Advantages of controlled rate plate freezers for labs

  • Graphic of two frozen single-use bags showing different freezing results

  • To demonstrate the effects of cryoconcentration, Naphthol Blue Black was used as a visual marker. The intensity of the blue coloration indicates the concentration of dissolved substances within the frozen solution.

    Slow uncontrolled freezing (A)

    In contrast, bags frozen in a static freezer show uneven solute distribution. Dark blue areas, especially in the lower regions of the bag, highlight significant cryoconcentration.


    Fast controlled freezing (B)

    Bags frozen using our plate-based controlled rate freezer show a uniform distribution of solutes. The result is a consistent, light-blue hue with a distinct white line through the center indicating minimal cryoconcentration.

FAQ about laboratory freezing

What are the costs for a lab freezer?

+

RoSS.pFTU lab scale is a freeze thaw unit and the perfect solution for clinical studies conducted in laboratories. The platform freezes and thaws to stable results and is therefore not comparable to a typical laboratory refrigerator, just keeping cold temperatures. We can provide costs in a quote upon request. Please also consider the possibility for lab freezer rental. 

What temperature is a lab freezer?

+

While low temperature freezers can achieve cooling temperatures in a range between around -10 and -45 °C, ultra cold freezing requires lower temperatures, between -60 and -80 °C.

What is a lab freezer?

+

Lab freezers are devices with the purpose to keep products at temperatures between 10 and -40°C. RoSS.pFTU Lab Scale is a plate based freeze-thaw unit for labs, showing perfect features for laboratory studies or cell and gene therapies.  

What is a medical freezer?

+

Medical freezers are specifically designed to store medical substances. Since these goods come with specific needs, the according devices have to meet several criteria that set them apart from ordinary household freezers.

What is the difference between a blast freezer and a plate freezer?

+

While blast freezers use cold air that is blasted on products that are yet to be frozen, plate freezers work via direct contact between the cooled plates and the products.

Is there the possibility for lab freezer rental?

+

Our lab freezer is now available for rent.  Test the freeze-thaw unit for up to three months. You will get the rent paid refunded if you decide to purchase the platform.
