Reliable -86°C Sample Preservation with the Ultra Low Temperature Freezer DDF-8628
Protect your most valuable biological assets with the Ultra Low Temperature Freezer DDF-8628—a high-performance, energy-efficient ULT freezer engineered for long-term storage of vaccines, cell lines, DNA/RNA, enzymes, and clinical specimens at –86°C. Designed to meet CLSI C27-A, FDA, GxP, and WHO standards, the DDF-8628 delivers exceptional temperature stability, rapid recovery, and robust security for biobanks, pharmaceutical labs, and research institutions.
Engineered for Stability, Efficiency, and Sample Integrity
The DDF-8628 Ultra Low Temperature Freezer features a 280-liter capacity with horizontal or vertical configuration options and high-density insulation for minimal heat transfer. Its advanced cascade refrigeration system maintains a uniform temperature of –86°C ±3°C, even during frequent door openings, while the rapid pull-down and recovery ensures sample safety during power fluctuations or restocking. The unit includes audible/visual alarms, remote monitoring capability, and a backup battery for continuous temperature logging.
- Precise Temperature: –86°C (Range: –50°C to –86°C) – Ideal for sensitive biologics and long-term archival storage.
- 280-Liter Capacity with Adjustable Shelves & Inner Door Compartments – Stores up to 20,000 x 2 mL cryovials or standard freezer boxes.
- Energy-Saving Technology – Eco-friendly refrigerants (e.g., R290/R170 blend) and VIP insulation reduce power consumption by up to 30% vs. conventional ULT freezers.
- Comprehensive Alarm System – High/low temperature, power failure, door ajar, and sensor fault alerts with optional Wi-Fi/email notifications.
- Lockable, Sealed Door with Triple Gasket – Minimizes cold loss and prevents contamination.
- Data Logging & Compliance Ready – Optional 21 CFR Part 11-compliant recorder for audit trails and validation support.
Trusted in Biobanking, Pharma, and Advanced Research
From storing CAR-T cells and mRNA vaccines to preserving genomic libraries and tissue samples, the DDF-8628 ensures sample viability over years or decades. Its reliability, low maintenance, and compliance-ready design make it ideal for ISO 20387, GMP, and clinical trial environments where temperature excursions can compromise irreplaceable materials.
Whether you’re managing a core facility or scaling vaccine R&D, the Ultra Low Temperature Freezer DDF-8628 delivers the performance, security, and peace of mind your science demands.
Preserve the future. One degree at a time.
