GRAIN SIZE ANALYSIS (PIPETTE METHOD)
IS: 2720(part - IV) and BS : 1377.
This is for the determination of there sub sieve particle distribution in a soil sample by mechanical analysis. An analysis of this kind expresses quantitatively the proportions by weight of the various sizes of particles present in the soil. It is recommended as a standard procedure to use dispersion agent to avoid fluctuation.
The apparatus consists of a sliding panel which moves up and down by means of a screw allowing Anderson pipette fixed to it to be 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. Supplied complete with Anderson pipette 10ml. at the side capacity made from glass, and a sedimentation tube also of glass of 500 ml capacity and 50 Nos. Test forms.
