Choose from a variety of caps from phenolic caps to urea caps.

Phenolic caps are a type of closure designed to be used with screw thread vials. They typically have a F-217 liner along the inner diameter for extra sealing power, and come with cone liners that keep contents within the container. These caps provide an effective seal, making them suitable for storing liquids or powders in laboratory environments. Phenolic caps are an ideal solution for securely storing and transporting materials, providing a reliable seal that keeps the contents safe from contamination. 

With a range of sizes available to fit all applications, these caps provide a reliable and cost-effective solution to your containment needs.
