3.5 mL CryoSure® Freestanding Cryogenic Vials — Polypropylene Copolymer, Natural, 1000/Bag (220-3905-080)
The Caplugs® Evergreen CryoSure® line delivers a 3.5 mL freestanding, flat-bottom cryogenic vial molded from polypropylene copolymer (PPC) — a material specifically chosen for its flexibility and crack resistance at temperatures down to -196°C liquid nitrogen. Supplied non-sterile in sealed 1000/Bag packaging, these vials are engineered for long-term biospecimen storage across the full cryogenic spectrum, from -80°C ultra-low temperature freezers through liquid nitrogen and vapor-phase nitrogen systems. The flat-bottom design allows upright, rack-free placement directly on the bench or in a freezer box, simplifying workflows in high-throughput biobanking and clinical laboratories.

Quality & Procurement
Made in USA, these CryoSure® vials are produced at Caplugs® Evergreen ISO-certified manufacturing facilities using virgin-grade PPC resin that is BPA-free and phthalate-free. LabSupplies.com is an authorized Caplugs® Evergreen dealer shipping from domestic USA inventory, so procurement teams avoid the extended lead times associated with offshore sources.
Frequently Asked Questions
Are these vials rated for immersion in liquid nitrogen?
Yes — the PPC construction is rated for liquid nitrogen storage at -196°C as well as vapor-phase nitrogen and -80°C ultra-low temperature freezers. Unlike standard polypropylene homopolymer, PPC retains flexibility and resists cracking at these extreme temperatures.
Do these vials require a rack, or can they stand upright on their own?
The flat-bottom freestanding design allows the vials to stand upright without a rack on the benchtop or inside freezer boxes, streamlining sample sorting and retrieval in high-throughput workflows.
Are the vials sterile?
No — they are supplied non-sterile. The sealed 1000/Bag packaging maintains cleanliness from warehouse receipt through point-of-use, and the vials are manufactured from virgin-grade, BPA-free PPC resin. Laboratories requiring sterility should validate a suitable decontamination or sterilization step for their specific workflow.
