2.0 mL CryoSure® Round-Bottom Cryogenic Vials — PPC, Natural, 1000/Bag (220-3947-080)
These 2.0 mL CryoSure® cryogenic vials feature a round-bottom design and are constructed from polypropylene copolymer (PPC), a resin engineered to maintain flexibility and crack resistance across the full cryogenic temperature range — from −80 °C ultra-low temperature (ULT) freezers through liquid nitrogen (LN₂) storage at −196 °C. Supplied non-sterile in 1000/Bag bulk packaging, part number 220-3947-080 is well suited to high-throughput biobanking, cell line archiving, and clinical biospecimen programs that require consistent vial geometry and reliable cap seal integrity at scale. Every bag ships with lot number and manufacturing date to support CAP, CLIA, and ISO 15189 traceability requirements.

Quality & Procurement
Made in USA, these Caplugs® Evergreen CryoSure® vials are produced at ISO-certified manufacturing facilities from virgin-grade, FDA-compliant PPC resin that is BPA-free and phthalate-free. Lot-level quality controls verify consistent vial geometry, wall thickness, and cap seal integrity across every vial in the bag, providing the documentation chain needed for regulated clinical and research environments operating under CAP, CLIA, or ISO 15189 accreditation. LabSupplies.com is an authorized Caplugs® Evergreen dealer shipping from USA inventory, with tiered volume pricing available for institutional procurement and grant-funded laboratories.
Frequently Asked Questions
Are these vials rated for immersion in liquid nitrogen?
Yes — the PPC construction of these vials is rated for liquid nitrogen (LN₂) at −196 °C as well as vapor-phase nitrogen and −80 °C ULT freezer storage. PPC maintains flexibility and crack resistance at cryogenic temperatures where standard polypropylene homopolymer becomes brittle, making it the preferred material for LN₂ applications.
Are the vials sterile?
No — they are supplied non-sterile in 1000/Bag bulk packaging. For workflows requiring sterility, aseptic technique or downstream sterilization steps should be applied as appropriate for your laboratory's SOPs.
What racks are compatible with this round-bottom format?
These vials are designed for use with round-bottom vial racks. Flat-bottom rack systems are not compatible with the round-bottom geometry, so confirm your existing racking infrastructure before ordering at volume.
Does each bag include lot and date information for regulatory traceability?
Yes — every bag of 220-3947-080 is labeled with a lot number and manufacturing date, supporting the traceability documentation required for CAP-, CLIA-, and ISO 15189–accredited laboratories.
