The SB rotators give gentle but effective mixing, ideal for keeping biological samples in suspension e.g. blood, aerating cultures and for general mixing applications.

The rotators can be used in incubators up to 40°C and in cold rooms down to 4°C. The angle of rotation is fully adjustable with a scale to measure and reproduce the mixing angle, from horizontal for minimal mixing to vertical for full end-over-end mixing. An integral tray catches any spillage from the rotating tubes


The SB2 rotator has a constant speed of 20rpm


The SB3 has a digital timer and speed display allowing procedures to be accurately repeated for optimal results.

A choice of six tube holders is available to fulfill most applications. It is possible to use two tube holders simultaneously with our dual holder accessory.
