Rotators
Mixing by rotation is more vigorous than a roller mixer, typically the sample, in either tubes or bottles, are turn end-over-end. Rotators can be based on a rotisserie type design whereby a single axis is rotated and samples are attached to this by a variety of different methods. Speed adjustment is available in both types to alter the severity of the mixing action. Ideal for aerating cultures, keeping biological samples in suspension and for general mixing applications including smaller samples held in 1.5ml micro tubes.
Stuart Rotator SB2 & Stuart Rotator SB3

The SB rotators give gentle but effective mixing, ideal for keeping biological samples in suspension e.g. blood, aerating cultures, keeping biological samples in suspension and for general mixing applications.
The rotators can be used in incubators up to 60°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.
A choice of six tubes holders are available to fulfill most applications. It is possible to use two tube holders simultaneously with our dual holder accessory.

Rotator drive unit
Built in timer
Variable speed control 6 to 60rpm
The STR4 rotator drive unit is used in conjunction with a wide range of drums designed to take different sizes and types of vessels. The five drums are designed to give different mixing actions and are listed on pages 62 to 64.
Speed of rotation is variable from 6 to 60rpm for a range of mixing applications.
For added convenience a built in analogue timer can be set from 10 to 60 minutes. Alternatively the unit can be set for continuous operation.
Rotation speed: 6 to 60rpm
