Powder flow tester for pharmaceutical powder flowability
In pharmaceutical manufacturing, accurately characterizing the flow properties of powders and granulates is crucial for ensuring consistent quality and efficient processing. A reliable assessment of flowability can prevent production issues such as clogging, inaccurate dosing, and inconsistent blending.

Assess powder flowability using Usp-compliant methods
The PF1 powder flow tester by Sotax AG is designed to provide standardized testing in compliance with USP <1174> and Ph. Eur. 2.9.36 guidelines. This equipment combines three standardized methods to evaluate powder flowability: the angle of repose, flow through an orifice with a funnel, and flow through an orifice with a cylinder. Each setup can be switched quickly without the need for additional tools, simplifying the testing process. The robust stand includes height-adjustable arms that are easy to lock in place. Integrated timers facilitate automatic start and stop functions when opening or closing the shutter, ensuring accuracy in measurements. This tester is optimized for fast and efficient cleaning, making it suitable for both research and production environments.
