For the separation and purification of samples of cells, macromolecular proteins, blood, body fluids, DNA/RNA, plasmids, bacteria and viruses.
Sterile TPP TubeSpin® Bioreactor vessel, 50 ml, with pH and O2 sensor spots, 1 pce.
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.
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
