The rotators will maintain integrity in incubators up to 60°C and in cold rooms down to 4°C. Angle of rotation can be fully adjusted plus there is a scale that can be used to measure as well as reproduce the angle of mixing, from horizontal used for minimal mixing and vertical for full end –over-end mixing. The integral tray will catch the spillage for rotation. Additional features include choice of tube holders to hold a number of different sized tubes, SB2 comes with fixed 20rpm speed, Rotators, SB2, SB3 and SB3 comes with adjustable speed between 2 and 40rpm.
