Heidolph PR33 RVS omringde propellerroerder

Propeller-Type Impeller

• These impellers are recommended for applications which require average or high speed
• For mixing tasks with medium or high viscosity
• Excellent mixing properties for homogenization and suspensions
• These models create an axial flow

Selection parameters

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 suspending 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® impellers the beaker size and position of your impeller complies with the shown guideline to achieve superior mixing results
