PF 1 Powder Flow Tester


Standardized powder flow characterization, USP <1174> and EP 2.9.36 , Flow through an Orifice and Angle of Repose.

 

Powder and Granulate Flow Tester

The PF 1 powder flow tester has been specifically designed for standardized testing in full compliance with Pharmacopeia requirements as laid down in USP <1174> and EP 2.9.36. Its optimized design allows for different, yet easily repeatable test conditions and methods for powder flow characterization. Change-over between configurations is simple with quickchange components that do not require any additional Tools.

  • Adjustable height
  • Easy-to-clean
  • Integrated timer
  • Quick-Change components

 

Flexible Configurations

The PF 1 can be configured to perform different types of powder flow tests – and allows to vary test conditions for each test type in a repeatable way. When equipped with an analytical balance, the flow rate can be measured continuously to detect momentary flow rate variations.

  • “Flow through an Orifice” with Cylinder or Funnel
  • “Mass per Time” or “Volume per Time”
  • Angle of Repose

 

Flow through an Orifice

Using the Cylinder setup is ideal to determine the flow rate of “powder moving over powder”. This method eliminates the effect of the container material on test results. Discs with different orifices allow for variation of the flow-through opening diameter as described in USP.

 

To simulate the flow of powder moving along the wall of a container or hopper in a production situation, a Funnel in the form of a truncated cone (with 3 different nozzles) is also readily available for the PF 1.

 

Angle of Repose

The “Angle of Repose” test allows evaluation of the flow properties of solids based on the shape of the cone. By measuring the cone height on a standardized platform, the angle of repose (in degrees) can be easily calculated to classify the powder (e.g. based on the range classifi-cation according to Carr).

 

To form a symmetrical cone on the platform, the height of the orifice through which the powder passes can be fixed – or varied as the pile forms.
