Decoloring shaker, mainly used for fixing the separation band of electrophoresis gel, shaking and shaking during Coomassie blue staining and decoloring, fixing, dyeing, and developing of silver nitrate staining, developing X-ray film in autoradiography experiment, Fixing, further processing of cellulose membrane after electric transfer, reaction and staining of antigens, molecular hybridization, cell culture, etc. can be used in all experiments where samples need to be shaken in solution. The instrument adopts imported motor suspension structure, stable rotation, extremely low noise, rotation speed can be adjusted arbitrarily, and continuous use.
