National Lab ultra-low temperature freezer Thorbi Primus TPU7586DCC
The National Lab ultra-low temperature freezer is used in demanding laboratory environments to safely store sensitive samples, vaccines or other heat-sensitive substances at temperatures as low as -86 °C. Its Double Cooling Circuit Technology guarantees fail-safe operation, while other features ensure a high level of user convenience and precise control. Similar cooling concepts to the [National Lab ultra-low temperature freezer Maximus TPD6586DCC] also demonstrate the high safety standard for sensitive samples, but show the focus on long-term stability in continuous operation.
Detailed description
This precision cooling system covers a wide temperature range from -40 °C to -86 °C and uses a combination of vacuum insulation panels (VIP) and high-pressure polyurethane insulation to ensure minimal heat loss even with frequent door openings. Within its sturdy galvanized sheet steel housing, its interior is finished entirely in AISI 304 stainless steel, making it easy to clean and highly resistant to common laboratory chemicals. Odor- and bacteria-prone surfaces are prevented thanks to the rounded interior corners.
Of particular note is the refrigeration system, which uses environmentally friendly ("green") refrigerants (HC) and complies with the European F-Gas Regulation (EU 517/2014). Two independent compressor units act like a safety net: if one cooling circuit fails, the active circuit continues to reliably keep the interior at up to -70 °C. This makes the appliance ideal for all situations in which sensitive samples need to be secured around the clock, for example in pharmaceutical research or forensic laboratories.
In everyday use, the Thorbi Primus ultra-low temperature chamber proves to be a reliable partner not only thanks to its quiet operation, but also because of its clear operation. A digital touch display, which is equipped with a 5-inch graphic touchscreen, makes it easy to enter the desired temperature and other parameters. The USB interface also enables temperature data to be exported quickly. With its internal data logging and back-up battery for the digital controller, the system ensures constant monitoring and complete documentation of the cold chain.

Certifications and standards
Thanks to CFC-free insulation, biodegradable refrigerants and 100% testing of all condenser units in helium chambers, the freezer meets all current laboratory standards. In the event of a fault, visual and acoustic signals are triggered to warn staff in good time. The cabinet also complies with common tests for laboratory equipment in its class to ensure a high level of occupational safety.
Examples of use
- Long-term storage of vaccines and virus strains in research-based pharmaceutical companies.
- Safe storage of sensitive reference materials for quality control in production plants.
- Storage of biological samples (e.g. cells, tissue) for university institutes.
- Use in clinical research for the preservation of particularly temperature-sensitive medicines.
Frequently asked questions
How quickly is the target temperature reached
?
The efficient combination of double refrigeration circuit and high-quality insulation generally leads to rapid cooling - however, exact times depend on factors such as load quantity and ambient temperature.
Can the cabinet maintain the temperature in the event of a power failure?
The ultra-low temperature enclosure uses its twin compressors and high-performance insulation layer to keep the temperature stable for as long as possible, even in the event of a fault. Temperature monitoring is also supported by a backup battery and alarm signals.
What maintenance work is required on a regular basis?
In addition to occasional defrosting, cleaning the interior surfaces and replacing the door seal when it is worn, it is advisable to check the compressors regularly. Thanks to clear alarm signals, the appliance remains reliable in the long term.
Is the data recording sufficient for audits?
The integrated logger function meets common audit requirements and enables complete documentation. The USB interface allows the recorded data to be quickly transferred to an external storage medium.
Can I connect additional sensors?
The RS485 interface offers a suitable option for connecting external measuring devices or monitoring systems. This makes the documentation even more comprehensive and meets high traceability requirements.
Conclusion
This cooling unit is a reliable solution for laboratories that rely on uncompromising operational reliability and precise temperature control. The combination of two independent refrigeration circuits, a high-performance insulation layer and comprehensive monitoring functions ensure that stored samples remain safely protected. The contrast to comparable systems makes it clear that this cabinet focuses on process safety and user-friendliness thanks to high-quality materials and intelligent alarms. If you need an ultra-low temperature freezer with high capacity and a modern safety concept, this model will provide lasting support.
