  • Speed settings from 0 to 200 rpm, with standard 50 mm throw allows for optimal shaking conditions
  • Time can be set in seconds, minutes and hours
  • Separate LED displays allows shaking time and speed to be called up and changed during any procedure. Allows manual intervention without affecting the program
  • Optional breaks can be set into any program


  • Plastic housing improves resistance to corrosion.
  • Stable base plates mean that shakers can handle heavy loads up to 30 kg for long continuous operation.

Gerhardt offer two basic models of shaker. Together with the extensive range of accessories, these shakers easily satisfy the extensive requirements of chemical, biological, or microbiological research. Heavy loads are handled with the same ease as varying temperature or humidity conditions. Both models can handle loads up to 30 kg. Delivery of the basic model includes 4 vertical rods 150 mm long to accept the variety of attachments (spanner included for easy assembly), mains cable and an instruction manual.

Shaking frequency 20 - 200 min-1, amplitude 50 mm, time and speed can be programmed, shaking platform 540 x 370 mm, max. load 30 kg.

For all shakers we offer a large variety of accessories. .


Shaking the classic way

  • Mixing of liquids
  • Dissolve poorly soluble salts
  • Create emulsions
  • Homogenization of suspensions
  • Liquid/liquid extractions

Environemental analysis

  • Elute soils
  • Shaking of water samples
  • Dissolve contaminants of sewage sludge
  • Dissolve nutrients from substrates
