4mL cryotubes, or cryovials, with external thread 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 that sample shipment is necessary, Cryo.s™ also meet the pressure requirements for transportation by aircraft.
The portfolio of Cryo.s™ tubes includes 4mL cryotubes with different base formats as well as several cap colors. These high-quality cryotubes offer 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.
