The FP4/JLT4/JLT-6 and FC-6S  Jar test / Flocculator is designed both for optimizing the dosing of coagulants for separating pollutants in wastewater treatment plants thanks to the laboratory results obtained using the so-called Jar Test, and for running toxic substance leaching tests on solid wastes to be sent to the dump.

The multiple stirrers with reproducible stirring speeds allow standard conditions for the tests to be adopted, a basic requirement in order to obtain reliable results.

The sample being examined can be backlit using a special switch found on the front panel making for easier readings.

The instrument has an ergonomic design and the control panel is tilted for easier parameter settings and readings. The rotation speed can be programmed from 10 to 300 rpm with 1 rpm intervals and the time remaining can be set to hours or minutes.
