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. Furthermore, these caps can be color-coded to denote the contents inside, making it easier to differentiate between different types of samples. Phenolic caps are an ideal solution for securely storing and transporting materials, providing a reliable seal that keeps the contents safe from contamination. They are commonly used in laboratories and research institutions as well as in commercial settings such as pharmaceutical production. With their durability and dependability, phenolic caps provide a reliable and economical solution for any container that requires secure sealing.

By using these types of caps with screw thread vials, you can ensure your contents are safe from contamination and securely stored during transport or storage. With a range of sizes available to fit all applications, these caps provide a reliable and cost-effective solution to your containment needs.
