Roller mixers are ideal for gentle mixing at a steady even rate and ideal mixers to prevent sedimentation of samples. They consist of a number of motor driven rollers which rotate at either a fixed or variable speed. When the samples are placed between the rollers in tubes or bottles, they are gently rolled. A rocking action is also applied whereby the rollers are raised and lowered at one end during rolling. This increases the effectiveness of the mixing.

Applications: Mixing of blood samples, viscous samples, where minimum aeration is required or for aiding de-frosting of samples.
