National Lab Thorbi Primus TPU5086DCC ultra-low temperature freezer
The National Lab ultra-low temperature freezer from the Thorbi Primus series is a powerful solution for highly sensitive samples that need to be stored in the pharmaceutical, biotechnology and chemical industries as well as in research laboratories. With its Double Cooling Circuit Technology, extensive safety features and robust refrigeration system, it clearly stands out from other freezers on the market. Although similarly flexible applications such as the [Pol-Eko SUF85] also offer effective cooling performance, the model presented here also focuses on maximum reliability and state-of-the-art control elements.
Powerful deep-freeze technology
In order to ensure a constant storage temperature of -40 °C to -86 °C, the manufacturer has integrated two independently operating cooling circuits. This double cooling circuit technology ensures the necessary temperature stability on the one hand and reliable protection in the event of a system failure on the other, as the remaining compressor is able to maintain the internal temperature at -70 °C. In addition, the manufacturer relies exclusively on natural and biodegradable refrigerants - in accordance with the European F-Gas Regulation - to ensure both efficiency and environmental friendliness.
The high-quality vacuum insulation panel (VIP) technology in combination with high-pressure polyurethane (CFC-free) also noticeably reduces unwanted thermal bridges, which ensures low operating costs, high storage reliability and outstanding energy efficiency. An integrated data logger and USB interface also simplify the traceability of temperature data.
The sophisticated alarm concept is particularly noteworthy. In addition to visual and acoustic signals in the event of increased internal temperatures or doors accidentally left open, the system also monitors the function of central sensors. This not only provides comprehensive protection for the contents, but also ensures smooth operation.- Temperature range: -40 °C to -86 °C
- Usable capacity: 522 liters
- External dimensions (WxDxH): 996×975×1997 mm
- Interior: AISI 304 stainless steel with rounded corners
- Refrigerant: R600a / R1150 (HC)
- Alarm management: Visual & acoustic warning signals, backup battery
- Door system: 1 full door with lock and 4 inner doors
The door seal is designed to be easily replaceable and is equipped with a door frame heater to prevent freezing. For flexible use in the laboratory, four lockable castors with integrated adjustable feet are included as standard. Thanks to the robust design and the temperature-stable inner housing, even temperature-sensitive substances such as cell cultures, vaccines or sensitive reagents can be stored long-term without any concerns.
Last but not least, the intuitive 5-inch touchscreen control simplifies operation and monitoring. The high measuring accuracy (0.1 °C) of the integrated PT1000 sensor provides stable values so that quality-relevant processes run reliably. Some competitor models, such as the [Labcold LR-80], also have modern control technology, but the device presented here scores points with its particularly user-friendly interface and continuous data evaluation.
Application examples
- Long-term storage of particularly cold-sensitive vaccines and experimental substances
- Safe storage of cell and tissue samples in basic research
- Deep-freezing of rare chemicals that require a constant low temperature
- Sample storage for microbiological tests in diagnostic laboratories and university institutes
In many laboratory applications where reliable, consistent cooling is essential, this ultra-low temperature freezer turns out to be an essential component to ensure quality and reproducibility

FAQs
How often does the freezer need to be defrosted
?
The appliance has a manual defrosting system. In practice, it has been shown that regular defrosting is rarely necessary in everyday laboratory use. If ice does form, it is sufficient to carry out a scheduled defrost at set intervals to maintain optimum performance.
What happens in the event of a compressor failure
Thanks to the Double Cooling Circuit Technology, the second compressor continues to work independently so that the temperature is maintained at -70 °C. This means that samples remain safely protected even if one circuit fails.
Are there any special standards or certifications?
The appliance complies with all current European standards for ultra-low temperature freezers. In addition, it complies with the F-Gas Regulation (EU 517/2014) and only uses environmentally friendly refrigerants with ODP = 0.
Which substances can be cooled with it?
From biological samples such as zoological tissue, enzymes or bacterial cultures through to vaccines, proteins and sensitive chemicals, almost any type of cold-sensitive material is suitable.
How quickly does the system cool down?
The powerful, low-noise compressors ensure rapid cooling. The exact speed depends on the quantity and initial temperature of the set samples.
Conclusion
This ultra-low temperature freezer combines high safety, energy efficiency and flexible application options so that even sensitive samples that require storage below -80 °C can be reliably stored. The combination of state-of-the-art touchscreen control, innovative double cooling circuit technology and high-quality insulation makes the appliance a particularly strong partner for laboratories, research facilities and the pharmaceutical industry.
