PowderPro
A1

Automatically measured parameters: angle of repose, angle of fall, spatula angle, bulk density, tapped density, dispersibility, voidage, and cohesion. Automatically calculated parameters: angle of difference, compressibility (Carr index), uniformity, flowability index, floodability index (Hausner ratio), and sieve size. All 11 parameters are obtained in a single measurement run.

In manual measurement, the operator estimates the powder cone angle visually or with a protractor — a method that introduces high operator-dependent variability. The PowderPro A1's CCD camera instantly captures the powder surface and the image recognition algorithm calculates the angle automatically. The result is operator-independent, reproducible, and fully documentable measurement data.

The variable-frequency rotary vibration system is adjustable from 50 to 300 taps per minute. Combined with selectable 3 mm or 14 mm amplitude, the cylinder rotation motion creates a horizontal, homogeneous powder surface before each measurement. This approach produces more repeatable tapped density results compared to conventional vertical-drop tapping mechanisms.

Yes. A separate SOP profile can be defined for each product or material, specifying the test sequence, vibration parameters, and acceptance criteria. The operator simply loads the sample, starts the system, and retrieves the result. Cross-contamination and operator-induced variation between products are prevented in GMP environments.

The PowderPro A1 is fully compliant with ISO 3953:1993 (tapped density), USP 32-NF27, and Ph. Eur. 7.0 (07/2010:20934E). These standards define international measurement references for tapped density, bulk density, and powder flowability parameters used in pharmaceutical quality control and industrial process development.
