Product Overview
Labotemp Laboratory Freezer LDF-13 is a 485-litre chest freezer designed for reliable long-term storage of vaccines, blood plasma, reagents and biological samples in laboratories, blood banks and clinical facilities. Operating between -20°C and -40°C, the LDF-13 uses a CUBIGEL compressor with eco-friendly R290 refrigerant and high-efficiency direct cooling to provide stable temperature control. Temperature is monitored by an NTC sensor and a microprocessor controller with digital display (0.1°C resolution). Construction includes a stainless steel interior, ≥100 mm PURF insulation and a foamed solid door to ensure thermal integrity.
