National Lab Thorbi Primus TPC7086DCC ultra-low temperature freezer
The National Lab Thorbi Primus TPC7086DCC ultra-low temperature freezer is ideal for laboratories in the pharmaceutical, chemical and biotechnology industries that require reliable and highly efficient storage of frozen samples. Thanks to its Double Cooling Circuit Technology, it offers a high degree of reliability, which makes it particularly attractive compared to many other ultra-low temperature freezers on the market. Similarly equipped products such as the [National Lab Thorbi Primus TPC5095DCC] ultra-low temperature freezer also ensure deep and stable cooling, but do not usually come close to the performance of this model in terms of volume and double cooling circuit design.
Performance features and special features
This model impresses with its sophisticated refrigeration technology and ease of use. At its heart is the Double Cooling Circuit Technology with two independently operating compressors. For everyday laboratory work, this ultra-low temperature device offers a temperature range of -40 °C to -86 °C as well as extensive options for recording and efficiently managing important measurement data. If you are looking for alternatives with almost the same control concept, the [National Lab ultra-low temperature freezer Thorbi Primus TPC3505DCC], for example, has a similar touchscreen user interface, but usually with a smaller usable volume.
- Temperature range: -40 °C to -86 °C, ideal for long-term storage of sensitive samples
- Climate class 4 (30 °C, 55 % HR), suitable for use in demanding working environments
- Generous usable volume: rounded stainless steel interior corners are available for the 696 liter net capacity
- Air-cooled condensation system for reliable performance and reduced maintenance
- High-pressure polyurethane insulation (CFC-free, ODP=0) with a density of 40 kg/m³ and 120 mm thickness for minimal cooling losses
- Double cooling circuit: If one unit fails, the other maintains -70 °C so that samples remain largely protected
- Comprehensive alarm system (visual and audible), including battery backup for the digital controller
In addition, the device impresses with durable materials such as galvanized, plastic-coated sheet steel for the outer body and AISI 304 stainless steel in the interior. The 5-inch graphic touchscreen enables precise settings with an accuracy of up to 0.1 °C. An integrated data logger as well as USB and RS485 interfaces offer comprehensive documentation and fast data evaluation.
Certifications and standards
Compliance with the European F-Gas Regulation (EU 517/2014) reflects the environmentally friendly refrigeration system. The use of natural, "green" refrigerants (HC) meets high safety and environmental standards. Typical quality standards in laboratories such as CE conformity and DIN regulations for safe and reliable refrigeration technology are also generally met by these appliances.
Concrete application examples
- Long-term storage of vaccines and biotechnological samples, where temperature fluctuations must be avoided at all costs
- Storage of sensitive forensic materials that must remain frozen for later analysis in order to maintain their integrity
- Structural investigations in pharmaceutical research, for example to test the stability of proteins and enzymes.
- Storage of temperature-sensitive raw materials in the chemical industry, for example pure solvents or reagents, so that they are available in perfect condition at all times.
Frequently asked questions (FAQ)
How is the desired temperature set precisely?
The temperature can be conveniently and precisely selected between -40 °C and -86 °C via the integrated 5-inch touchscreen. Thanks to a PT1000 sensor, the chest freezer maintains the temperature level to an accuracy of 0.1 °C.
Can I save my measurement data and alarm history?
Yes, the device has a USB port and an RS485 interface. You can use this to export and evaluate data. An integrated data logger also ensures complete documentation.
What happens in the event of a power failure
Double Cooling Circuit Technology ensures that the internal temperature is maintained for as long as possible in the event of a cooling circuit failure. In addition, the system has a battery backup to maintain alarms and the digital controller.
Do I have to defrost the freezer at short intervals?
Manual defrosting is required at certain intervals to remove layers of ice build-up and ensure consistent cooling performance. However, due to the extensive insulation and efficient cooling technology, the defrosting effort is moderate.
Conclusion
This ultra-low temperature freezer offers generous capacity, precise temperature control and a double cooling concept for maximum reliability. Thanks to extensive safety features such as visual and audible alarms and a powerful digital control and monitoring system, it is ideal for use in research, development and industrial laboratories. The robust workmanship and environmentally friendly refrigeration system round off the overall concept and make this model a reliable solution for the demanding storage of sensitive samples.
