J&K Scientific's crimp caps with PTFE/silicone septum are made of high-quality aluminum and can withstand temperatures up to 180°C and pressures of 600kPa, with safety release when pressure exceeds 45 psi. Compatible with 20 mm sample vials, these caps create a secure seal to ensure that they stay on and the integrity of the vial's contents remain intact during volatile sample analysis. These caps are compatible with CTC Combi PAL (Varian, Gerstel, Shimadzu, ATAS), HP, Perkin Elmer, and Agilent and are suitable for a wide range of chromatography analysis methods. The centre opening has a diameter of 10mm to allow sample needles to penetrate the chemically resistant silicone septum without damage. These caps come packaged in a plastic pouch for cleanliness, as well as a box to ensure that they arrive undamaged.
