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.
HEAVY COMPACTION TEST AZA0865
The AZA0865 Heavy Compaction Test Apparatus from Azalab is designed for performing the Heavy Compaction Test, commonly known as the Modified Proctor Compaction Test. This test establishes the relationship between moisture content and dry density of soils under high compaction energy, simulating field conditions achieved by modern heavy compaction equipment.
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
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.
PLUMMET BALANCE AZA0862
The AZA0862 Plummet Balance is a specialized laboratory apparatus designed for determining the specific gravity of fine-grained soils, particularly clays and silts that are difficult to test using conventional pycnometer methods. It is widely used in geotechnical engineering, soil mechanics laboratories, and construction quality control applications.
Manufactured by Azalab, the instrument complies with ASTM D854 and IS 2720 (Part 3 / Sec 1) standards and provides rapid, repeatable, and reliable results for dispersed soil samples commonly used in sedimentation, pipette, and hydrometer analyses.
Working Principle
The plummet balance method determines the specific gravity of soil solids by measuring the apparent weight of a suspended plummet immersed in a soil–water suspension. The balance pointer directly indicates the percentage of soil in suspension via a calibrated scale, eliminating lengthy calculations.
A rack-and-pinion height adjustment allows the plummet to be positioned at the required depth. The percentage of soil in suspension is read directly from the graduated scale, making this method faster and more user-friendly than traditional sedimentation calculations.
The set is supplied with a temperature correction chart relating the constant K to suspension temperature for soils with specific gravity ranging from 2.4 to 2.8, facilitating accurate application of Stokes’ law.
POCKET PENTROMETER AZA0869
The AZA0869 Compact Pocket Penetrometer from Azalab is a field-ready instrument designed for rapid estimation of unconfined compressive strength (UCS) and shear strength of cohesive soils. Fully compliant with ASTM D1558 and ASTM D2573, it enables engineers, geologists, and site inspectors to quickly assess soil consistency and short-term stability without the need for laboratory equipment.
Widely used in foundation evaluation, trench wall inspection, and field soil classification, the AZA0869 delivers immediate, reliable results for clays and silts during preliminary geotechnical assessments.
Applications
- Estimation of UCS and shear strength of soft to stiff cohesive soils
- Field classification of soil consistency

The instrument employs a calibrated, spring-loaded plunger to measure penetration resistance directly (0–40 kg range). Two graduated stems allow accurate tracking of penetration depth, while a comprehensive set of interchangeable needle tips enables testing across a range of soil densities and particle characteristics.
Applications
- Field assessment of soil compaction
- Estimation of optimum moisture condition
- Subgrade, fill, and trench inspection
- Construction quality control checks
- Geotechnical and educational field investigations
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.
STANDARD COMPACTION TEST AZA0863
The AZA0863 Standard Compaction Test Apparatus from Azalab is designed to perform the Standard Proctor Compaction Test, a fundamental geotechnical laboratory procedure used to determine the Maximum Dry Density (MDD) and Optimum Moisture Content (OMC) of soils. These parameters are essential for ensuring proper soil compaction in the construction of roads, embankments, foundations, and other earth structures.
This apparatus simulates light compaction effort typically applied in the field and provides reliable, repeatable results for laboratory quality control and design verification.
Purpose & Principle
The Standard Compaction Test establishes the relationship between soil moisture content and dry density under a standard compactive effort. Soil samples are compacted in layers within a cylindrical mould using a specified hammer weight and drop height. By testing at varying moisture contents and plotting a compaction curve, the MDD and OMC are obtained.
