Benchmark TubeRollers are designed for the gentle, thorough mizing of a variety of containers, includeing Vacutainers, bottles, test tubes, centrifuge tubes and roller bottles. Both models (5 roller and 10 roller) operate at a constant 38 rpm, chosen as the optimum speed fo rthe broadest range of mixing requirements.
As the roller mechanism rotates through each complete revolution, the right side of each roller is gently elevated about 0.5 in (13mm) and returns to the horizontal starting position. This additional, gentle up/down motion provides a "wave" effect and guarantees that the entire sample is subjucted to complete, thorough mixing, end to end. This built in tilt feature provides a level of homogeneous mizing uniformity that can not be matched by any stationary roller apparatus.
