Fixed board that floats of water bath

Fixed board that floats of water bath, it relates to a water bath fixed plate. The utility model discloses a solve present water bath and during the gas expansion, result in centrifuge tube cover to collapse out with floating the board in the centrifuging tube, slope easily when taking out, result in the problem that the sample intake. Fixed board that floats of water bath includes that high temperature resistant foamed plastic floats board, high temperature resistant foamed plastic apron, a plurality of centrifuging tube fixed orifices, joint portion and handle, high temperature resistant foamed plastic float the board and adopt hinged joint with high temperature resistant foamed plastic apron one end, the other end adopts joint portion to connect, a plurality of centrifuging tube fixed orifices equipartition set up on high temperature resistant foamed plastic floats the board, the handle setting at the upper surface of high temperature resistant foamed plastic apron. The advantage: one, is equipped with the
