GRAIN SIZE ANALYSIS (PIPETTE METHOD):

AS PER IS: 2720 (Part - IV) & BS: 1377.

Introduction:

• This is for the determination of their 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 flocculation.

General Description and Specifications:

• 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 10 ml. at the side capacity made from glass, and a sedimentation tube also of glass of 500 ml capacity and 50 Nos Test forms.
