0.4 mL CryoSure® Freestanding Cryogenic Vials — PPC, Natural, 1000/Bag (220-3926-080)
These 0.4 mL CryoSure® freestanding cryogenic vials from Caplugs® Evergreen are molded from polypropylene copolymer (PPC) for reliable performance across the full cryogenic temperature range — from −80°C ultra-low temperature freezers through liquid nitrogen (LN2) and vapor-phase nitrogen storage at −196°C. The flat-bottom design stands upright on any bench surface without a rack, and each bag contains 1,000 non-sterile vials with lot-number traceability for regulated laboratory environments.

Quality & Procurement
Made in USA, these CryoSure® vials are manufactured at Caplugs® Evergreen ISO-certified facilities from virgin-grade, FDA-registered PPC resin that is BPA-free and phthalate-free. PPC construction is specifically chosen over standard PP homopolymer because it retains flexibility and crack resistance at cryogenic temperatures where homopolymer PP becomes brittle. Each 1,000-vial bag ships with lot number and manufacturing date to satisfy CAP, CLIA, and ISO 15189 traceability requirements. LabSupplies.com is an authorized Caplugs® Evergreen dealer and ships from USA inventory, ensuring consistent domestic supply without offshore lead-time risk.

Frequently Asked Questions
Are these vials sterile?
No — part number 220-3926-080 is supplied non-sterile. If your protocol requires sterile vials, contact us to inquire about sterile-format options in the CryoSure® line.
Why is PPC used instead of standard polypropylene for cryogenic vials?
Standard PP homopolymer becomes brittle below approximately −40°C and is prone to cracking under cryogenic stress. Polypropylene copolymer (PPC) maintains flexibility and impact resistance down through LN2 temperatures (−196°C), making it the preferred material for reliable long-term cryogenic storage.
Do these vials require a rack to stand upright?
No. The flat-bottom freestanding design allows the vials to stand upright on any bench surface or inside a freezer box without a specialized rack, simplifying workflow and reducing consumable costs.
Do these vials include lot traceability documentation for regulated labs?
Yes — each bag is labeled with a lot number and manufacturing date, supporting chain-of-custody documentation for CAP, CLIA, and ISO 15189 accredited laboratories.
