Frequently Asked Questions
Are these caps sterile?
No — they are supplied non-sterile. For workflows that require sterile transport vials, a separately sourced sterile product should be used.
Do these caps come pre-assembled on the vials?
Yes, the caps are supplied pre-assembled, reducing handling steps and saving time during high-volume specimen accessioning or kit assembly.
Why choose a natural cap color?
Natural (clear/uncolored) caps are commonly used in color-coded specimen identification systems to designate a specific specimen type or transport medium, allowing staff to distinguish vials at a glance without relying solely on label reading.
Is polypropylene appropriate for specimen preservatives and transport media?
Yes — polypropylene offers excellent resistance to the aqueous buffers, dilute acids, and dilute bases found in most transport media and specimen preservatives. For samples containing high concentrations of aromatic or chlorinated solvents, compatibility should be verified prior to use.
