Ultra low freezer
Safe long-term storage of samples in the ultra low freezer
In pharmaceutical technology and biotechnology, valuable medical and biological samples and materials often have to be preserved at extremely low temperatures up to -86 °C for anything from several weeks to a few years. An ultra low freezer can be relied upon to store these samples and materials for prolonged periods of time with absolutely no problems at all. The cooling system used in an application of this nature must be absolutely safe and reliable. Something going wrong may not only lead to the loss of valuable samples, expensive reagents, or entire research results but also significant amounts of time and money. Reputations can also suffer.
Maximum reliability and numerous alarm options
In recent years, manufacturers have continuously improved the failure probability of units by delivering numerous ongoing developments. Integrated functions and alarm forwarding via e-mail are very helpful, in particular overnight and at weekends. Data logger functions, which enable cooling conditions to be tracked precisely and operating data to be analyzed and logged, have also been introduced. BINDER uses a multi-stage safety concept in its ultra low freezer, for example. Personalized access control protects the samples against unauthorized access. The integrated log memory seamlessly documents every opening. By managing users in this way, samples can be more effectively protected and proper handling can be monitored.
Saving space and energy
The optimized footprint of an ultra low freezer is also highly significant. As space is usually at a premium inside laboratories, the ultra low freezer must combine maximum usable space with a footprint that is small as possible. The units must also be energy efficient.
An ultra low freezer should be easy to maintain, clean, and operate. This saves time, shortens access times, and cuts energy costs. An easy mechanism for opening and closing the doors is also important for removing samples.
Maximizing user-friendliness and energy efficiency were of utmost importance when developing the BINDER ultra low freezer. The door opens automatically at the touch of a button, the air filter can be replaced without using tools, and the defrosting kit makes defrosting quick and easy. Large vacuum heat-insulating panels inside the housing reduce energy consumption and provide optimum insulation. A two-stage refrigeration cycle can be relied upon to maintain the extreme temperatures. The separate interior zones also ensure improved cold stabilization when the door is open.
