Air Jet Dispersion Tube

Alternative method for dispersing soil suspensions used in hydrometer method of testing sub-grade soils. Uses air bubbles to disperse soil samples. Comparative tests show the unique air jet action achieves better dispersion of clays with less degradation of soft particles like micas. Provides easier method, as samples are dispersed right in the sedimentation cylinder, eliminating the mess and sample loss from moving samples from one container to the other. Used by U.S. government agencies, State DOTs and consulting geotechnical engineers.
