Many different drugs, bacteria, enzymes, viruses, tissue samples, and cell preparations, among other things, can be stored between -86°C and -20 °C (-123 °F and -4°F) in reliable ultra-low temperature freezers, also known as ULTs. These medical products are important laboratory equipment and are used for the long-term storage of extremely temperature-sensitive biological materials while preventing them from being damaged by suboptimal temperatures. It is for this reason that Ultra-Low Freezers are critical for the preservation of some of the most precious biologicals used in laboratory and clinical settings.
B Medical Systems is a global medical devices manufacturer and distributor of medical refrigeration, blood management and vaccine cold chain solutions with over 40 years of experience. Among its over 100 products in its portfolio, the company offers multiple Ultra-Low Freezers to store extremely thermosensitive vaccines, medicines and samples at temperatures ranging from -86°C to -20°C. These ULTs are ideal solutions for research institutes, hospitals, clinics, biorepositories, laboratories, and universities, to safely and reliably store their most precious biologicals. B Medical Systems’ Ultra-Low Freezers have been tested for ongoing performance and stability at temperatures as high as +43°C, showing dependability and solid performance even in the harshest environments.

B Medical Systems offers a wide choice of product sizes and features to meet any requirement.
When it comes to the integrity of the samples stored, the Ultra-Low Freezers' capacity to maintain homogenous air circulation - and hence their ability to maintain uniform temperature throughout the cabinet - is critical. B Medical Systems' Ultra-Low Freezers use an innovative cooling technology to keep the temperature stable and consistent throughout the cabinet. This, together with sealed gasket, an enhanced frame, superior overall insulation, and more, allows for the uniform temperature distribution required for a reliable storage environment and excellent sample protection.
For the cabinets to return to their optimal temperatures following door openings or defrost, a quick pull down is required. This is very important as it prevents samples stored inside to be exposed to the temperature differences which can sometimes reach over 100°C between the inner cabinet and the ambient environment. As various institutions will need to open their ULTs at various frequencies and for different durations, therefore potentially changing the inside temperature of the cabinet, these medical cold chain solutions need to be able to quickly reestablish their internal temperatures as fast as possible. With their superior technology, all of B Medical Systems’ Ultra-Low Freezers can do this effortlessly and rapidly, ensuring the safety of the products stored inside them. Moreover, to minimize air loss during door openings, these ULTs are equipped with internal doors which help the units maintain the cold air inside of them.
In the event of an unlikely breakdown or a power outage, the ability to maintain a safe temperature inside the cabinet for an extended period is critical for the stored specimens’ safety. The inner aluminum doors, polyurethane foam-insulated panels, and many other features of these ULTs help maintain the temperature inside the cabinet consistent by minimizing cold air loss while ensuring the least possible impact from the outside environment. B Medical Systems’ Ultra Low Freezers are therefore able to maintain the samples they store for extended periods of time, giving plenty of time for the researchers or healthcare workers to either fix the problem or transfer the samples to a backup medical cold chain solution.
The Ultra-Low Freezers from B Medical Systems also use natural green refrigerants to reduce their environmental impact while increasing their overall cooling efﬁciency, allowing these models to help reduce the vast energy consumption usually related to these types of products. The company’s ULT models are class II medical devices (EU MDR and US FDA), conform to EU F-Gas and US SNAP regulations, and the Energy Star certiﬁcation is also available on some of them.
B Medical Systems’ Ultra Low Freezers offer convenient data management through a 7 inches touch screen display and enables data export through the USB ports and SD cards. The company also offers reliable remote monitoring via °B Connected, a cloud-based monitoring solution. Furthermore, these solutions offer graphic displays of the temperature curves, integrated event and activity history of the units and are compliant to the technical controls of the 21 CFR Part 11 regulation (subpart A and B).
These models also offer remote monitoring capabilities via a Remote Monitoring Temperature Device (RTMD) which can track many functionalities 24/7, including the inner temperature and ambient temperature, lid openings and the product’s GPS position. This data is always accessible to the owner of these Ultra Low Freezers the RTMD is attached to, and will be able to receive automatic Email and SMS alarm notifications in case of any unwanted temperature deviations, creating a higher level of security for any vaccine, medicine or sample stored inside the units.
What to Look for in a Next-Generation ULT Freezer?
• Temperature set points ranging from -86°C to -20°C to store a wide range of samples.
• Uniform and stable temperature distribution inside the cabinet.
• Fast temperature recovery times
• Reliable Hold Over times
• Energy efficiency and sustainability
As you can see, there's a lot to consider when selecting an ultra-low temperature freezer for your laboratory or institution. However, it is critical to consider the points above when comparing these types of medical cold chain solutions as they could be the difference between ensuring the safety of your thermosensitive biologicals and having to dispose of important and valuable samples because they have been rendered unusable due to temperature excursions.
B Medical Systems is a global manufacturer and distributor of medical cold chain solutions with over 40 years of experience in this field.
