AL30, AL40 & AL50

Flocculation testers are designed for a range of applications – such as testing the efficiency of flocculation or precipitation agents. The AL40 model with 4 stirring places and the AL50 model with 6 stirring places are fitted with an illuminated back panel for glare-free observation of the samples and are suitable for laboratory use.

The flocculation tester AL30 with 4 stirring places is primarily designed for field use. The 4 stirring points are arranged in a circle around a lamp making it easier to observe the flocculation process. State-of-the-art technology ensures maximum operating convenience and makes the unit maintenance-free. The main features of the laboratory jar testers are the continuously variable stirring speed, the digital display of stirring rpm, the timer function, the illuminated back panel, and the height adjustment option for the stirring blades during operation.

AL30 requires 1000 ml beakers of low form. AL40 and AL50 require 1500 ml beakers of low or high form. The beakers are not included.
