to penetrate than RR/PTFE
* Butyl as a synthetic rubber has good chemical properties (cleanliness)
* Standard, moderately priced seals for GC and HPLC
* RR/PTFE has a better purity than NR/TEF, is softer and has less fragmentation,
but doesn´t offer the outstanding resealability as NR/TEF

Silicone/PTFE Seals
* Temperature resistant from -60 °C up to 200 °C
* Much cleaner than Natural Rubber, RedRubber or Butyl
* Preferably only for single injections due to low resealability properties
* Silicone liners with PTFE on both sides for less coring
* Different hardnesses (durometers) to meet requirements of the various types of needles regarding penetration
* The special, slitted liner for VWR (Merck®)/Hitachi is only available unassembled, as the diameter with the most optimal valve effect does not achieve any press-fit in the cap. Enlargement of the diameter is only possible with negative effects on the building up of vacuums in the vial
