A tube rocker is a compact laboratory device designed to provide gentle and uniform agitation of samples contained in tubes. It operates using a rocking or see-saw motion, which ensures thorough mixing without causing sample damage.

Tube rockers are commonly used for applications such as blood sample mixing, gel staining, and molecular biology workflows.

The platform typically includes a grooved rubber mat that securely holds tubes in place, eliminating the need for straps or clamps.
