OverviewThe Labotemp LDF-12 is an ultra-low temperature chest freezer designed for secure storage of temperature-sensitive laboratory and medical materials. With a 770 L capacity and an adjustable range from -25°C to -60°C, the unit combines a high-efficiency Secop compressor and direct cooling to deliver uniform low temperatures and rapid recovery after lid opening. Digital tube display with PT1000 probe and audible/visual alarms provide precise monitoring and alerting to protect stored samples.
Construction & PerformanceConstructed for laboratory use, the LDF-12 features 100 mm insulation to minimise thermal loss. The interior is 304 stainless steel for hygiene and easy cleaning; the exterior uses epoxy-polyester powder-coated steel for corrosion resistance. Temperature is managed by a KELD controller. Rated for 220V/50Hz operation, nominal power 550 W and 10 kW/24h consumption, the unit suits research, clinical and biobank environments.
