Flocculation Jar Tester A laboratory tool called a flocculation jar tester is used to calculate the ideal dosage of coagulants, also known as flocculants, for the treatment of wastewater and water. Larger flocs are created by the process of flocculation, which makes it easier to filter or sediment the liquid's particles. Usually including numerous stirring settings, a flocculation jar tester enables the testing of multiple samples simultaneously under different conditions. Shop online at labtron.us
