GRAIN SIZE ANALYSIS (PIPETTE METHOD) AZA0856

The AZA0856 Grain Size Analysis (Pipette Method) Apparatus from AZA Lab is a precision testing setup used for determining the distribution of fine soil particles such as silt and clay. It is widely used in geotechnical engineering, civil construction quality control, soil mechanics research, and academic laboratories, particularly where conventional sieve analysis is ineffective for particles finer than 75 microns. This apparatus is designed for the mechanical analysis of sub-sieve soil particles, expressing quantitatively the proportion by weight of various particle sizes present in a soil sample. The pipette method, based on sedimentation principles and Stokes’ Law, provides accurate and repeatable results for fine-grained soils. The system consists of a sliding vertical panel operated by a precision screw mechanism, allowing an Anderson pipette to be raised or lowered accurately. A sedimentation tube is held securely below the pipette using a laboratory clamp. The depth of immersion is measured using a millimeter-graduated scale mounted alongside the sliding panel. The apparatus is supplied complete with a 10 ml Anderson pipette, a 500 ml glass sedimentation tube, and test form pads, conforming to standard laboratory practices.

The apparatus is essential for determining Maximum Dry Density (MDD) and Optimum Moisture Content (OMC) for soils used in heavy-duty pavements, airfield runways, embankments, dams, and foundations, where higher strength and durability are required.
Purpose of Test The Modified Proctor Test applies significantly greater compactive effort compared to the Standard Proctor test. The results are used by engineers to:
    • Specify target field compaction densities
    • Control moisture during earthwork
    • Ensure long-term stability and load-bearing performance
