Yes – use a 10 mL or 25 mL cylinder with 0.001 g balance. Some micro-tap density testers exist (e.g., Quantachrome Autotap with 5 mL insert).
This document provides general guidance. Always refer to your specific instrument manual and required regulatory standard for exact test parameters. bulk density tester
Pycnometer measures true density (solid only, no voids). Bulk density tester includes voids. For the same powder, bulk density ≤ true density. Yes – use a 10 mL or 25 mL cylinder with 0
USP <616> specifies: 500 taps initially. If volume reduction >2% from 500 to 1250 taps, continue to 2000 taps. Most free-flowing powders stabilize by 500 taps. 2% from 500 to 1250 taps
