Catalog Number - 97020-SP

Provide secure, reliable sealing for storage applications with solid top screw caps designed for ND20 vial and bottle systems. Constructed from durable knurled polypropylene, these caps offer excellent grip and handling, ensuring consistent closure performance in both manual and high‑throughput laboratory environments. The solid top design eliminates any center opening, making these caps ideal for applications requiring complete containment.

97020-SP caps feature a 1.3 mm thick natural rubber / TFE liner with a 60 Shore A hardness, delivering a firm and resilient compression seal. The TFE layer provides chemical resistance and inertness, helping minimize interaction with stored samples, while the natural rubber backing enhances sealing strength and adaptability across different container tolerances.

These caps are designed for use with storage vials or bottles that have ND20 (20‑400) screw threads, offering dependable performance for long‑term storage and sample containment. Their solid, non‑penetrable design makes them particularly suitable for applications where injection access is not required.
