Technical Narrative
The Caplugs® Evergreen 222-3003-085 is a 2.5 mL PPC Transport Vial with Natural Cap, sterile, 25/Bag Unassembled. Transport vials are designed for short-term specimen transport and ambient or refrigerator-temperature storage — distinguished from cryogenic vials (optimized for —80°C/LN2) by their transport-focused geometry and cap design. The 2.5 mL PPC vial provides a small-volume sterile container for micro-volume specimen aliquots, reagent preparation, and point-of-care specimen collection where a compact sterile screw-cap vial is the required container.
Polypropylene Copolymer (PPC): full organic solvent and fixative compatibility, improved cold-temperature flexibility, optical clarity for visual inspection. Sterile, individually shipped in bag with cap unassembled. BPA-free, phthalate-free, FDA-compliant,
Procurement economics: $118.48/Bag, $4.7390/vial. LabSupplies.com ships from USA inventory, typically same business day.

Clinical & Research Laboratory Applications
Caplugs® Evergreen 2.5 mL PPC transport vials serve clinical diagnostics, reference laboratories, and pharmaceutical settings requiring a compact sterile screw-cap vial for micro-volume specimen transport and short-term storage. The 2.5 mL format is suited to micro-volume blood, urine, and body fluid aliquots collected for analytical sub-fractionation — smaller than the standard 15 mL or 50 mL conical but larger than standard microcentrifuge tubes, bridging the gap for protocols requiring 2–3 mL working volumes in a sterile, leak-resistant screw-cap container. PPC provides optical clarity for visual content inspection, chemical resistance for standard transport media and preservatives, and cold-temperature flexibility for refrigerator storage and transport on ice.

Frequently Asked Questions
Are the transport vials sterile?
Yes. Sterile — packed 25/Bag, unassembled (vial + cap in same bag).
How does a transport vial differ from a cryogenic vial?
Transport vials are designed for short-term specimen transport and refrigerator-temperature storage at ambient or 2–8°C — optimized for sealing reliability and chemical compatibility with transport media. Cryogenic vials (e.g., CryoSure® series) are engineered for long-term storage at —80°C through liquid nitrogen (—196°C), with PPC formulations specifically selected for cryogenic-temperature flexibility. Select transport vials for point-to-lab specimen transport; select cryogenic vials for long-term frozen bioarchiving.
Is the 2.5 mL transport vial compatible with standard transport media?
Yes. PPC is compatible with standard clinical specimen transport media including Amies transport medium, Stuart's medium, Universal Transport Medium (UTM), and viral transport medium (VTM). PPC is also compatible with standard preservatives (sodium fluoride, EDTA, boric acid) used in urine transport vials. Verify specific transport medium compatibility with your laboratory SOP before standardizing.
