Description

AZA 0892: Universal Extractor Frame (Screw Type) for Seamless Soil Sample Extraction

The AZA 0892 Extractor Frame Universal (Screw Type) from Azalab is an indispensable tool for any geotechnical lab or civil engineering testing facility requiring efficient and careful soil sample extraction. Designed with a universal approach, this robust apparatus is capable of extracting compacted or undisturbed soil samples from a wide array of molds and compaction cones, including standard Proctor molds, Modified Proctor molds, CBR molds, and various field density compaction cylinders. The reliable screw type mechanism ensures a smooth, controlled, and steady application of force, which is paramount in preserving the integrity of the extracted soil specimen, minimizing disturbance, and maintaining its in-situ properties for accurate laboratory analysis.

The process of extracting soil samples from molds without causing undue disturbance is critical for obtaining reliable test results. For instance, in compaction tests like Proctor or Modified Proctor, the extracted sample is often used for density determination or further strength testing. Similarly, in CBR (California Bearing Ratio) tests, the integrity of the compacted sample directly influences the accuracy of the bearing capacity assessment. The AZA 0892 Extractor Frame addresses this crucial need by providing a stable platform and a powerful yet controllable extraction force. The manual screw type operation allows the user to apply pressure incrementally, ensuring that the sample is gently pushed out of the mold, preventing cracking, crumbling, or altering its compaction characteristics.

The universal nature of the AZA 0892 is a significant advantage, as it reduces the need for multiple, specialized extraction frames. Its adjustable features allow it to accommodate different mold diameters and heights, making it a versatile addition to any geotechnical lab. The frame typically consists of a sturdy steel base, a vertical loading screw with a hand wheel, and a top platen or adapter that presses down on the sample. The mold containing the sample is placed on a support within the frame, and as the screw is turned, the sample is steadily pushed out. This design streamlines the sample preparation workflow, saving time and effort, especially when dealing with a high volume of samples.

Azalab’s commitment to providing high-quality geotechnical lab equipment is evident in the durable construction of the AZA 0892 Extractor Frame. Manufactured from heavy-duty steel, it is built to withstand the rigors of continuous laboratory use, ensuring long-term reliability and consistent performance. This extractor frame is an essential complement to compaction equipment and can be used in conjunction with various standards for soil testing, such as those published by ASTM International (e.g., related to soil compaction or CBR testing) and IS standards. Understanding the importance of proper soil sample extraction techniques is fundamental to accurate soil mechanics analysis. For further reading, resources on “soil compaction theory” or “CBR test procedures” can provide additional context on why undisturbed sample extraction is vital.

By integrating the AZA 0892 Extractor Frame Universal (Screw Type) into your operations, you ensure that your soil sample extraction process is efficient, reliable, and respectful of sample integrity, ultimately leading to more accurate and dependable geotechnical testing results.
