Security through redundant compressors
A key feature of dual-chamber freezer systems is the security of the stored materials. Should one compressor fail, a second compressor can permanently stabilise the temperature at -70°C or -80°C. This protects valuable enzymes, kits or biological reagents from an immediate temperature rise.
Applications and user groups
The devices are primarily used in research, clinical diagnostics and pharmaceutical companies. Especially for the long-term storage of tissue samples or strain collections, dual-chamber freezers offer decisive protection against sample loss in the event of technical defects.
Available device variants
Depending on requirements, different designs are available:
- Small -86°C ultra-low temperature freezers up to 130 litres
- Compact, cost-effective freezers
- Ultra-low temperature chest freezers from -86°C to -150°C
- Sanyo and Panasonic successors
- Dual-chamber freezers with frequency-controlled compressors
Frequently asked questions about dual-chamber freezers
Information on the use and technology of dual-chamber freezer systems in the laboratory.
What are dual-chamber freezers used for?
They are used for the secure storage of enzymes, kits, biological reagents as well as tissue samples and strain collections.
Which design is suitable for low volumes?
For smaller requirements, there are -86°C ultra-low temperature freezers with a volume of up to 130 litres.
What temperature is maintained in the event of a compressor failure?
Depending on the model, a second compressor can guarantee a temperature of -70°C or -80°C.
What is the advantage over standard devices?
Redundancy through two compressors offers a higher level of sample security in the event of technical failures.
For which samples is this technology particularly important?
Protection is particularly critical for irreplaceable tissue samples or strain collections established over decades.
How is the appropriate device class selected?
Selection depends on the required temperature ranges, sample volume and requirements for fail-safety.
What advantage does the system offer during a repair?
Due to the temperature maintenance of the second compressor, a repair can be prepared without time pressure.
