When it comes to ultra-low temperature storage, one factor is of paramount importance: the reliable protection of samples over long periods of time. Memmert ULT freezers have been specially developed for this purpose. They combine constant, precise temperature control with integrated safety features and an energy-efficient design for continuous operation.
In many life science and clinical applications, the storage of biological materials is the longest part of the operating process. Samples must be kept stable and protected for days, weeks or even years. Reliably maintaining defined and uniform conditions is therefore not just a technical detail, it is a critical factor for success.
Sensitive samples can be endangered by even the slightest temperature deviations, which is why these freezers ensure that the interior conditions are always stable and homogeneous, regardless of the position of the sample.
The powerful cooling system with two cascaded compressors enables fast cooling. Insulated stainless steel outer door and 2 inner stainless steel doors. Optional versions with 3, 4, 5 or even 6 inner doors are also available. Each unit is equipped with a door opening sensor and a PT1000 sensor for temperature control.
With an intuitive 7-inch touchscreen interface, visual and audible signals, LAN and USB connectivity. Can be integrated into the myChamber system, which allows real-time monitoring of the unit from a computer, tablet or smartphone.
Standard version: Cooling system with two cascaded compressors for reliable low temperature performance
Eco version: Cooling system with two cascaded inverter compressors for precise temperature control and high energy efficiency.
