Grain Size Analysis - Elabengineering

Grain Size Analysis (Pipette Method) is used to determine sub sieve particle distribution in a soil sample by mechanical analysis. This analysis expresses quantity proportions by weight of the various size particles present in the soil. It is recommended as a standard procedure to use dispersion agent to avoid flocculation. It consists of a sliding panel which moves up and down by means of a screw allowing Anderson pipette to get raised or lowered vertically. A sedimentation tube is held by a laboratory clamp provided on the stand below the pipette. The depth of immersion is measured by a scale graduated in mm at the side of the sliding panel
