86℃ Freezer BDF-86V158 (Customized)
Ultra-low temperature freezer providing -86°C storage for long-term biological sample preservation and cryopreservation protocols in research laboratories.
| Automation Level | semi-automated |
The BDF-86V158 Ultra-Low Temperature Freezer provides -86°C storage capacity for long-term preservation of biological samples, reagents, and temperature-sensitive materials in research laboratories. This customized unit features precise temperature control and monitoring systems designed to maintain stable ultra-low temperatures required for cryopreservation protocols and biobanking applications.
The freezer incorporates advanced insulation technology and refrigeration systems to achieve and maintain temperatures suitable for preserving enzyme activity, protein stability, and nucleic acid integrity over extended storage periods. With dimensions of 82.0 × 46.5 × 45.5 cm, the unit provides compact storage capacity while delivering the temperature stability required for critical sample preservation in research environments.
How It Works
Ultra-low temperature freezers achieve -86°C operation through cascaded refrigeration systems utilizing multiple compressors and refrigerant circuits. The primary refrigeration circuit pre-cools the chamber, while a secondary ultra-low temperature circuit achieves the final target temperature through staged cooling processes.
Temperature stability is maintained through advanced insulation materials, typically polyurethane foam with vacuum panels, which minimize heat transfer and temperature fluctuations. Microprocessor-based control systems monitor internal temperatures through multiple sensors and adjust compressor operation to maintain setpoint temperatures within specified tolerances.
The freezer incorporates safety features including temperature alarms, backup systems, and insulated construction designed to maintain sample integrity during power interruptions or equipment maintenance procedures.

Practical Tips
Verify temperature accuracy using calibrated reference thermometer placed in chamber geometric center during monthly calibration checks.
Why: Center placement provides most representative temperature reading for overall chamber performance assessment.
Clean condenser coils quarterly and replace air filters according to manufacturer schedule to maintain cooling efficiency.
Why: Dirty coils and filters reduce cooling capacity and increase energy consumption while stressing refrigeration components.
Pre-cool samples to -20°C before transferring to ultra-low freezer to minimize temperature recovery time.
Why: Gradual temperature reduction reduces thermal shock to both samples and freezer refrigeration system.
If temperature alarms activate, check door seals and minimize door openings while monitoring temperature recovery.
Why: Door seal integrity is critical for maintaining ultra-low temperatures and preventing excessive compressor cycling.
Document door opening events and duration in temperature logs to correlate with any temperature fluctuations.
Why: Temperature excursions from door openings can affect sample integrity and should be tracked for quality control.
Ensure adequate ventilation around the unit and check that emergency alarm systems are connected to laboratory monitoring.
Why: Proper ventilation prevents overheating while alarm connectivity ensures immediate response to temperature failures.
