The LABULK 0335 Tap Density Tester is a device specifically engineered to assess the tapped density of powders through the volume method. In contrast to the AIMSIZER Comprehensive Powder Characterization Tester, which is capable of measuring 15 physical parameters, this instrument is limited to measuring only the tapped density of a powder. This measurement can subsequently be transformed into the compressibility index and Hausner ratio, which are essential for characterizing the tapped density of the powder.
The device comprises a vibration platform, a vibration assembly, a graduated cylinder, a touchscreen control system, and a printer. Its features extend beyond the standard functions and configurations found in conventional tapped density testers, incorporating the following software capabilities: a two-tier management system with both administrator and operator accounts, accessible through password protection; an adjustable rotation speed ranging from 0 to 300 rpm, complete with a digital real-time display; preset vibration counts for 10 common Standard Operating Procedures (SOPs); automatic computation of the Hausner ratio and compressibility index; and the functionality to store and retrieve test results.
These attributes render it a thorough solution for characterizing the flow properties of powders. Additional specifications include a 7-inch color touchscreen that aligns with contemporary trends, providing a user-friendly, technology-driven experience; a precision stepper motor regulated by the operating system, guaranteeing zero error in rotational counts for enhanced accuracy of results; and adherence to Pharmacopoeias by integrating the compressibility index and Hausner ratio for more comprehensive testing.
A versatile power supply operating at 110 V/220 V, designed for global applicability; real-time data storage that allows for straightforward retrieval; test outcomes displayed flawlessly through the integrated printer, with an optional dot matrix printer available for permanent documentation; rigorous compliance with Pharmacopoeia-level tolerances concerning the weights of the graduated cylinder and vibration assembly; adjustable rotation frequency (rpm) tailored to fulfill R&D requirements; automatic self-diagnostic feature upon startup to promptly identify any issues; and optional unlimited data storage and export capabilities. This device adheres to various international standards, including ISO, ASTM, USP (United States Pharmacopeia), and EP (European Pharmacopoeia).

Pour the loosely packed powder into a graduated cylinder to measure the sample's volume and weight. Secure the graduated cylinder to the vibration assembly. Position it on the vibration platform, which features a lower section with cams. The touchscreen control system activates the base of the vibration assembly at a predetermined frequency and amplitude, causing the graduated cylinder to move vertically.
The powder's volume within the cylinder decreases to varying degrees depending on its properties. By dividing the sample mass by its tapped volume, one can determine the sample's tapped density. Hausner ratio and compressibility index can be computed in accordance with standard specifications. Along with tapped density, these parameters provide a comprehensive characterization of the powder's flowability.
