Description
Labotemp -86°C Ultra Low Freezer ULF-28 is a high-capacity laboratory ULT freezer for secure long-term preservation of biological materials at ultra-low temperatures from -40°C to -86°C. Designed for clinical, biobanking and research environments, it provides stable and uniform cooling via a dual cascade refrigeration system with automatic backup to maintain critical samples in case of primary system failure.

Design and control
The ULF-28 features a microprocessor control with a 7-inch touchscreen for precise monitoring (±0.1°C). The cabinet combines VIP insulation and PURF to optimize thermal stability and energy use. Stainless steel interior and a double-insulated door improve hygiene and reduce temperature fluctuation. Safety systems include multi-alarms, door lock, 72-hour controller battery backup and power-failure protection.
