Variable Speed Rotator

The TSB3/120V/60 is ideal for aerating cultures, keeping biological samples in suspension and for general mixing applications. The rotator can be used in incubators up to 60°C and in cold rooms down to 4°C. The rotator has a variable speed of 2 to 40 rpm for gentle rolling or vigorous missing of samples and the angle of rotation if fully adjustable, from horizontal for minimal mixing to vertical for full end-over-end mixing. A digital timer and speed display allow procedures to be accurately repeated for optimal results. A tray catches any spillage from the rotating tubes. A choice of six tubes holders are available to fulfill most applications. Holders must be ordered separately.
