IKA RW 28 Digital

The IKA RW 28 Digital Overhead Stirrer:  A powerful, mechanically controlled laboratory stirrer designed for highly viscous applications for quantities up to 80 litres (H2O).

A perfect partner to the ReactoMate Pilot Scale controlled laboratory reactors, it is suitable for intensive mixing for use in laboratories and pilot plants.

The stirrer comes equipped with a protection for overheating of the motor by means of self-locking temperature limiter. Additionally, to secure bowls, a stirring shaft protection and clamping fixture are optionally available.
