Powder flowability tester PF1

flow rateflowabilityflow

Overview
The PF1 powder flow tester is designed for standardized testing in full compliance with Pharmacopeia requirements (USP <1174> and Ph. Eur. 2.9.36). The unit combines three standardized testing methods in one versatile instrument, enabling repeatable test conditions and quick change-over using tool-free quick-change components.

Key product information
The PF1 characterizes flow properties of powders and granulates using three standardized tests: Angle of Repose, Flow through an Orifice with a funnel, and Flow through an Orifice with a cylinder. Measurements can be reported as Volume per time or Mass per time (with an analytical balance). The design allows use of a stirrer or a filling funnel without removing components and features an integrated timer that starts/stops automatically with the shutter.

Setups / Modules

• Angle of Repose setup: standardized platform to measure cone height and calculate the angle of repose for powder classification.
• Flow through an orifice with funnel setup: truncated-cone funnel supplied with three interchangeable nozzles to standardize the opening; simulates powder flow along container/hopper walls.
• Flow through an orifice with cylinder setup: for “powder over powder” measurements; uses serial-numbered discs with different orifice diameters to vary the opening per Pharmacopeia guidance (up to 20 discs).

Benefits

• Three standardized flowability methods in one instrument for comprehensive characterization.
• Tool-free quick-change components to switch between funnel, cylinder and angle of repose tests.
• Stable stand with two height-adjustable arms and quick-locks for positioning.
• Compatible with stirrer or filling funnel without disassembly.
• Integrated automatic timer linked to shutter operation for consistent timing.
• Mass-per-time workflow with laboratory/analytical balances supported.
• Designed for fast, straightforward cleaning and repeatable test conditions.

Highlights

• Angle of Repose: standardized cone-height measurement to compute repose angle (classification examples: Carr ranges).
• Cylinder setup: avoids container-material effects; up to 20 serial-numbered discs with varying orifice diameters allow adjustment per pharmacopeial guidance.
• Funnel setup: truncated-cone funnel with three nozzles standardizes the flow-through opening; supports volume/time or mass/time recording.
