Product Description
Glue from a bonded liner can leach into samples, especially after repeated autoclaving. These polypropylene caps avoid that problem with a liner that is welded in place, giving a clean, chemically resistant seal that holds up cycle after cycle in the autoclave.
This listing is for Kimble catalog number 73808-28400: Black Polypropylene Screw Thread Cap, Welded PTFE-Faced Silicone Liner, 28-400, Case of 48. The solid-top caps are molded from black polypropylene and fitted with a PTFE-faced white silicone liner welded to the cap. The PTFE face resists chemical attack, and the silicone backing provides resilient sealing. Threads include 13-415, 15-415, 24-400, 24-410 and 28-400 to fit culture tubes, vials and bottles. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
