National Lab laboratory freezer Thorbi Genius TGF225S
The National Lab Laboratory Freezer Thorbi Genius TGF225S is ideal for demanding applications in laboratory environments where precise and reliable storage of temperature-sensitive samples and materials is required. Thanks to its sophisticated design features and high-quality components, this model offers a high level of safety and consistency that sets it apart from many other freezers on the market. Similar features can be found, for example, in the FRYKA UC-200 laboratory freezer, which covers similar temperature spectrums.
Powerful and reliable refrigeration technology
Thanks to the integrated air circulation system and automatic hot gas defrosting, the appliance ensures a constantly low temperature in the range from -10 °C to -30 °C. At the same time, the corrosion-resistant epoxy coating of the evaporator provides long-term protection against wear and contributes to a long service life. The high-density polyurethane insulation prevents thermal bridges and thus increases energy efficiency. In addition, the R290 refrigerant used is particularly environmentally friendly as it is free from ozone-depleting substances (ODP=0).
A digitally controlled temperature regulator with touchscreen also enables precise adjustment of the desired cooling value - with an accuracy of up to 0.1 °C. This ensures that sensitive substances can be stored optimally even in slightly fluctuating ambient conditions. Should a malfunction nevertheless occur or if the door is accidentally left open, the appliance immediately gives an acoustic and visual warning of a possible temperature rise.
Developed for demanding laboratory practice
Easy cleaning and robust handling are essential in many laboratory areas. That's why the interior and exterior surfaces are made of white plastic-coated, galvanized sheet steel with rounded edges. The door features a reliable lock so that important samples are always kept safe. As a special detail, the door has a sensor to automatically stop the air circulation system when it is opened, ensuring efficient and resource-saving cooling.
The self-closing door mechanism with stay-open function is also designed for everyday laboratory use: If the door remains open through an angle of 95 degrees, users can put samples in and take them out at their leisure without it slamming shut again. It then closes automatically and prevents accidental opening. The heated door frame construction also guarantees an ice-free door and contributes to consistently low energy consumption.
Important key technical data at a glance
- Temperature range: -10 °C to -30 °C
- Volume: 242 liters
- External dimensions (W × D × H): 670 × 706 × 1538 mm

Frequently asked questions (FAQ)
How often should the door be opened?
As rarely as possible to avoid temperature fluctuations. Although the appliance has a robust temperature control, frequent opening increases the energy requirement and briefly affects the internal temperature.
Are there any special requirements for the ambient temperature?
Yes, the appliance is designed for climate class 4 (30 °C, 55 % relative humidity). In environments with higher temperatures, you should ensure sufficient ventilation so that the cooling unit can work effectively.
What happens in the event of a power failure
The robust refrigeration circuit and strong insulation ensure that the internal temperature remains stable for a certain period of time. Nevertheless, it is advisable to check the samples regularly and use backup systems if necessary.
Is the device easy to clean?
Yes, thanks to its plastic-coated surfaces and rounded interior corners, the interior can be cleaned quickly and thoroughly. Contamination or leaking substances can be easily removed without leaving gaps or small corners inaccessible.
Conclusion
This freezer from National Lab combines high-precision temperature control with a robust construction that is specially designed for everyday laboratory use. From the powerful convection cooling to the user-friendly door mechanism and effective alarm function, the appliance is designed to keep valuable samples and materials safe at consistently low temperatures. If you are looking for reliability, energy efficiency and intuitive operation, this model is a sustainable and well thought-out solution for a wide range of laboratory applications.
