-40⁰C Upright Freezer LUF-B60

Engineered -40?C Upright Freezer LUF-B60 offers highly accurate temperature control (±1?°C) through a precision microprocessor and LCD display, ensuring consistent conditions for sensitive materials like enzymes, vaccines, reagents, and DNA/RNA. Its manual defrost mechanism eliminates temperature fluctuations caused by automatic defrosting, preserving sample integrity. Integrated alarms alert users to any temperature drift or door left open, while the PCM-coated interior ensures easy cleaning and sample safety in sterile environments.

Designed -40?C Upright Freezer LUF-B60 runs quietly at just 52?dB and avoids high energy surges thanks to its manual defrost system. The PCM-insulated cabinet helps retain cold air, reducing overall power consumption. With a power rating between 210–350?W (depending on input voltage), it offers economical long-term use. Battery-supported alarms provide continuous monitoring with minimal energy usage, while quiet operation makes it suitable for use in shared or bench-side lab spaces.

The -40?C Upright Freezer LUF-B60 is equipped with a complete alarm system for high/low temperature, door ajar, power failure, high ambient temperature, and high condenser temperature. A dependable battery backup ensures up to 20 hours of alarm and display functionality during power outages. The freezer provides both visual and audio alerts for rapid response. USB interfaces allow users to track, record, and review alarm events, and the manual defrost system further supports stable operation without unexpected temperature spikes.

Yes, the -40?C Upright Freezer LUF-B60 supports data logging and remote access via USB connectivity, allowing automatic temperature log exports for compliance and documentation. It is compatible with BMS and LIMS platforms, enabling integration into broader monitoring networks. Real-time alerts through connected systems allow lab personnel to react quickly to any abnormalities. The microprocessor controller also stores historical data internally, enhancing traceability in regulated environments

Our -40?C Upright Freezer LUF-B60 features regular manual defrosting is essential to prevent ice build-up. Cleaning and inspecting condenser coils, fans, and door gaskets annually helps sustain cooling efficiency. Gaskets should be replaced as needed to maintain a proper seal. Battery-powered alarm systems should be tested biannually to ensure functionality. Routine calibration is advised to confirm that the unit maintains its ±1?°C accuracy. For best results, position the freezer away from direct heat sources or air vents to reduce frost accumulation and compressor strain.

Labtron’s -40?C Upright Freezer LUF-B60 model uses R290 refrigerant, a hydrocarbon gas that is both energy-efficient and environmentally friendly. R290 has a low Global Warming Potential (GWP) and offers excellent thermodynamic performance, resulting in faster cooling with lower power consumption. The PCM-coated body (Pre-Coated Metal) enhances insulation and reduces heat loss. The manual defrost system eliminates power-intensive auto-defrost cycles, helping save energy while maintaining temperature stability. Operating at just 260 W, the freezer delivers efficient performance without sacrificing cooling power. It supports labs in reducing their carbon footprint and electricity costs.
