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.

SOIL CONE PENETROMETER AZA0851

The AZA0851 Precision Cone Penetrometer from AZALAB is a high-accuracy laboratory instrument designed for determining the liquid limit of fine-grained soils using the cone penetration method. The apparatus fully complies with IS 2720 (Part 5) and ASTM D4318, making it suitable for standardized soil classification and geotechnical investigations.

This method is widely preferred in modern soil mechanics laboratories due to reduced operator dependency and higher precision.

Principle of Operation

A soil paste prepared at a known moisture content is placed in the sample cup. The stainless steel cone, of specified mass and angle, is allowed to penetrate the soil freely for 5 seconds. The depth of penetration (up to 20 mm) is measured using a precision depth gauge. The moisture content corresponding to 20 mm penetration is defined as the liquid limit of the soil.

Standards Compliance

  • IS 2720 (Part 5) – Determination of liquid and plastic limits
  • ASTM D4318 – Liquid Limit, Plastic Limit, and Plasticity Index of Soils
