86°C Freezer
Ultra-low temperature freezer maintaining -86°C for long-term storage of biological samples, cell lines, and temperature-sensitive research materials.
The 86°C Freezer provides ultra-low temperature storage for biological samples, reagents, and temperature-sensitive materials requiring preservation at subzero temperatures. This upright freezer unit maintains consistent -86°C operation for long-term storage of proteins, enzymes, cell lines, tissue samples, and other biological specimens that require preservation below standard freezer temperatures.
The compact design with 82.0 cm length, 46.5 cm width, and 45.5 cm height provides laboratory-grade freezing capacity while maintaining a manageable footprint for research facilities. The unit supports biobanking protocols, sample archival workflows, and research applications requiring stable ultra-low temperature conditions for specimen integrity maintenance.
How It Works
Ultra-low temperature freezers operate using cascade refrigeration systems that achieve temperatures significantly below conventional freezing. The primary cooling cycle uses a standard refrigerant to pre-cool the system, while a secondary refrigeration circuit employs specialized refrigerants capable of reaching -86°C operating temperatures. This two-stage approach allows efficient heat removal from the storage chamber while maintaining temperature uniformity.
Temperature control systems monitor chamber conditions continuously, adjusting compressor operation to maintain setpoint stability. Insulation systems minimize heat transfer from ambient conditions, while door seals and cabinet construction prevent temperature fluctuations during access cycles. The freezer maintains consistent ultra-low temperatures necessary for preserving biological sample integrity over extended storage periods.

Practical Tips
Verify temperature accuracy using calibrated external monitoring devices at multiple chamber locations before loading valuable samples.
Why: Temperature uniformity confirmation ensures consistent storage conditions throughout the chamber volume.
Clean condenser coils monthly and inspect door seals regularly for proper closure and insulation integrity.
Why: Regular maintenance prevents temperature fluctuations and reduces energy consumption while extending equipment lifespan.
Pre-cool sample containers and organize loading procedures to minimize door opening duration during sample placement.
Why: Reduced thermal cycling protects sample integrity and maintains chamber temperature stability.
Use insulated gloves and safety equipment when handling materials at ultra-low temperatures to prevent cold injury.
Why: Direct contact with -86°C surfaces or samples can cause immediate tissue damage and cold burns.
Maintain continuous temperature logging and establish alarm systems for temperature excursion detection.
Why: Documentation of storage conditions supports sample integrity verification and regulatory compliance requirements.
Monitor frost accumulation patterns and address excessive ice buildup through proper door seal maintenance.
Why: Ice accumulation indicates air infiltration that compromises temperature stability and increases energy consumption.
