Labotemp Laboratory Freezer LDF-13 is a high-capacity chest freezer engineered for reliable long-term storage of vaccines, blood plasma, reagents, and biological materials in research institutions, clinics, and medical facilities. With a 485-litre chest design and temperature range of -20°C to -40°C, this Laboratory freezer delivers stable, consistent cooling for temperature-sensitive samples requiring dependable preservation.
Powered by a CUBIGEL compressor with eco-friendly R290 refrigerant and high-efficiency direct cooling, the LDF-13 ensures excellent thermal stability and energy-efficient operation at just 300W. The microprocessor controller with digital display and NTC sensor provides accurate temperature monitoring with 0.1°C precision. A stainless steel interior, 100mm PURF insulation, and foamed solid door maintain reliable thermal integrity, while comprehensive audible and visual alarms covering temperature deviation, sensor failure, controller error, and 12-hour power failure protection ensure continuous sample security. Controller error memory protection maintains normal cooling cycles even after sensor or controller faults. Caster wheels with stoppers and a service-free drainage system support convenient daily operation.
