8mm Combination Seal, NR/TEF, RR/PTFE, 100 pcs/pack
PP Screw Seals ND8: Natural Rubber/TEF, RedRubber/PTFE Seals
Natural Rubber is ideal for multiple injections due to high resealability, but not as easy to penetrate as RR/PTFE.
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 same resealability as NR/TEF.
Temperature resistant from -40°C up to 120°C for NR/TEF + Butyl/PTFE resp. up to 110°C for RR/PTFE.
