1.5 mL CryoSure® Freestanding Cryogenic Vials — PPC, Natural, 1000/Bag (220-3902-080)
These 1.5 mL CryoSure® freestanding flat-bottom cryogenic vials from Caplugs® Evergreen are constructed from polypropylene copolymer (PPC) — a material specifically chosen for its flexibility and crack resistance at temperatures down to -196°C in liquid nitrogen. Supplied non-sterile in 1000/Bag bulk packaging, part number 220-3902-080 is engineered for demanding cryogenic workflows including biobanking, cell line storage, and long-term biospecimen archiving. The flat-bottom design allows each vial to stand upright on the bench without a rack, streamlining sample handling during both storage setup and retrieval.

Quality & Procurement
Made in USA, these CryoSure® vials are produced at Caplugs® Evergreen ISO-certified facilities using virgin-grade, FDA-registered PPC resin that is BPA-free and phthalate-free. PPC offers a meaningful performance advantage over standard PP homopolymer for cryogenic applications: while homopolymer PP becomes brittle below approximately -40°C, PPC retains flexibility and crack resistance through the full range from -80°C ULT storage to -196°C liquid nitrogen immersion. Each bag ships with lot number and manufacturing date documentation, supporting full chain-of-custody traceability for CAP-, CLIA-, and ISO 15189-accredited laboratories. LabSupplies.com is an authorized Caplugs® Evergreen dealer and ships from domestic USA inventory, minimizing lead-time risk and supporting continuity of supply for high-volume institutional purchasing programs.
Frequently Asked Questions
Are these vials suitable for direct liquid nitrogen immersion?
Yes. The PPC construction is rated for the full cryogenic range including liquid nitrogen (LN2) at -196°C, vapor-phase nitrogen storage, and -80°C ULT freezers. PPC maintains flexibility at these temperatures, unlike standard polypropylene homopolymer, which can become brittle and crack below -40°C.
Do these vials come sterile?
No — they are supplied non-sterile. For most biobanking, genomic, and cryopreservation workflows the vials are used with sterile technique or filled inside a biosafety cabinet, making non-sterile bulk packaging the practical and cost-effective choice for high-throughput labs.
Can these vials stand upright without a rack?
Yes. The flat-bottom freestanding design allows each vial to stand independently on any level surface, which simplifies bench-top sample labeling, filling, and retrieval without requiring a dedicated rack.
What documentation is included for regulated laboratories?
Each bag includes a lot number and manufacturing date, providing the traceability chain required by CAP, CLIA, and ISO 15189 accreditation standards. Contact LabSupplies.com for certificate of conformance or additional quality documentation if required by your accreditation body.
