Caps, Screw Top, Solid, with Natural Silicone Rubber / Natural PTFE Liner, fitted in knurled polypropylene, White Caps. For use with 24-414mm threaded EPA Style vials. ND24 threads. BASIK Brand. 100/PK.
Additional Info:
Provide reliable, long‑term sealing for EPA style vials with solid top screw caps designed specifically for storage and transport applications. These caps are constructed from durable knurled polypropylene, offering improved grip and ease of handling in both manual and high‑throughput laboratory environments. The solid top design ensures a fully closed system with no opening, making them ideal for secure containment.
97041-SP24 caps feature a 3.18 mm (0.125″) thick silicone rubber / PTFE liner, delivering a strong compression seal and excellent chemical resistance. The PTFE layer provides inertness to minimize interaction with stored samples, while the silicone backing ensures flexibility and consistent sealing across varying vial tolerances. These caps are designed for long‑term storage and are compatible with 30 mL, 40 mL, and 60 mL EPA style vials using ND24 (24‑414) threads.
Because the cap has no center hole, it is specifically intended for storage and transportation rather than autosampler injection. This makes it a dependable solution for laboratories requiring secure sealing and protection of samples during storage or shipment.
