The BenchMixer™ V2 provides a smooth, quiet, and effective mixing with Q-Drive™ technology. Depending on the vortexed vessel type, a unique reversible rubber head can be attached to the mixer in two orientations. The cupped surface head side is ideal for vortexing single tubes, and the dimpled surface side is excellent for multiple tubes or uniquely shaped vessels. Switching between the heads is a simple as flipping the mixing head over. The unit has a maximum speed of 3,200 rpm, allowing the mixer to instantly vortex even the large sample sizes, including filled 50ml tubes.
