LF25-280W -25°C Upright Biomedical Freezer

The LF25-280W is a vertical biomedical freezer with a 278 L capacity and a microprocessor-controlled temperature range of -10°C to -25°C at ambient temperatures from 10 to 32°C. An NTC sensor and LED digital display provide clear, stable control, and the unit can run at its lowest temperature for long periods.

An independent inner door reduces cold air loss when the outer door is opened, and seven drawers organise samples. Insulation is high-density CFC-free urethane foam, and the cooling system uses environmentally safe R290 refrigerant with manual defrost. The upright side door has a built-in handle and a hinge limit to prevent collisions, and lockable casters allow the freezer to be moved.

Alarms cover high and low temperature, sensor error, power off, controller malfunction and door ajar, with both audible and flashing light indication. A start-delay protects the compressor after power failure, a password protects the settings, and the unit tolerates supply voltages from 187 to 242 V. A test hole of 25 mm and an optional temperature data logger are provided.
