86℃ Freezer(Undercounter Type) 90L
Compact 90-liter ultra-low temperature freezer maintaining -86°C for cryogenic sample storage in space-constrained laboratory environments.
| Automation Level | manual |
The 86℃ Freezer (Undercounter Type) 90L provides ultra-low temperature storage in a compact undercounter format suitable for laboratory environments with limited floor space. This freezer maintains consistent temperatures at -86°C, enabling long-term preservation of temperature-sensitive biological samples, reagents, and research materials. The 90-liter capacity accommodates standard laboratory storage containers while fitting beneath standard laboratory benches.
The undercounter design maximizes laboratory workflow efficiency by positioning frequently accessed samples at ergonomic heights. Temperature uniformity and stability are critical for maintaining sample integrity during extended storage periods, supporting research protocols that require cryogenic preservation without the footprint of full-size ultra-low freezers.
How It Works
Ultra-low temperature freezers achieve -86°C operation through a cascade refrigeration system utilizing multiple refrigerants and compression stages. The primary refrigerant circuit pre-cools the sample chamber, while a secondary ultra-low temperature circuit provides the final cooling to reach -86°C. Insulation systems minimize heat transfer from the ambient environment to maintain temperature stability.
Temperature control systems monitor and regulate cooling cycles to prevent temperature excursions that could compromise sample integrity. The undercounter design incorporates specialized insulation and door sealing systems to minimize cold air loss during access cycles while maintaining consistent internal temperatures throughout the storage volume.

Practical Tips
Allow adequate clearance around ventilation areas to ensure proper heat dissipation and optimal cooling performance.
Why: Restricted airflow can lead to compressor strain and temperature instability.
Clean condenser coils regularly to maintain cooling efficiency and prevent system overload.
Why: Dust accumulation reduces heat transfer efficiency and increases energy consumption.
Verify temperature accuracy using calibrated reference thermometers at multiple locations within the storage volume.
Why: Temperature gradients can exist within freezers, affecting sample preservation uniformity.
Ensure proper electrical grounding and use dedicated circuits to prevent electrical hazards during operation.
Why: High-current draw of ultra-low freezers requires appropriate electrical safety measures.
Document temperature records and any excursions to maintain sample integrity documentation for regulatory compliance.
Why: Temperature history is critical for validating sample quality in regulated research environments.
Monitor door seal integrity regularly and replace gaskets if cold air loss is detected.
Why: Compromised door seals lead to temperature instability and increased energy consumption.
Organize samples systematically with clear labeling to minimize door-open time during sample retrieval.
Why: Extended door opening causes temperature fluctuations that can compromise sample integrity.
