1. Introduction
The Model 440 Capillary Suction Timer (CST) consists of a digital timer, sample cell, and a specially selected filter paper composed of unidirectional fibers. Aqueous samples are placed in the sample cell, resulting in variable rates of water passing into the filter paper through capillary suction action.
The rates of filtration are dependent upon particle size, solids content, and settling rates of flocculation state. Thus, the instrument is adaptable for use as a control parameter for waste disposal facilities and for classification and qualification of soil types in geotechnical use, evaluation of soil/bentonite liners, and analysis of slurry trench fluids and drilling fluids.
The CST is ideal for use in the field as it operates on a single 9-volt battery which provides over 40 hours of use. A battery eliminator is supplied for laboratory use. The complete CST device consist of a timer unit, test head assembly with funnel, 9 VDC battery and battery eliminator (115 VAC), one box of filter paper, and instructions.
