Cryopreservation

We offer a professional freezing system for storing cell materials and their components at temperatures of up to -196°C. With a wide range of highly transparent CryoPure tubes, we cover a volume range of 1.2 ml to 5 ml. Cryo boxes for deep-freeze storage and stands for easy handling of the CryoPure tubes complete the range.

    Where should the CryoPure tubes in the nitrogen tank be stored – in the liquid phase or in the gas phase?

    Because from -130°C no further biochemical reactions occur in the cells, storing these in the gas phase (< -130°C) is entirely sufficient for successful cryopreservation. We therefore recommend that CryoPure tubes are stored in the gas phase. Please note the safety advice included with our products.
