PYCNOMETERS AZA0883
The AZA0883 Pycnometer Apparatus from Azalab is a precision laboratory instrument designed for determining the specific gravity (particle density) of soils and aggregates smaller than 10 mm, including clay, sand, and fine gravel. Manufactured in compliance with BS 812, this apparatus delivers accurate, repeatable, and standards-compliant results essential for civil engineering, geotechnical investigations, and construction material testing.
The pycnometer method is widely recognized for its simplicity, reliability, and suitability across a broad range of fine-grained materials used in concrete mix design, pavement construction, and soil characterization.
Description
Purpose & Principle of Test
The AZA0883 operates on the pycnometer method, where the mass of a known volume of soil particles is determined using water displacement. A precision-fitted brass cone and airtight rubber seal ensure that no air is trapped or lost during weighing, maintaining volume integrity and ensuring accurate calculation of specific gravity as per BS 812 procedures.
