  • These impellers are recommended for applications which require average speed
  • For mixing tasks with little or average viscosity
  • With collapsible blade for narrow neck vessels

Precise working with an overhead stirrer depends on the right choice of the stirrer tool. When choosing a stirrer tool you have to consider its different characteristics and their effects. For example, the flow which the tool causes in the medium, the tool´s adequate field of application depending on the speed range, and the execution of the tool according to the viscosity it is destined for

Application examples:
  • Gassing of liquids
  • Homogenizing and suspending in liquids
  • Medium with a viscosity > 500 mPa s: Anchor-Type Impeller, Blade Impeller BR 13, VISCO JET®
  • Stirring of gel: VISCO JET®

Please ensure that for radial flow, blade, half-moon and VISCO JET® impellers the beaker size and position of your impeller complies with the shown guideline to achieve superior mixing results
