Don’t confuse this with a Tap Density Tester . The Scott Volumeter measures aerated bulk density, while a tap tester measures packed density. You need both for a complete powder characterization profile.
Bulk Density Tester - Scott Volumeter - Ph. Eur. 2.9.34 - Antech
The is a specialized laboratory instrument used to determine the bulk density (also known as apparent density) of fine powders and granular materials . Unlike standard flow meters, the Scott Volumeter is specifically designed for materials that do not flow freely through a standard orifice. It is a cornerstone in industries ranging from pharmaceuticals to metallurgy, providing essential data on how powders will behave during manufacturing, packaging, and storage.

thermal side is facing up when loading into the paper cabinet. LABULK 2. Regulatory Standards (Scientific "Papers") If you are looking for the technical papers or standards that govern the use and construction of a Scott Volumeter, the tester is designed according to these international protocols: ISO 3932/2: International standard for Metal Powder Bulk Testing using the Scott Volumeter. ASTM B329: Standard Test Method for Apparent Density of Metal Powders and Compounds using the Scott Volumeter. USP <616>: United States Pharmacopeia method for Bulk Density and Tapped Density of Powders. Ph. Eur. 2.9.34: European Pharmacopoeia chapter on bulk density. GB/T 5060-85: Chinese national standard for Metal Powder Density Testing. Guangdong Hongtuo Instrument Technology Co., Ltd. +2 3. Sourcing the Equipment If you are looking to purchase the tester itself or its specific accessories, common manufacturers and retailers include: Copley Scientific (UK): Offers models compliant with Ph. Eur. 2.9.1 and Don’t confuse this with a Tap Density Tester
Unlike a simple cup and funnel (ASTM B212) used for free-flowing powders, the Scott Volumeter is designed for materials that bridge or clump. It uses a series of angled glass baffles (a "trip plate" or "zigzag" chute) to break up agglomerates and standardize the falling action of the powder into a calibrated cup.
The primary value of the Scott Volumeter lies in its ability to provide a of "Apparent Density." Bulk Density Tester - Scott Volumeter - Ph
For laboratories implementing this device, it is recommended to perform a Gauge R&R (Repeatability and Reproducibility) study to ensure operators are leveling the density cup consistently.
It is crucial to understand when to use the Scott Volumeter versus the Hall Funnel.
A standard Scott Volumeter setup includes:
