Six-Paddle Stirrer, 115-230 VAC, 50/60 Hz

Stirrer designed to meet ASTM standard method D 2035 for Coagulation-Flocculation Jar Test|Determine optimal chemical dosages for flocculation|Save expense by putting an end to unnecessary chemical waste. This six-paddle stirrer helps you determine the exact amount of alum or polymer necessary to trigger flocculationno need to add extra chemicals just to be sure. Stirrer design is based on method D 2035 (Standard Practice for Coagulation-Flocculation Jar Test of Water) in ASTM Standards: Section 11, Water and Environmental Technology Volume 11.02. Stirrer speed can easily be regulated from 0 to 300 rpm and is indicated on the convenient LCD readout. Stirrer includes six square B-Ker² beakers that stir up to six samples simultaneously. These two-liter beakers feature durable 1/4"-thick acrylic construction to ensure a constant sample temperature for consistent results. Unique beaker design minimizes sample swirl to reduce spillage during high stirring speeds; a conveniently located siphon allows you to draw sample without disturbing the floc at the bottom of the beaker. A built-in LED floc illuminator provides glare-free lighting to provide diffused lighting of samples. Stirrer measures 42"W x 14-3/4"H x 9-3/8"D (106.7 x 37.5 x 23.8 cm).
