Description
RW 28 digital
Powerful, mechanically controlled laboratory stirrer designed for highly viscous applications for quantities up to 80 l (H2O). 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.
