Control Rate Freezer

Dohmeyer is a valued partner of universities, and medical and research institutes for development, design and manufacture of controlled rate freezers. Dohmeyer can implement complex projects, including freezing, low temperature storage systems and cryogenic pipelines.

For human and veterinarian reproduction

Liquid nitrogen plays an important role in the controlled rate freezing and cryogenic conservation of (human) cells. The cold energy and the low temperature of liquid nitrogen allow fast freezing, with minimal cell damage. Given the application of appropriate cryoprotectants, the temperature of liquid nitrogen (-195,8°C) ensures optimum conservation of tissues and cells with a maximum survival rate after thawing.

For LAB & Probiotics

Cryogenic (-80°c and lower) and deep frozen (-18°C) conservation of Lactic acid bacteria LAB) and probiot Bifidobacteria is subject to the freezing process. Control rate freezing causes minimal damage, so that the micro organisms survive the freezing process and have maximum activity.

For enzymes

For long time storage, enzymes must be kept in sterilized conditions at cryogenic temperatures, in freezers or under liquid nitrogen. To avoid protein denaturation, it is critical that samples are frozen in a controlled and quick way.
