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.

The ES-20 is a compact bench–top Shaker–Incubator used for mixing of biological liquids as well as for incubation and cultivation of biological liquids according to the operator set program

Applicable for storing wholeblood, medicines, biological products and other laboratory products that need to be stored at 4℃. Suitable for the storage of blood and blood articles in areas that have power shortages.

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.

A-12, adapter for work with tubes which are 12 mm in external diameter.
