These flocculators are designed for repeatable conditions between samples and from run to run. Speed control with electronic feedback accurately maintains the rotational speed of the stainless steel paddles. Two preset programs allow routine speed and time parameters to be entered, stored in memory, and recalled or altered at any time.
