Bulk Density Measurement Tester
The Bulk Density Measurement Tester is a precision instrument designed to determine the bulk density of powders, granules, and particulate solids. Bulk density is a critical property affecting flowability, packing, and processing performance in industries such as pharmaceuticals, chemicals, food, and materials science. The tester provides an objective, quantitative method for evaluating the mass per unit volume of particulate materials under controlled conditions.
Application
(1) Determining bulk density of pharmaceutical powders, granules, and excipients.
(2) Evaluating flow and packing characteristics of food powders, sugar, salt, and grains.
(3) Quality control of chemical powders, catalysts, and pigments.
(4) Process optimization for material handling, storage, and transport.
(5) Research and development of new powder formulations with improved flow properties.
(6) Determination of loose/poured density and comparison with tapped density for compaction studies.
Standards
(1) ASTM B212 — Standard Test Method for Apparent Density of Powders
(2) ASTM D1895 — Standard Test Methods for Bulk Density and Tapped Density of Powders
(3) ISO 60 — Determination of apparent density of powders
(4) ISO 697 — Methods for determining density of granular materials
(5) ISO 787-11 — Test methods for chemical analysis of ceramics; apparent density measurement
(6) USP <616> — Bulk density determination for pharmaceutical powders
