2.5 mL Sterile PPC Transport Vials with Screw Caps, Natural — 25/Bag (222-3003-085)
These 2.5 mL polypropylene copolymer (PPC) transport vials provide a compact, sterile screw-cap container for micro-volume specimen transport, point-of-care collection, and short-term storage at ambient or refrigerated temperatures. Supplied 25 per bag with caps unassembled, they are distinguished from cryogenic vials by their transport-focused geometry and leak-resistant screw cap design. The natural PPC construction offers excellent optical clarity for visual content inspection and broad chemical compatibility across clinical and research matrices.

Frequently Asked Questions
Are these vials sterile?
Yes — the vials are supplied sterile, 25 per bag, with caps shipped unassembled. Assemble the cap just prior to use to maintain sterility of the vial interior.
Are these suitable for cryogenic storage at –80°C or in liquid nitrogen?
These are transport vials optimized for specimen transport and short-term storage at ambient or refrigerated temperatures. They are not described as cryogenic vials, so they should not be assumed suitable for –80°C or liquid nitrogen applications without independent validation.
Why choose PPC over standard polypropylene for transport vials?
Polypropylene copolymer (PPC) offers improved cold-temperature flexibility compared with standard PP, along with excellent optical clarity for visual inspection and broad compatibility with organic solvents, fixatives such as 10% NBF, and cryoprotectants such as DMSO — making it well suited to a wide range of clinical and research specimen types.
Can these vials be used for reagent preparation involving organic solvents?
Yes. PPC is compatible with methanol, acetonitrile, DMSO at typical laboratory concentrations, and formalin-based fixatives, making these vials appropriate for small-scale reagent preparation as well as specimen handling workflows.
