  • Controlled rate freezer for cryopreservation with RoSS.LN2F

    The left-side graph illustrates the outcomes of a controlled freeze run with RoSS.LN2F conducted at a cooling rate of -1.15°C/min​. Employing a controlled freezing rate leads to markedly enhanced cell viability and recovery compared to uncontrolled freezing. 

    • Cooling/freezing rates in bags are adjustable from 1k/min to 23k/min (chamber temperature)
    • Starting from LPTF (last point to freeze) to -170°C
    • Fast cooling of chamber and subsequent continuous LN2 injection (makes system controllable and economically in operations)
    • Adjustable phase transition time for higher product safety

Controlled rate freezing of cells

Along with autoclaves, centrifuges, laboratory freezers, incubators, refrigerators and ultra-low temperature freezers (ult freezers), cryostorage and (consequently) cryogenic freezers have become indispensable as lab equipment for many researchers, healthcare providers and drug product manufacturers.

Liquid nitrogen freezers like the RoSS.LN2F are used when stem cells, gene therapies, cell culture microplates or several reagents and new products need to be prepared for long-term storage under cryogenic temperatures.

Sample storage of a few vials or pipettes is equally important as storing greater amounts of biologics by the means of a -170°C cryogenic freezer.

Not only for shippers, storage capacity in liquid nitrogen storage is essential, since cost effectiveness and high efficiency are necessary to be achieved. Furthermore, user-friendliness in terms of easy access or intuitive operation via touch screen are also factors to be considered when choosing the right cryogenic freezing device.

FAQ about cryogenic freezing

What is a cryogenic freezer?

+

A cryogenic freezer is a device that is made to freeze goods like certain biological down to extremely low – cryogenic – temperatures. Often, liquid nitrogen is used to achieve temperatures lower than -150°C and to cryogenically freeze goods.

How much does a cryogenic freezer cost?

+

Although the price range for cryogenic freezers is wide, one can state that they are usually more expensive than regular freezers (that cannot achieve these low temperatures), given the fact that cryopreservation is a highly complex procedure. Therefore, several safety mechanisms need to be in place, as well as measures that must be taken to avoid contamination.
