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 < 500 mPa s: Radial Flow Impeller
Homogenizing and suspensing in liquids < 500 mPa s: Propeller-Type or Blade Impeller
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® impeller the beaker size and position of your impeller complies with the guidelines below to achieve superior mixing results

  • In center
  • Distance to the bottom (h3/d2): 0.3
  • Diameter vessel (h1/d1): 1
  • VISCO JET® Ø ratio (d2/d1): 0,4 - 0,6


Circumferential speed

  • 3 - 15 m/sec: Radial Flow Impeller
