Flowability tester PF1

flowflow ratepowder flowability

Overview
The PF1 powder and granulate flow tester PF1 is designed for standardized characterization of powder flowability in full compliance with pharmacopeial methods (USP <1174> and Ph. Eur. 2.9.36). The instrument integrates three test types in one compact, tool-free system to ensure repeatable conditions and fast changeovers.

Key features

• Three standardized tests: Angle of Repose; Flow through an orifice (funnel); Flow through an orifice (cylinder).
• Configurable orifice tests for funnel or cylinder setups to simulate wall-driven flow or powder-over-powder flow.
• Cylinder mode uses 20 serial-numbered discs with varied orifice diameters per pharmacopeia protocols.
• Funnel mode includes a truncated-cone funnel with three interchangeable nozzles for reproducible outlet geometries.
• Robust stand with two height-adjustable arms and quick-lock mechanism for tool-free adjustments.
• Flexible configuration: use a stirrer or filling funnel without disassembling other parts.
• Integrated timer auto-starts/stops with shutter operation; results recorded as volume/time or mass/time (mass via analytical balance).
• Design optimised for rapid, trouble-free cleaning.

Applications
The PF1 is intended for pharmaceutical R&D, quality control and laboratories requiring harmonized pharmacopeia-compliant powder flow characterization and method development.

Highlights (method summaries)

• Angle of Repose: Forms a cone on a standardized platform and measures cone geometry to calculate repose angle; orifice height can be fixed or varied during pile formation.
• Cylinder setup (flow over powder): Measures flow rate of powder over powder and minimizes container-material effects using serial-numbered discs with different diameters.
• Funnel setup (flow along wall): Simulates flow along container or hopper walls using standardized nozzles; outputs can be recorded as volume/time or mass/time.
