Vortex Mixer

A vortex mixer, or vortexer, is a simple device used commonly in laboratories to mix small vials of liquid. It consists of an electric motor with the drive shaft oriented vertically and attached to a cupped rubber piece mounted slightly off-center. As the motor runs the rubber piece oscillates rapidly in a circular motion. When a test tube or other appropriate container is pressed into the rubber cup (or touched to its edge) the motion is transmitted to the liquid inside and a vortex is created. Most vortex mixers are designed with 2 or 4-plate formats, have variable speed settings ranging from 100 to 3,200 rpm, and can be set to run continuously, or to run only when downward pressure is applied to the rubber piece.


  • Gentle to Vigorous Mixing
  • Chemically Resistant Body
  • Various heads can accommodate most shapes of test tubes, beakers, Eppendorf, micro tubes, flasks and other container.
  • Unique design of center of gravity to stabilize mixer free from
  • Various speed control to the maximum of 3200rpm, provided gentle or vigorous vortexing for your mixing requirements.
  • Some model features 4 interchangeable mixing head, i.e. snap on the 25.4mm diameter rubber cup head for conventional single tube mixing, or additional 3 diameter platform pads for multiple tubes for Eppendorf tubes, micro-plate of 96 wells, and also flask mixing.
  • 2-mode operation features “TOUCH” for intermittent operation, or “SWITCH” activated operation at the flip of a switch for continuous mixing.
  • Stirring intensity can be controlled in “TOUCH” mode by applying the pressure to the mixing pad.
  • User-friendly design capable of sustaining to prevent mixer from slipping and creeping due to the vibration.
