Product Description
Scintillation and sample vials need a cap that seals tightly and keeps solvents from contacting the liner rubber. These white urea screw caps pair a rigid shell with a PTFE-faced, foam-backed liner that compresses for a reliable seal during storage.
This listing is for Kimble catalog number 73802U-8425: White Urea Screwcap, 8-425, Case of 432. Caps are molded from urea and fitted with a PTFE-faced foam-backed rubber liner. The PTFE face provides chemical resistance, while the foam backing conforms to the vial lip. Threads range from 8-425 to 24-400, and caps are packed 432 per case. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
