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.

LINEAR SHRINKAGE MOULD AZA0850

The AZA0850 Precision Linear Shrinkage Mould from AZALAB is a compact and highly accurate laboratory instrument designed for determining the linear shrinkage of fine-grained cohesive soils in accordance with BS 1377-2. This test is a key component of soil classification and is especially important in identifying shrink–swell behavior of clays and expansive soils.

Linear shrinkage testing measures the reduction in length of a soil specimen upon drying, expressed as a percentage of its original length. The results provide valuable insight into soil expansiveness, volume stability, and suitability for foundations, pavements, and earthworks.

Manufactured from high-quality brass or stainless steel, the AZA0850 mould offers precise internal dimensions, excellent corrosion resistance, and a smooth polished finish for easy sample preparation and removal. Its robust construction ensures repeatable, reliable results even under high-frequency laboratory use.

MOTORISED SAND EQUIVALENT SHAKER AZA0861

The AZA0861 Motorised Sand Equivalent Shaker is a precision-engineered laboratory instrument designed to automate the agitation phase of the Sand Equivalent Test. It ensures uniform, repeatable shaking in full compliance with ASTM D2419, AASHTO T176, and IS 2720 (Part 37), eliminating operator variability associated with manual shaking. This shaker is an essential accessory for soil, aggregate, and construction material testing laboratories where accurate assessment of sand cleanliness and clay-like fines is critical.
Purpose & Function The Sand Equivalent Test evaluates the relative proportion of sand versus clay-sized or plastic fines in fine aggregates. During testing, the sample and calcium chloride solution must be agitated for a defined stroke length and rate. The AZA0861 automates this process using a controlled reciprocating motion, delivering consistent agitation that improves repeatability, reduces operator fatigue, and enhances overall test reliability.

PARTICLE SIZE SEDIMENTATION (HYDROMETER METHOD) AZA0857

AZA0857 – Particle Size Sedimentation Apparatus (Hydrometer Method) The AZA0857 Particle Size Sedimentation Apparatus (Hydrometer Method) from AZA Lab is designed for determining the particle size distribution of fine-grained soils, particularly silts and clays smaller than 75 microns. This method is widely adopted in soil mechanics, geotechnical engineering, civil construction quality control, and academic laboratories where accurate characterization of cohesive soils is essential. The hydrometer method is based on the sedimentation principle governed by Stokes’ Law, measuring changes in the density of a soil–water suspension over time. By recording hydrometer readings at defined intervals, the percentage of soil particles remaining in suspension is calculated, enabling precise determination of grain size distribution for fine soils beyond the practical limits of sieve analysis.

PLASTIC LIMIT SET AZA0848

The AZA0848 Plastic Limit Set is a standardized soil testing kit designed for the accurate determination of the plastic limit of fine-grained soils, in accordance with IS: 2720 (Part 5) and ASTM D4318. The plastic limit is a fundamental soil index property used in soil classification and in evaluating soil behavior under varying moisture conditions. This test kit is an essential component of geotechnical investigations, civil engineering projects, and soil mechanics laboratories, providing reliable and repeatable results in both laboratory and field environments. Purpose & Importance The plastic limit represents the lowest moisture content at which soil remains plastic and can be rolled into threads of 3 mm diameter without crumbling. Determination of this limit is critical for:
  • Soil classification (Atterberg limits)
  • Assessing workability and consistency
  • Evaluating shrink–swell characteristics
  • Supporting foundation, pavement, and earthwork design

SEMI AUTOMATIC CONE PENETROMETER AZA0852

The AZA0852 Semi Automatic Cone Penetrometer from AZALAB is a precision-engineered laboratory instrument used for determining the liquid limit and consistency characteristics of fine-grained soils. Designed to eliminate operator-dependent errors, this semi-automatic model ensures uniform cone release and repeatable penetration results, making it an ideal choice for geotechnical, civil engineering, and construction material testing laboratories. The apparatus conforms to IS 2720 (Part 5) and BS 1377 standards and is widely used for soil classification, foundation assessment, and settlement analysis. Its semi-automatic clutch-based drop mechanism allows the cone to penetrate the soil sample under controlled conditions for a fixed duration of 5 seconds, ensuring consistent and reliable test outcomes.

Principle of Operation

A soil paste prepared at known moisture content is placed in the sample cup. The standardized cone, attached to a calibrated weight, is released using the semi-automatic clutch mechanism, allowing free fall penetration into the soil. After the specified time (typically 5 seconds), the penetration depth is measured using a high-precision dial gauge. The moisture content corresponding to a penetration of 20 mm is considered the liquid limit of the soil, as defined in IS and BS standards.
