IKA RW20dzm.n Mechanical Overheadstirrer

IKA RW 20 DZM.n Mechanical Top Stirrer with Speed ​​Indicator

The IKA RW 20 DZM.n is a robust mechanical top stirrer designed for mixing and stirring liquids and viscous media in laboratory and research environments. Thanks to the powerful drive, two mechanically switchable speed ranges, and clear speed indication, the stirrer is suitable for a wide range of mixing applications.

The RW 20 DZM.n has a maximum stirring capacity of 20 liters (H₂O) and a continuously adjustable speed from 60 to 2,000 rpm. The device is suitable for media with a viscosity of up to 10,000 mPa·s and delivers a maximum torque of 150 Ncm to the stirring shaft.
