Hledali jste: Septum

Septa are available in a variety of materials and thicknesses. PTFE Natural 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. PTFE/High Performance Rubber is a highly pure synthetic red rubber septum that provides a reduced background level for specific GC applications, employing sensitive detectors such as ECD or NPD. PTFE/Silicone Septa (T/S) has high-quality, low background/blank value, 100% synthetic pure silicone septa.

Popis: These silicone septa with PTFE coating are suitable for VOA vials and bottles with 24-414 open-top cap.

PTFE/silicone discs, Tuf-Bond™

Dodavatel: Thermo Fisher Scientific

Popis: These discs ensure air-tight, inert seals. They are specifically designed to combine the resealability of silicone with the inertness of PTFE.

PTFE/rubber laminated discs

Dodavatel: Thermo Fisher Scientific

Popis: These discs are designed to provide a highly inert and unreactive seal. Constructed of white pharmaceutical rubber with 0,1 mm of PTFE coating bonded to one side, they are excellent for use as cap liners when a highly inert non reactive seal is desired.
