Angle of Respose

Powder properties is easily measured with an Angle of Respose instrument. The conical pile’s angle, relative to the horizontal base produced when a granular material is poured on to a horizontal surface, is related to density, surface area and coefficient of friction of the material.

This characterization system can be used according to pharmacopoeial methods USP1174 and EP 2.9.16. AB FIA – Prototypverkstaden has constructed this instrument where the dropping height of the powder can be varied.
