PHCBi TwinGuard DU702/DU302 -86°C Ultra Low Temperature Freezer
Product Description
The PHCBi TwinGuard Ultra Low Temperature Freezer, models DU702 (25.7 cu.ft./729 L) and DU302 (12.7 cu.ft./360 L), delivers reliable freezing down to -86°C with advanced twin compressor technology for redundancy and rapid temperature recovery. Designed for critical long-term storage in biotechnology, molecular diagnostics, and biopharmaceutical production, this upright ULT freezer features:
- Twin compressors working independently and in tandem, ensuring continuous cooling and backup
- Temperature control range from -50°C to -86°C with 1°C increments, ideal for sensitive biomaterial preservation
- Unique vacuum insulation panels combined with foamed-in insulation to enhance thermal stability while maximizing storage capacity
- Solid external door plus two insulated sub-doors for minimized temperature fluctuations during sample access
- High-contrast LCD touchscreen with graphic interface, comprehensive alarms (high/low temp, power failure, door ajar, fan issues), diagnostics, data logging, and USB connectivity for remote monitoring and data export
- Three access ports for additional monitoring systems, backup connections, or instrumentation integration
- Stainless steel shelves with 110 lbs (50 kg) load capacity per shelf, supporting diverse storage needs
- Refrigerant with mixed Hc/Hfc blend for efficient cooling aligned with safety and environmental standards
- ECO mode operation available to optimize energy consumption and cost-effectiveness
This ULT freezer is widely used across cell imaging, synthetic biology research, and bioprocessing workflows, making it an essential asset in environments requiring stable cryogenic temperature conditions for live-cell preservation, enzyme storage, and high-value biological sample management. Its ergonomic handle and quiet operation (52 dB(A)) increase usability in demanding laboratory settings.
With comprehensive alarm systems and optional password protection, the PHCBi TwinGuard freezer supports secure, uninterrupted storage critical in clinical diagnostics, biomanufacturing, and gene editing facilities, ensuring sample integrity through consistent ultra-low temperature control.
