Catalog Number - 97040-10C-S

Provide secure, non‑penetrable sealing for EPA style vials with solid top screw caps engineered for storage and transportation applications. Constructed from durable knurled polypropylene, these caps offer dependable grip and ease of handling in both manual and high‑throughput laboratory environments. The solid top design ensures a completely closed system, preventing contamination and evaporation during storage or shipment.

97040-10C-S caps feature EPA quality silicone rubber / PTFE liners with a 45 Shore A hardness and a thickness of 3.2 mm, delivering a reliable compression seal for long‑term storage and EPA testing workflows. The PTFE layer provides excellent chemical inertness, minimizing interaction with stored samples, while the silicone backing ensures flexibility and consistent sealing across vial tolerances.

These caps are compatible with 30 mL, 40 mL, and 60 mL EPA style vials with ND24 (24‑400) threads, making them a versatile solution for laboratories requiring secure sealing across multiple vial sizes. The solid top construction makes them ideal for applications where injection access is not required.
