Product overview
Labotemp Upright laboratory freezer LDF-20 is a laboratory deep freezer for secure storage of biological materials, vaccines, blood plasma, reagents, enzymes and other temperature-sensitive samples. Temperature range: -20°C to -40°C. Net capacity: 278 L. Seven removable drawers provide organised storage and easy access to samples.

Design & Operation
Designed for continuous laboratory use: coated-steel cabinet, 85.5 mm high-density PURF insulation and direct-cooling system driven by a CUBIGEL compressor using R290 refrigerant. A microprocessor controller with NTC sensor and digital display maintains temperature with ±0.1°C precision. Audible and visual alarms cover high/low temperature, door ajar, sensor failure and controller fault. Door lock and controller password restrict access. Power-failure recovery restores previous settings automatically after power returns. Four lockable castors enable relocation and stable placement.
