Overview
Labotemp Ultra Low Temperature Freezer ULF-29 is designed for long-term preservation of temperature-sensitive biological materials in laboratories, hospitals, biobanks and research facilities. The 305 L chest layout and operating range of -60 °C to -86 °C provide stable ultra-low storage for viruses, vaccines, plasma, tissues, reagents and other critical samples. A microprocessor controller with digital display and PTC sensor enables temperature monitoring with 0.1 °C precision. The 304 stainless steel interior and ≥100 mm PURF insulation maintain thermal integrity during continuous operation.

Security & Operation
Multi-level audible and visual alarm systems cover high/low temperature deviation, sensor failure and controller faults to protect stored samples. Power-failure memory protection preserves cooling cycles after system faults. A safety door lock prevents unauthorized access. Sturdy castors with stoppers and a service-free drainage arrangement support safe movement and practical daily laboratory handling.
