Sample storage freezer LDF-19

for clinical laboratoriesfor biobanksfor vaccines

Overview
Labotemp LDF-19 is a compact laboratory freezer providing reliable ultra-low storage from -25°C to -60°C with 0.1°C control accuracy. Its direct-cooling refrigeration, 100 mm PURF insulation and stainless-steel interior deliver stable conditions for vaccines, biological samples, reagents, enzymes and other temperature-sensitive materials used in research, clinical and pharmaceutical environments.

Cooling, Safety & Operation
The unit features a direct-cooling system driven by a single CUBIGEL compressor and uses refrigerant R4001 (170 g). Safety and monitoring include lockable door, visual and audible high/low temperature alarms, sensor and controller error alarms, and power-interruption protection. Operational functions include manual defrost, service-free drainage, integrated test port for validation/monitoring and lockable castors for mobility.
