Bi-Metal Magnetic Crimp-Top Caps with PTFE/Silicone Septa, 20 mm w/8 mm Hole, Blue/Silver, Preassembled, 1000-pk.

5 mm hole is compatible with the following systems: Carlo Erba HS500/HS800, CTC 500, Fisons HS500/HS800, and Bruker/Varian/Chrompack 9020/25. 8 mm hole is compatible with the Combi Pal. BiMetal and standard magnetic crimp-cap seals are more rigid than aluminum crimp-cap seals and require more force to seal and decap. To prevent user fatigue, Restek recommends using high-power electronic crimpers/decappers instead of manual or battery-powered crimpers/decappers when using BiMetal and standard magnetic crimp-cap seals.
