Shaker and rocker are ideal for almost any vessels from tubes through petri dishes and microtitre plates to conical flasks.Shakers are available with either an orbital action where the platform moves in a circular orbit or a reciprocal linear movement where the platform moves back and forth horizontally.An orbital action provides a swirling action on the samples,ideal for aeration. A linear shaker is more aggressive making it ideal for applications such as extractions. A see saw rocking action provides a wave motion in the samples, idea for washing.
