National Lab laboratory freezer Thorbi Genius TGF240S
The National Lab Laboratory Freezer Thorbi Genius TGF240S is a precise and reliable solution for laboratories where an accurate and constant low temperature is required for samples, reagents or other temperature-sensitive materials. With its advanced temperature control and robust construction, this model combines high efficiency, ease of use and durability. Comparisons with the National Lab laboratory freezer Thorbi Ultimate TGU200 show that even with different sizes and performance specifications, the sophisticated refrigeration systems from National Lab remain constant, ensuring reliable use in everyday laboratory work in every case.
Thanks to the high-quality insulation and optimized door seal, professional users do not have to compromise on safety or reliability. A self-closing function and the heated door frame help to reduce the risk of ice formation and preserve valuable samples in the best possible way. An additional comparison with the National Lab laboratory freezer Thorbi Master TGF300 illustrates how flexibly the Thorbi series can be adapted to a wide range of laboratory requirements.
Performance features and special features
Laboratories generally require a cooling appliance that is neither too loud nor consumes too much energy at optimum performance. This freezer meets precisely these requirements and also offers special features:
- Temperature range from -10 °C to -30 °C, ideal for demanding applications.
- Maximum precision thanks to digital controller with touchscreen and a control accuracy of 0.1 °C.
- Energy-efficient LED lighting in the interior makes it easier to find and assign samples.
- Automatic hot gas defrost to reduce maintenance and ensure consistent performance.
- High-pressure polyurethane insulation (CFC-free) to protect the refrigerated goods from - sometimes considerable - temperature fluctuations outside the appliance.
- Robust door sensor that automatically stops the recirculating air evaporator when opened.
- Heatable door frame for ice-free closing even with frequent door use.
With an internal volume of 366 liters, the freezer is generously dimensioned and offers enough space on seven height-adjustable shelves for different types of laboratory utensils - from sample tubes and reagents to larger sample containers. Each segment level can hold up to 25 kg, which is both flexible and safe. In addition, the door hinge (on the right as standard, but can be changed at the factory) enables optimum adaptation to the available space.
The high-quality white sheet steel, plastic-coated on both the outside and inside, ensures a corrosion-resistant and easy-to-clean surface. Rounded interior corners and the clear design of the interior allow regular, quick and intensive cleaning processes when required in everyday laboratory work.
The freezer is also impressive when it comes to alarm management. Visual and acoustic signals provide information in the event of incorrect temperatures or if the door is left open for too long. The integrated lock option provides additional protection for valuable contents - this is particularly important in laboratory environments with high standards of hygiene and storage.
Certifications and standards
As a professional laboratory freezer, this appliance complies with a wide range of directives and standards, such as CE conformity. Climate class 4 (30 °C, 55 % relative humidity) confirms its suitability even under demanding environmental conditions. The environmentally friendly, "green" refrigerant R290 is used here, which has a significantly lower impact on the environment thanks to ODP=0 and GWP<1.
Concrete application examples
- Storage of temperature-sensitive enzymes: The constant temperature range guarantees long-term stability, especially for enzymes that decompose quickly.
- Storage of biological samples: For human and animal studies, temperatures around -20 °C are often required to slow down decomposition processes.
- Storage of cell cultures: Cell cultures are often stored at low temperatures for research purposes in order to preserve their structure.
- Storage of sensitive solutions and reagents: Particularly in areas such as molecular biology or biotechnology, a reliable deep-freeze system is essential to maintain consistent quality standards.
FAQs
How easy is it to set the temperature
?
The desired temperature can be set precisely in 0.1 °C increments using the user-friendly digital controller with touchscreen. The menu navigation is straightforward and intuitive to understand.
What happens if the door is accidentally left open
The appliance has acoustic and visual alarm functions that are triggered if the temperature rises and the door is left open for a longer period of time. In addition, the stay-open function prevents the door from closing unnoticed during loading or unloading when the door is open more than 95 degrees.
Is regular maintenance necessary?
In addition to automatic defrosting and the high-quality refrigerant R290, only minimal maintenance is required. However, manufacturers and experts recommend that cooling units are checked regularly to ensure that the condenser and interior are clean.
Is the freezer suitable for flammable substances?
As this is an appliance with a convection-cooled system and epoxy-coated evaporator, the focus is on the safe storage of sensitive but largely standardized laboratory samples. For highly flammable substances, the safety regulations should always be checked by a specialist.
Conclusion
The Thorbi Genius TGF240S offers an optimal solution for laboratories from a wide range of specialist areas thanks to its robust design, precise cooling system and diverse safety functions. At the same time, the appliance impresses with its intuitive use, sample-oriented storage structure and comparatively low maintenance requirements. This makes the National Lab laboratory freezer Thorbi Genius TGF240S the preferred choice in many areas of application where an extremely reliable cooling solution for temperature-sensitive samples is required.
