LN2 backup cooling system is an independent refrigeration system for a ULT freezer. When there is a loss of power or the temperature of the freezer rises to the high alarm set point, the LN2 backup system can be automatically activated to inject LN2 into the chamber to maintain the freezer temperature. The backup system operates on a rechargeable battery when there is a loss of main power.

Features

● Interlocked design to turn off the LN2 injection when the door is opened

● Protection circuit to prevent over-charging battery

● Light weight and portable design, suitable for installation on top of a freezer

● Alarm functions to include low battery and sensor error

After the samples become freeze-dried preparations, they are more stable, especially for high temperature sensitive drugs, and most of them can be transported and stored at 0-4℃ or even normal temperature after freeze-dried, so the transportation and storage cost and inactivation risk are greatly reduced. Compared with traditional drying methods, the bioactive materials can restore their pre-freeze-dried conformation and biological function after redissolution. Therefore, freeze-drying is the safest method with the least impact on the properties of the drying materials.

Personal multi-channel bioreactor RTS-8 Plus

RTS-8 plus is a personal bioreactor that utilizes patented Reverse-Spin® technology that applies non-invasive, mechanically driven, low energy consumption, innovative type of agitation where cell suspension is mixed by the single-use falcon bioreactor tube rotation around its axis with a change of direction of rotation motion resulting in highly efficient mixing and oxygenation for aerobic cultivation. Combined with a near-infrared, fluorescence and luminescence measurement systems, it is possible to register cell growth kinetics, pH and O2 non-invasively in real time. For pH and O2, innovative single-use sensor spots are used inside the tubes.
