Laboratory refrigerator or freezer TEFCOLD SE10-45

A laboratory freezer maintains temperatures below the freezing point of water to preserve samples, reagents and biological materials without ice crystal damage. It removes heat from the interior through a refrigeration cycle: a compressor circulates refrigerant, which absorbs heat as it evaporates inside the cabinet and releases it outside through a condenser coil. The process is continuous, keeping the air inside uniformly cold and dry. An electronic thermostat monitors the temperature and adjusts the compressor to hold the set point, while an alarm alerts the operator if the temperature drifts beyond safe limits. The SE152 L freezer is loaded by opening the door and placing items on the basket or directly on the shelves. The electronic thermostat is set to the required temperature between -45 °C and -5 °C. Once the door is closed, the refrigeration cycle starts automatically. The operator checks the digital display for the current temperature and alarm status. When items are removed, the door is closed promptly to prevent warm air from entering and raising the internal temperature. The cabinet is constructed from white-coated steel, chosen for durability and ease of cleaning in laboratory environments. The interior includes a removable basket for organised storage. Four castors, two of which have brakes, allow the freezer to be moved across the floor and then secured in place without rolling. The electronic thermostat controls the temperature setting, while the alarm monitors deviations from the set point. The display shows the current temperature and alarm status, allowing the operator to respond quickly to any fault. A 152 L volume provides space for multiple sample boxes or reagents, while the -45 °C to -5 °C range covers ultra-low storage for biological materials and standard freezing for general laboratory use. The 0.25 kW power rating indicates the load on the electrical circuit, which must support 220-240 V at 50 Hz. The 49 kg weight allows the unit to be moved by one person, and the 734 mm width, 705 mm depth and 945 mm height determine the floor space and clearance required in the laboratory. After each sample batch, the smooth inner walls and rounded corners let you swab down the chamber without leaving residue in crevices that could cross-contaminate future experiments. The basket is removed and washed separately. The castors are checked periodically to ensure they roll freely and the brakes hold securely. The SE152 L is a single model with no variants. The product is listed in the laboratory refrigeration section of the catalogue.
