PTFE/Red Rubber (red) Septa with Aluminum Cap Crimp Top Pre-Assembled Kit PerkinElmer Each product is manufactured using strict quality control standards resulting in consistent cap dimensions with septa which may be certified for higher purity grades.
Ivory PTFE/Red Rubber Septa: (C4020-34) PTFE/Red Rubber Septa offer good solvent resistance, good resealing characteristics and resistant to coring. They are an economical choice where a PTFE barrier is desired. The recommended operating temperature range for this septum is –40 to 100°C PTFE White Silicone PurePakTM Septa: (C4020-32)
PTFE/natural red rubber PTFE/natural red rubber are moderately priced seals for GC and HPLC with good chemical properties. They are ideal for multiple injections due to high resealability, but not as easy to penetrate as PTFE/RR. Natural rubber septa are offered assembled into aluminum crimp seals. PTFE/synthetic red rubber septa: (PTFE/RR)
