Small -86°C ultra-low temperature freezers: selection and technical specifications

Small ULT freezers up to 130 liters cover applications where a large-volume floor-standing unit would be oversized: decentralised sample storage at the workstation, primary supply for small working groups, or as a supplement to existing cooling infrastructure. Under-bench models can be integrated under laboratory tables, saving floor space without compromising cooling performance.

Technical specifications of available models

The smallest models in the range start at 7 liters (ULUF 15, temperature range -40°C to -90°C) and 35 liters (Fryka B 35-85 freezer box with digital display and recorder output, natural refrigerants). The under-bench compact freezers from Axofreeze and Midea range from 75 to 128 liters: power consumption 3.3 to 3.9 kWh/day at -75°C, noise levels 45 to 47 dB(A), capacity 45 to 90 cryoboxes in 2-inch format. The Fryka TS 80-100 (100 liters) holds up to 81 cryoboxes at 4.3 kWh/day and under 49 dB(A) — also available with an integrated data logger.

When a small ULT freezer is the right choice

Small -86°C ultra-low temperature freezers are particularly suitable for molecular biology laboratories with manageable sample volumes, for core facilities as decentralised dispensing and receiving stations, and for pharmaceutical companies storing temperature-critical substances directly at the processing site. Under-bench models are also a practical solution in cleanrooms or GMP areas where floor space is regulatorily limited. For temperature monitoring, models with an integrated data logger or retrofitting with a WLAN data logger with alarm forwarding are recommended.
