MLM4-JARMODULE

Configuration: It has long been accepted that the square sample jar configuration is greatly superior to a cylindrical beaker for all coagulation and flocculation jar testing. Despite the higher initial cost, this type of jar is almost universally used by those requiring accurate, reproducible, and meaningful results from jar test procedures.

Material: ECE floc jars are fabricated from crystal-clear, colorless acrylic sheet. This allows far better visual observations of samples than is possible with the thin-wall, blue-tinted, injection-molded jars that are sometimes used for this type of work. The thicker wall of the ECE jars also results in less sample temperature variation during a jar testing run.

Capacity: MLM4 ECE floc jar module is 4 x 500mL jars connected together.

Calibration marks: All jars have calibration marks showing the 500 mL line.

Improved sampling arrangement: The old sampling arrangement consisting of a rubber stopper, glass tube, flexible tube, and tubing clamp (or some similar configuration) has been eliminated.

The stopcock is inserted directly into a fitting threaded into the wall of the jar, and can be removed with a quarter turn. If subsurface sampling is not required for a particular jar test run, the stopcock can be replaced with a cap, to make jar handling a little easier and to reduce risk of damage to the stopcock. This system eliminates the possibility of accidental spillage resulting from the stopper being dislodged or the glass tube being broken, ensures reproducible sample withdrawal rates, and is much more compact and convenient. It has proved to be vastly superior to the old rubber stopper based configuration in every way.
