Angle of Repose
Providing a simple method for assessing the frictional characteristics of powders, the Copley Angle of Repose module is ideal for predicting manufacturing issues associated with gravitational flow.
Comprising a 100 mm diameter circular test platform together with a digital height gauge, powder heights of up to 145 mm can be easily read from the clear display.
The tangent of the Angle of Repose (θ) is determined by measuring the height of the powder cone in mm and dividing it by 50. The inverse tangent of this figure provides the Angle of Repose in degrees.

Flow-Through an Orifice via Cylinder
Comprising a stainless-steel cylinder measuring 76 mm x 57 mm and a capacity of 200 mL, each module comes complete with 20 interchangeable stainless-steel disks with a precision orifice from 4 to 36 mm.
Flow Through an Orifice tests can be undertaken in several ways:
- Quantitative flowability test based on fixed mass or fixed time to understand the uniformity and consistency of power flow
- Intrinsic flow properties of a powder via a Flowability Index based on comparative assessments

Flow-Through an Orifice via Funnel
Designed in accordance with USP <1174> and Ph. Eur. Chapters 2.9.36 and 2.9.16 for Flowability, the stainless-steel funnel and nozzles simulate flow in a hopper or other similar production equipment.
Supplied with 5, 7, 10, 15 and 25 mm aperture quick-change nozzles, the funnel is manufactured from pharmaceutical grade 316 stainless steel. Testing is performed using a simple, user-friendly shutter system.
Optional Balance and Timer attachments further simplify mass vs time tests.

Bulk Density via Scott Volumeter
The Scott Volumeter is described in both USP and Ph. Eur. and is suitable for evaluating the bulk density of a diverse range of powders and granules.
A comparison of the bulk and tapped density of a powder provides valuable insight into behaviour during handling and storage and can be used to determine well-established metrics of Carr’s Index and Hausner Ratio.
