National Lab Thorbi Primus TPU4086DCC ultra-low temperature freezer
The National Lab Thorbi Primus TPU4086DCC ultra-low temperature freezer offers laboratory professionals a reliable solution for highly sensitive samples that need to be stored at extremely low temperatures. Thanks to the Double Cooling Circuit Technology, this model is characterized by a particularly high level of reliability, which sets it apart from many competing devices on the market. Users who specialize in similar freezers are often also interested in models such as the [FrosterTech UltraFreeze 90], which covers similar temperature ranges and has proven itself in demanding laboratory environments.
Performance features and areas of application
This ultra-low temperature freezer is tailored to the requirements of research facilities, biotechnology laboratories, pharmaceutical companies and medical facilities. It can hold samples of vaccines, enzymes or sensitive cell cultures and store them below -80 °C for long periods. This makes it ideal for:
- Long-term storage of biological samples, such as antibodies or cell lines.
- Pharmaceutical research in university laboratories and clinics.
- Biotechnological applications, particularly for enzyme tests or sample preparation.
- Medical facilities that need to store sensitive medical samples, such as blood plasma, safely and stably
Similarly equipped solutions such as the [FrosterTech UltraFreeze 90] are convincing in laboratories with high safety requirements. In comparison, the device described here has two independently operating cooling circuits that can continue to maintain -70 °C if one system fails.
Technical highlights
To give professionals a quick overview, here are the most important technical features:
- Temperature range: -40 °C to -86 °C
- Gross capacity: 414 liters, net capacity 400 liters
- External dimensions (WxDxH): 846 x 975 x 1997 mm
- Internal dimensions (WxDxH): 490 x 619 x 1300 mm
- Insulation: Vacuum insulation panels (VIP) and high-pressure polyurethane, CFC-free
- Door: 1 full door with lock and 4 additional inner doors
- Interface: RS485 and USB
In addition to these main points, the appliance has a whole range of other practical features. The construction of the outer housing is made of galvanized sheet steel with a plastic coating, while the interior is made of robust AISI 304 stainless steel. The rounded interior corners are easy to clean and therefore offer high hygienic standards. A door sensor is integrated for safe handling and the door seal can be easily replaced without having to carry out complex work.
The integrated data logger can be read on the 5-inch graphic touchscreen and saves all temperature curves for later analysis. A USB port allows the data to be downloaded quickly in CSV format. Thanks to the built-in PT1000 temperature sensor, the controller achieves an accuracy of up to 0.1 °C. There is also a backup battery for the digital controller, which ensures alarms and other protective functions.
Safety and standards
Double Cooling Circuit Technology ensures that the ultra-low temperature freezer can continue to operate at -70 °C, even if one of the two compressors should fail. This offers a significant advantage for high-quality samples where temperature fluctuations could lead to a loss of quality. In addition, the appliance works with natural, environmentally friendly refrigerants (R600a and R1150) and therefore complies with the European F-Gas Regulation (EU 517/2014). Thanks to a 100% test in helium chambers, each appliance is checked for any leaks.
Examples of use
- Long-term storage of vaccines in biotechnological and pharmaceutical research facilities.
- Safe storage of sensitive human samples such as blood plasma or serum in hospitals and laboratories.
- Freezer storage of enzymes or proteins for university research purposes.
- Stability tests at extreme sub-zero temperatures in quality assurance laboratories.
Thanks to its robust design, high safety standard and user-friendliness, this device is predestined for numerous applications in everyday laboratory work.
Frequently asked questions
How is the temperature controlled?
The temperature is controlled via a digital controller with touchscreen. Set values can be set precisely here. The display on the 5-inch graphic monitor is clear and intuitive to use.
What alarms are available
A wide range of visual and audible alarms indicate problems in the event of temperature deviations, door openings or power failure. This minimizes the risk of sample loss.
Is external temperature monitoring possible?
Yes, the RS485 and USB interfaces enable external monitoring. The integrated data logger also saves power and temperature data for later analysis.
What are the maintenance requirements?
The compressors are quiet and fully hermetically sealed. Manual defrosting should be carried out at regular intervals. Otherwise, only routine checks of the door seals and cooling system are required.
What safety precautions are recommended
In addition to the standard alarm functions, we recommend connecting the refrigerator to an uninterruptible power supply and using the built-in data logger for complete documentation.
Summary
The Thorbi Primus TPU4086DCC with Double Cooling Circuit Technology impresses with its high reliability, precise digital control and extensive protective functions. It offers the optimum combination of reliability, simple operation and environmental friendliness, particularly in the field of biotechnological research, the pharmaceutical industry and medical facilities. The generously dimensioned insulation, the efficient door concept and the integrated data logger functions ensure maximum safety and constant storage temperatures. With its large usable volume and robust design, this appliance is an excellent solution for all laboratories that need to deep-freeze sensitive samples or materials over an extended period of time.
