EXTRACTOR FRAME UNIVERSAL (SCREW TYPE) AZA0892
The AZA0892 Universal Extractor Frame (Screw Type) from Azalab is a robust and reliable apparatus designed for the safe, controlled extraction of soil samples from laboratory molds and field compaction cylinders. It is an essential tool for geotechnical laboratories and civil engineering testing facilities where preservation of sample integrity is critical to accurate test results.
Engineered with a manual screw-type loading mechanism, the AZA0892 applies a smooth, progressive extraction force, allowing soil specimens to be removed without cracking, crumbling, or altering their compaction characteristics. This controlled action is particularly important for samples prepared for Proctor, Modified Proctor, and CBR testing, where specimen disturbance can significantly affect density and strength measurements.
Description
Key Advantages
Screw Type Controlled Extraction
The precision screw mechanism enables gradual force application, ensuring gentle and uniform sample removal while minimizing disturbance.
Universal Mold Compatibility
Designed to accommodate a wide range of standard laboratory and field molds, reducing the need for multiple dedicated extractors.
Preserves Sample Integrity
Maintains the original density, structure, and moisture condition of the specimen, improving the reliability of subsequent testing.
Heavy-Duty Construction
Manufactured from robust, laboratory-grade steel to withstand continuous professional use.
Efficient Laboratory Workflow
Simple manual operation streamlines sample preparation, especially in high-volume testing environments.
Compatible Molds and Applications
-
Standard Proctor molds (typically 100 mm / 4 in)
-
Modified Proctor molds (typically 150 mm / 6 in)
-
CBR molds
-
Field density compaction cylinders and cones
Used extensively in:
-
Compaction and density determination
-
CBR testing
-
Strength and deformation studies
-
Quality control of earthworks and pavement layers
Construction and Design
The AZA0892 consists of a stable steel base, a vertical screw with hand wheel, and interchangeable top platens/adaptors to suit different mold sizes. The mold is securely positioned within the frame, and rotation of the hand wheel steadily pushes the soil specimen out of the mold with full operator control.

INFRARED MOISTURE METER AZA0875
The AZA0875 Infrared Moisture Meter from Azalab is a high-precision analytical instrument designed for fast, accurate moisture content determination across a wide range of materials. Utilizing advanced infrared (halogen) heating technology, the AZA0875 significantly reduces analysis time compared to conventional oven-drying methods, delivering reliable results within minutes.
This instrument is ideally suited for geotechnical laboratories, construction quality control, chemical and pharmaceutical industries, food processing, and material testing laboratories, where rapid and repeatable moisture data is essential for process control and compliance.
LIQUID LIMIT DEVICE WITH COUNTER AZA0853
The AZA0853 Liquid Limit Device with Counter from AZALAB is a precision-engineered instrument used for determining the liquid limit of soils in accordance with the Casagrande method. This test is a fundamental component of soil classification and geotechnical investigation, providing critical insight into the plasticity, compressibility, and shear strength of fine-grained soils.
Designed for reliable, repeatable, and standardized testing, the AZA0853 is widely used in geotechnical laboratories, civil engineering departments, construction quality control labs, and academic institutions.
Principle of Liquid Limit Test (Casagrande Method)
The liquid limit is defined as the water content at which soil transitions from a plastic state to a liquid state. In practice, it is determined as the moisture content at which a standard groove cut in the soil sample closes over a length of 12.5 mm under 25 blows of the liquid limit apparatus.
The AZA0853 consists of a polished brass cup mounted on an adjustable bracket. The cup is repeatedly raised and dropped from a fixed height of 1 cm onto a hard rubber base by means of a manually operated cam mechanism. A built-in mechanical counter accurately records the number of blows, ensuring compliance with testing standards and reducing operator error.
RAPID MOISTURE METER AZA0874
The AZA0874 Rapid Moisture Meter from Azalab is a compact, reliable, and field-proven instrument designed for quick determination of moisture content in soils, aggregates, sand, and other granular or fine materials. It is especially suited for on-site quality control in civil engineering, road construction, earthwork compaction, and geotechnical investigations, where timely moisture data is critical for effective decision-making.
Based on the well-established calcium carbide gas pressure method, the AZA0874 delivers accurate results within minutes, eliminating delays associated with laboratory oven-drying methods. Its portable, self-contained design makes it ideal for use at remote and demanding job sites.
SOIL CONE PENETROMETER AZA0851
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
