FAQs
What are these 1.2 mL cryogenic vials used for?
These vials are designed for long-term cryogenic storage of biological samples such as cells, tissues, and molecular biology specimens. Their durable USP VI-grade polypropylene construction and sterile, contamination-free design make them ideal for biobanking, clinical archiving, and research workflows requiring reliable preservation at extremely low temperatures.
How does the internal-thread design benefit cryogenic storage?
The internal-thread closure improves sealing security by reducing the risk of cap loosening during freezing and thawing cycles. This design provides a tighter seal, protects sample integrity in ultra-low temperatures, and minimizes contamination risk, making it ideal for sensitive biological materials and long-term cold storage environments.
Are these cryogenic vials sterile and contamination-free?
Yes, each vial is E-beam sterilized and certified non-pyrogenic, DNase-free, RNase-free, and human DNA–free. This ensures suitability for highly sensitive workflows, including molecular biology, clinical research, and long-term biobanking. Their sterile status helps maintain sample purity from initial handling through extended cryogenic storage periods.
Can these vials be autoclaved for reuse?
These vials are autoclavable at 121°C and 15 psi, allowing laboratories to sterilize them before use when needed. Their polypropylene structure withstands high temperatures without warping. However, most labs use cryovials as single-use consumables to ensure optimal sample integrity and prevent cross-contamination between experiments or stored specimens.
How should these cryogenic vials be stored for best performance?
They are recommended for storage in the gas phase of liquid nitrogen tanks. This prevents liquid nitrogen from entering the vial, which could expand upon warming and compromise sample integrity or safety. Gas-phase storage ensures stable ultra-low temperatures while maintaining secure, contamination-free conditions for biological materials.
