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. Lot-level quality controls ensure consistent vial geometry, wall thickness, and snap-cap seal integrity across every bag, supporting full traceability for CAP, CLIA, and ISO 15189 accredited laboratories. 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. Tiered volume pricing is available for institutional, biobank, and grant-funded accounts.
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.
What documentation is available for accredited laboratory compliance?
Each bag carries a lot number and manufacturing date to support traceability requirements under CAP, CLIA, and ISO 15189 quality frameworks. Contact LabSupplies.com for certificates of conformance or additional lot documentation.
