Blood Plasma Freezers

BL models are our top products. Each blood plasma freezer is particularly highly insulated and offers numerous KIRSCH innovations as standard equipment. To ensure the highest possible safety and quality of our blood equipment, Kirsch is certified according to ISO 13485. This certification proves compliance with the relevant regulations for the manufacture of medical products.

Manufactured according to DIN 58375.

Our medical devices, the KIRSCH Blood Bank Refrigerators and Blood Plasma Freezers, meet all legal requirements and have been certified according to Regulation (EU) 2017/745 (MDR) since March 2022. The certification was carried out by the notified body mdc medical device certification GmbH (CE0483). 




KIRSCH is manufacturer. This enables us to develop our blood plasma freezer constantly. Each device consists of a robust housing and high quality components "Made in Germany". This guarantees reliability and a long economic life-time which in return saves your money.

blood freezer1 Temperatur
We provide blood plasma freezers with temperatures of -32°C or -41°C. 

2 Isolation
The housing is insulated with particulary good, environmentally-compatible pressure foam material to guarantee low energy consumption levels.

3 Interior Container
The interior is made of smooth aluminium with a transparent protective coating. 

4 Interior Equipment
The aluminium container features shelves mountings in which the drawers can be hanged in. The distance of these mountings can be altered in 15 mm steps (these mountings are height-adjustable). 

5 Door
The lockable door has a plastic magnetic sealing frame that is easy to replace. Door hinged on the right as standard, however this can be changed to the left at later date.


Built According to DIN 58375 Regulation

A re-circulating air cooling system is integrated as standard and reduces the physically induced temperature drop and enables an almost constant temperature to be maintained in the freezers.

Blood plasma freezers with -32 °C and -40 °C are available for plasma storage. The temperature is maintained automatically by an electronic, micro-processor controlled temperature regulator, even in the event of changing ambient temperatures. Rapid defrosting with thermal and temporal monitoring takes place automatically. The required plasma storage temperature is maintained thanks to the reversing of the refrigerant circuit.

The standard equipment features of KIRSCH blood plasma freezers include an electronic switching, monitoring and warning device, a minimum/maximum temperature memory, an RJ45 interface and a potential-free contact for connection to the central control technology.
