Caps, Screw Top, with Natural Silicone Rubber / PTFE Septa, fitted in knurled polypropylene, Black Caps. For use with 24-414mm threaded EPA Style vials. BASIK Brand. 100/PK.
Additional Info:
Provide reliable sealing and consistent injection performance with screw top caps designed specifically for EPA style vial workflows. Constructed from durable knurled polypropylene, these caps offer improved grip and handling during both manual and automated laboratory processes. The combination of silicone rubber and PTFE septa ensures a balance of flexibility, durability, and chemical resistance for a wide range of applications.
97040-05C-K caps are equipped with EPA quality silicone rubber / PTFE septa, suitable for both EPA testing and long‑term storage applications. The 12.5 mm center hole allows accurate and repeatable needle penetration, making these caps ideal for autosampler use while maintaining надежное sealing. The PTFE layer provides chemical inertness, while the silicone backing supports resealability during repeated injections.
These caps are compatible with 30 mL, 40 mL, and 60 mL EPA style vials using ND24 (24‑414) threads, making them versatile across multiple vial sizes and laboratory workflows. They are well suited for environmental testing, analytical applications, and sample storage environments requiring dependable sealing and performance.
