Dynarex LabChoice Cryogenic Tubes are engineered for the secure storage and transfer of biological specimens at ultra-low temperatures. Constructed from durable, laboratory-grade plastic, these tubes are built to withstand freezing conditions while maintaining sample integrity. The external threading design helps minimize contamination risks, and the screw cap with an integrated silicone gasket provides a tight, leak-resistant seal. Each tube features a self-supporting base for added stability during handling and storage. A designated white labeling area allows for clear sample identification, and bold graduation markings support accurate volume measurement.
