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: e..g. the flow the tool causes in the medium, the tools adequate field of application depending on the speed range, and the execution ot the tool according to the viscosity it is destined for.
Application examples:
1. Gasing of liquids < 500 mPa s:Radial Flow Impeller
2. Homogenizing and suspensing in liquids < 500 mPa s: Propeller-Type or Blade Impellers
3. Medium with a viscosity > 500 mPa s: Anchor-Type Impeller, Blade Impeller BR 13 or inoJET®
4. Stirring gel: inoET®
Please ensure that for radial flow, blade, half-moon and inoJET® impellers the beaker size and position of your impeller complies with the guidelines below to accomplish superior mixing results: Operational guidelines:
Position of the stirring tool
- In center
- Distance to the bottom (h3/d2): 0,3
- Ø Vessel (h1/d1): 1,0
- inoJET® Øratio (d2/d1): 0,4 - 0,6
Circumferential speed
- 3 - 15 m/sec: Radial Flow Impeller
- 2 - 5 m/sec: inoJET®, Blade and Anchor-Type Impellers
