IKA EUROSTAR 20 High Speed Overhead Stirrer

Category Overhead Stirrers
Manufacturer IKA
Country of manufacture the United States

Automatically adjusts the speed through microprocessor controlled technology. Safety circuits installed ensures automatic cut-off in an anti-stall or overload conditions. Continuous comparison of shaft speed to desired speed is maintained and variations are adjusted automatically. This guarantees a constant speed even with changes in viscosities of the sample.


  • Infinitely adjustable speed
  • Push-through agitator shafts
  • Overload protection
  • Short-term overload operation
  • Slim casing
  • Quiet operation
  • Error code display

Is the EUROSTAR 20 High Speed UL listed?

Yes, it is.


I am working with a volatile, flammable solvent. Are the EUROSTAR overhead stirrers suitable for use with flammable vapors?

No, they are not. To do so, they would need to carry an explosion-proof certification, which they do not have.


Can the EUROSTAR overhead stirrers be used in a clean room?

The EUROSTAR stirrers are not designed for clean room use.
