Health Care Logistics offers a solution to the settling of samples due to improper mixing, as well as repetitive strain injury due to constant manual shaking of tubes. The Tube Rocker gently rocks tubes in sizes 1.5 mL to 50 mL and at a tilt angle (24 rpm/30°) without the need for bands, straps, adapters, or hardware. The instrument is compact, enabling it to be easily placed on a lab bench, or within a refrigerator or laboratory incubator.
