National Lab laboratory freezer Thorbi Genius TGF265G
The National Lab laboratory freezer Thorbi Genius TGF265G with glass door and high-quality LED interior lighting is a powerful and energy-efficient solution for demanding laboratories. Even in temperature-critical environments, it ensures consistently low temperatures of -10 °C to -30 °C. It therefore stands out from many conventional laboratory freezers, which often lack precise temperature control, durable construction and user-friendliness. Similarly equipped appliances such as the [National Lab Laboratory Freezer Revo 100] are used in comparable application scenarios, but do not always achieve the same combination of space and ease of use.
Performance features and design details
The laboratory freezer was developed with precise temperature control, ease of maintenance and user convenience in mind. The result is a technically sophisticated, robust and user-friendly freezer solution that hardly causes any space problems, even in densely populated laboratory environments. Its climate class 4 rating makes it ideal for a room temperature of up to 30 °C at 55 % relative humidity.
Thanks to the rounded interior corners, the appliance is particularly easy to clean; the reduced risk of contamination makes it the ideal choice for laboratory locations with high hygiene requirements. The heated door frame also prevents ice from forming on the door, which in turn promotes a constant cold environment inside the chamber. The generous capacity of 521 liters offers plenty of scope for anyone who needs to cool large quantities of samples and materials. The freezer also scores highly with its three-chamber seal, which can be replaced quickly if necessary.
Important key technical data:
- Temperature range: -10 °C to -30 °C
- Internal volume: 521 liters
- External dimensions (WxDxH): 687 × 853 × 1955 mm
- Climate class: 4 (optimized for up to 30 °C room temperature and 55 % r. h.)
- Compartments/shelves: 7 shelves, 25 kg load each
- Automatic defrosting (hot gas defrosting)
- Natural refrigerant (R290)
In addition, the equipment includes an easy-to-understand digital controller with touchscreen, which enables quick setpoint input and precisely compensates for even the smallest temperature fluctuations. Alarms, for example in the event of temperature deviations or an open door, are both visual and audible and significantly increase operational safety.
Similar appliances such as the [National Lab Laboratory Freezer Premium TGF380] also rely on an ergonomic door opening with stay-open function and benefit from corrosion-resistant epoxy coatings in the evaporation system, but differ to some extent in terms of volume and footprint.
Certifications and standards
As with all professional laboratory refrigerators and freezers from standard manufacturers, this model is also CE-certified. In addition, each condenser unit is tested in helium chambers for any leaks, which underlines the high safety standard and quality of workmanship.
Application examples
- Long-term storage of biochemical reagents and enzymes in the temperature range from -10 °C to -30 °C.
- Storage of biological samples such as cell cultures, bacterial strains or viral particles.
- Storage of temperature-sensitive chemicals, e.g. diethyl ether, acetonitrile or methanol samples.
- Used in the pharmaceutical and food industries for the temporary storage of product-specific substances that need to be kept deep-frozen.
FAQs
How easy is the temperature control
?
The integrated touchscreen control allows for quick adjustment, while the NTC temperature sensor system ensures precise control. Deviations are detected immediately and compensated for accordingly.
What maintenance measures are required
Regular visual inspections of the door frame, seals and interior are sufficient. If necessary, the easily accessible design supports maintenance. Automatic hot gas defrosting significantly reduces manual defrosting intervals.
Is the appliance mobile?
Thanks to four built-in castors - two of which are lockable - the appliance can be moved or repositioned as required. However, with a depth of 853 mm and a height of 1955 mm, it is advisable to plan the intended installation location precisely in advance.
How are sensitive samples protected from excessive temperatures?
The air circulation system stops when the door is opened to prevent loss of cold. The appliance also sends audible and visual alarms as soon as preset limit values are exceeded. A lock on the door additionally secures samples against unauthorized access.
What materials are used in the interior?
The interior is made of AISI 304 stainless steel, which promotes durability and reduces the need for cleaning. The shelves are also made of high-quality stainless steel and can support up to 25 kg per level.
Conclusion
Thanks to its robust design, precise temperature control and user-friendly design details, this model is recommended for laboratories that place high demands on a constant deep-freeze environment. The sturdy stainless steel interior, heated door frame and simple touchscreen operation make it a reliable, durable and ergonomic choice for a wide range of applications in research, industry and science.
