            Cryotubes, or cryovials, are primarily used to preserve samples stored at low temperatures, including the vapor phase of LN2. Greiner Bio-One’s Cryo.s tubes are suitable for storage down to -196 °C, ensuring consistent results and preventing sample degradation. In the event a sample shipment is necessary, Cryo.s also meet the pressure requirements for transportation by aircraft. This line of high-quality cryotubes offers several features for the identification and labeling of individual samples including colored screw caps, a white, scratch-resistant writing area, and barcoding options. White cap inserts are also available in each box of Cryo.s for labeling the top of the screw cap.
