Designed for safe storage of cells or biological fluids in the vapor phase of liquid nitrogen or any mechanical freezer. Ideal for sperm, serum or blood specimens, micro- biological cultures, cell cultures, and hazardous or valuable samples.
The rugged, proprietary copolymer and uniform wall construction will stand up to any current microcentrifuge. Plus, tubes' external threads prevent leaking even under the pressure changes of air transport. No tube offers more security to your sample!
