Safe sample storage in standard freezers down to -86°C
Selecting the appropriate standard freezer is crucial for the long-term integrity of biological materials. In laboratories and clinics, -86°C ultra-low temperature freezers are primarily used to ensure a constant temperature environment. The range includes various designs, from compact benchtop units to large-volume upright units, tailored to specific space constraints and capacity needs in research.
Designs and technical variants
Within this category, you will find specialised solutions such as small -86°C ultra-low temperature freezers up to 130 litres, which are ideal for decentralised storage or limited floor space. Dual cooling systems with frequency-controlled compressors ensure increased reliability and energy efficiency. This technology dynamically adjusts cooling performance to demand, which is particularly advantageous during frequent door openings. Additionally, Sanyo and Panasonic successor models are offered, continuing established standards in deep-freeze technology.
Ultra-low temperature chest freezers for extreme temperature ranges
Complementing the upright models, the portfolio includes -86°C to -150°C ultra-low temperature chest freezers. This design offers physical advantages regarding temperature stability, as cold air escapes less when the lid is opened. -150°C ultra-low temperature chest freezers are a relevant alternative for cryopreservation without liquid nitrogen in cell biology and tissue archiving. Compact, cost-effective freezers also allow for an entry into professional ultra-low temperature cooling with an optimised budget.
Frequently asked questions about standard freezers
Here you will find answers to important aspects regarding the selection and operation of ultra-low temperature equipment.
What are standard freezers used for in the laboratory?
These devices are used for the long-term storage of samples such as DNA, RNA, proteins, cell cultures, or clinical samples at temperatures of -86°C to almost completely stop biological processes.
Which capacity is suitable for small laboratories?
For laboratories with low sample volumes or limited space, small -86°C ultra-low temperature freezers up to 130 litres are suitable, providing professional cooling performance in a compact footprint.
What role does temperature stability play at -86°C?
Precise temperature control is essential to ensure the vitality of cells and the stability of reagents. Devices with frequency-controlled compressors support particularly constant thermal conditions.
What is the difference between ultra-low temperature freezers and chest freezers?
Upright freezers offer quick access and better organisation through shelving systems, while chest freezers often provide even more stable temperature distribution and lower cold loss when opened due to their design.
What are the advantages of dual cooling systems?
Dual cooling systems feature two independent cooling circuits. In the event of a failure in one circuit, the second can often maintain the system at a critical low temperature to prevent sample loss.
How do I find the right model for my requirements?
Selection should be based on the required storage volume, available laboratory space, and the desired temperature range (down to -86°C or -150°C). Professional advice assists with technical configuration.
What should be considered when installing ultra-low temperature equipment?
Important factors include sufficient ventilation for the compressor unit, a stable power supply, and regular inspection of door seals to avoid ice formation and unnecessary energy consumption.
