-40⁰C Upright Freezer LUF-B70

Labtron’s -40?C Upright Freezer LUF-B70 ensures rapid temperature recovery after frequent door access, maintaining sample integrity. Its high-efficiency cooling system and PCM insulation reduce thermal fluctuation, ideal for high-traffic research or clinical labs. Powered by eco-friendly R290 refrigerant, it cools faster while minimizing environmental impact. The internal door seals minimize cold air loss, helping restore target temperatures quickly. An intuitive LED temperature display provides real-time monitoring, while door ajar alarms enhance sample protection.

The -40?C Upright Freezer LUF-B70 features a multi-point alarm and safety system for secure cold storage. It provides real-time alerts for high/low temperatures, door ajar, sensor errors, and power failure. Audible and visual alarms ensure immediate notifications in case of deviations. The integrated battery backup supports alarm functions during outages, maintaining compliance with GMP/GLP standards. Ambient and condenser temperature alerts help protect components and prevent overheating.

To ensure optimal performance, the -40?C Upright Freezer LUF-B70 scheduled manual defrosting to prevent ice build-up. Users should routinely clean gaskets, inner compartments, and condenser coils to maintain hygienic and efficient operation. Battery health checks are recommended to ensure uninterrupted alarm activity during power loss. The built-in USB data logger allows long-term monitoring and compliance tracking. Following the maintenance guide extends the lifespan and enhances the performance of this laboratory-grade freezer.

Yes, the -40?C Upright Freezer LUF-B70 operates reliably in ambient temperatures up to 32°C, making it suitable for warm lab environments. With an N climate class rating and PCM insulation, it maintains stable internal cooling even under thermal stress. The rear-ventilation design ensures consistent airflow, reducing overheating risks. Condenser alarms provide early warnings if ambient conditions affect cooling performance. Proper placement away from heat sources enhances energy efficiency and system reliability.

Our -40?C Upright Freezer LUF-B70 is ideal for biomedical storage, vaccine preservation, clinical research, and pharmaceutical cold storage. It safely stores sensitive materials including enzymes, reagents, DNA/RNA samples, and drugs. Suitable for hospitals, diagnostic labs, universities, forensic labs, and veterinary facilities. Its dual-chamber design allows efficient sample separation and inventory management. Its compliance with cold chain and quality protocols makes it ideal for regulated environments. All features are designed to meet the needs of labs requiring secure, uninterrupted cold storage.

Designed -40°C Upright Freezer LUF-B90 delivers precise cooling performance with a temperature accuracy of ±0.1°C, essential for sensitive sample preservation. Its dual-temperature, dual-control microprocessor system allows stable and independent management of both compartments. Users can monitor and adjust the temperature via the intuitive LED display panel. This ensures real-time visibility and helps maintain exact storage conditions at all times. The manual defrost design also prevents sudden temperature fluctuations common in auto-defrost models.
