Product overview
The Labotemp Ultra‑Low Temperature Freezer ULF‑27 is an upright ULT solution engineered for pharmaceutical, clinical and research laboratories. With a 408 L capacity it provides rapid pull‑down performance and stable temperature control from −40°C to −86°C with 0.1°C regulation accuracy, suitable for vaccines, viral samples, tissues, reagents and biobank storage.

Key features

• Dual SECOP compressors with automatic failover — capable of maintaining −70°C on a single compressor.
• Optional LN₂ / CO₂ emergency backup for critical alarm scenarios.
• Cascade refrigeration using eco‑friendly R290 / R170 refrigerants for energy‑efficient operation (~13.8 kWh/24h).
• Advanced insulation: 100 mm PURF combined with Vacuum Insulation Panels (VIP) for improved thermal stability.
• 7" microprocessor touch controller with PTC sensors for accurate monitoring and control.
• Data connectivity: USB data download port, RS485 interface and remote alarm port.
• Comprehensive alarm suite including high/low temperature, power‑failure (72 h battery backup), sensor and controller error, door ajar and condenser/filter alerts.
• Certified to ISO 13485 and CE standards.

Applications

• Pharmaceutical, clinical, biotechnology and research laboratories requiring secure ultra‑low temperature storage.
• Long‑term preservation of vaccines, viral samples, biological specimens, reagents, tissues and biobank materials at stable −86°C conditions.
