-86 °C Ultra Low Temperature Upright Freezer LUF-C31

The Labtron -86 °C Ultra Low-Temperature Upright Freezer is specifically designed for storing highly sensitive materials that need extremely low temperatures for long-term preservation. It is commonly used in industries such as life sciences, pharmaceutical research, bio-banking, blood banks, clinical laboratories, and vaccine production facilities. These fields require safe storage of biological samples, vaccines, enzymes, and other materials that are temperature-sensitive. With its stable temperature range from -40°C to -86°C and reliable insulation, this Labtron freezer ensures that valuable samples remain uncompromised over time.

The freezer uses a single, efficient compressor and a direct cooling system to rapidly achieve and consistently maintain ultra-low temperatures down to -86°C. The temperature is managed by a microprocessor-based controller, which allows for precise adjustments and stable operation. It also includes a digital display that shows current temperature, alarms, and system status clearly, making it easy for users to monitor and control the freezer's performance. The use of PURF insulation ensures minimal temperature loss and energy efficiency.

Labtron has equipped this freezer with multiple audible and visual alarm systems to protect stored contents. These alarms notify users in case of issues like high or low temperatures, power failures, abnormal voltage, sensor errors, door left open, low battery, and even when the condenser or filter needs cleaning. There's also a 72-hour power failure alarm, which alerts users if a power outage lasts too long. These safety features are essential for laboratories or facilities where the loss of sensitive samples could have major consequences.

The freezer is built with high-quality materials to ensure long-term durability. Its interior is made of stainless steel, which is corrosion-resistant and easy to clean. The exterior is made of color-sprayed steel, offering a clean, professional look and resistance to external wear. It has a single stainless steel shelf inside, making it simple to organize stored items. Despite its powerful performance, the unit maintains a relatively low noise level of 50 dB, making it suitable for labs and clinical settings. The manual defrost function gives users control over maintenance.

This upright model has a storage capacity of 58 liters and operates within an ambient temperature range of 10°C to 32°C. It uses R4001 mixed gas as a refrigerant and is powered by a 3.18A compressor with a power consumption of 6.09 kWh per day. The freezer runs on a 220V/50Hz power supply and has a total power rating of 442 W. In terms of size, its internal dimensions are 330 × 453 × 410 mm, and the external dimensions are 635 × 757 × 1212 mm. With a net weight of 112 kg, it is compact yet sturdy, making it easy to integrate into most laboratory spaces.
