Stuart SB3 and SB2 Rotators by Cole Parmer are designed to provide controlled mixing and can be placed in heating and cooling incubators or cold store rooms temperature range  4°C to 40°C.  The rotation angle is operator adjustable with a scale to note the position to ensure repeatability. At one end of the scale, the horizontal position provides low levels of mixing, the vertical position ensures high levels of mixing, with variable mixing levels in-between. With the SB3 model, the rate of mixing can be set between 2 and 40 rpm, also included is a timer and digital speed display to reproduce results. The SB2 is the stripped-down rotator and offers a fixed rotating speed of 20rpm. Both models have an inbuilt spillage tray.

Suitable for general laboratory mixing, keeping biological samples in suspension, e.g. blood, aerating cultures.  Each model must be ordered with a tube holder for operation, range detailed below. It is possible to simultaneously use two tube holders on one rotator using the optional dual holder add on.
