Benchmark TubeRoller with 10 rollers. Simultaneous roll & tilt with a fixed speed of 38rpm at a tilt angle of +/- 5°. Accepts vessels with diameters from 8mm to 200mm. Spacing between rollers is 5mm. 115V. **2 year warranty**

Benchmark TubeRollers are designed for the gentle, thorough mixing of a variety of containers, including Vacutainers™, bottles, test tubes, centrifuge tubes, and roller bottles. Both models feature variable speed control (2-80 rpm), suitable for the broadest range of mixing applications.

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 subjected to complete, thorough mixing, end to end. This built-in tilt feature provides a level of homogeneous mixing uniformity that cannot be matched by any stationary roller apparatus.

From blood collection tubes to roller bottles, Benchmark TubeRollers are the ideal choice for research, clinical laboratories, and doctors’ offices.
