Additional Info:
Provide dependable sealing and chemical resistance with screw top caps designed for larger format storage containers and demanding laboratory applications.
98100-SP20-W caps are constructed from durable knurled polypropylene, offering improved grip and handling during routine laboratory use. The solid cap design incorporates a silicone rubber / PTFE liner, creating a flexible yet secure seal suitable for a wide range of storage and reaction environments.
The PTFE layer provides excellent chemical inertness, helping minimize interaction with stored contents, while the silicone backing ensures a reliable compression seal across varying container tolerances. These caps are compatible with 20‑400 (ND20) thread systems and are commonly used for both storage vials and heavy wall reaction vials, where durability and sealing performance are required.
