Butyl/PTFE Seal
• Butyl as a synthetic rubber has good chemical properties (cleanliness).
• 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.
