Frequently Asked Questions
Are these vials shipped sterile and ready to use?
Yes. Each 3.5 mL CryoSure® vial is supplied sterile. The vials and natural screw caps ship unassembled, so caps are threaded on at the point of use to maintain a controlled sealing torque.
What temperature range do these cryogenic vials tolerate?
Molded from polypropylene copolymer (PPC), these vials are designed for cryogenic storage and withstand ultra-low freezer and nitrogen-phase temperatures. Confirm vapor- versus liquid-phase suitability against your facility's storage protocol.
Do the vials stand upright without a rack?
Yes. The freestanding base lets each vial stand on its own for fast, hands-free filling and capping, reducing the need for additional support racks during processing.
How many vials are in each pack?
Each pack contains 25 vials per bag (25/Bag), supplied unassembled with natural screw caps. The list price shown is per pack.
