Material & Chemical Resistance
Polypropylene copolymer (PPC) offers excellent resistance to aqueous buffers, dilute acids and bases, and many common alcohols, making it well suited to the broad range of specimens and preservatives encountered in laboratory settings. PPC can be autoclaved, providing flexibility when sterile closures are required after initial supply. As with all polypropylene-based materials, prolonged exposure to chlorinated solvents, aromatic hydrocarbons, and strong oxidizing acids should be avoided.

Frequently Asked Questions
Are these screw caps sterile?
No — they are supplied non-sterile in 72/Bag bulk packaging. However, because they are molded from polypropylene copolymer, they can be autoclaved if sterile closures are needed for a specific application.
How do I confirm these caps will fit my specimen containers?
These caps are designed for wide-mouth containers with a 90 mm diameter threaded opening. Verify that your container's neck finish matches the 90 mm thread diameter before ordering; consulting your container manufacturer's specifications is recommended.
What is the advantage of the green color?
The green color supports color-coded laboratory workflows, allowing staff to quickly distinguish cap types, container groups, or sample categories at a glance, which helps reduce handling errors in busy clinical and research environments.
