Powder fluidity test

1. evaluation of powder material fluidity

As a simple device, raw materials from different suppliers or batches may vary greatly. This change will affect the ability of the powder to flow freely in the process of entering the production line, thus damaging the efficiency and quality of the manufacturing process. The fluidity index of drug powder measured is in the range of 4-40.

This index can be used as a parameter of raw materials. Many factors affect the fluidity of powder, such as:

Particle size and shape, fineness, unit surface area, actual density,

Bulk density, porosity, sedimentation characteristics, electrostatic charge

The inherent fluidity test method is based on the ability that the powder can freely pass through the small hole on the disc. This device has a group of 19 discs, and the hole diameter ranges from 4mm to 34mm. When used in pharmaceutical production, the device fully meets the requirements of usp1174 powder fluidity test.

2. inherent liquidity

3. basic technical features and parameters

1) Disc aperture (mm) 4, 5, 6, 7, 8, 9, 10,12, 14, 16, 18, 20, 22, 24, 26, 28,30, 32, 34

2) Compliance with USP 1174 liquidity test

3) Consistency and repeatability of liquidity indicators

4) Quick flow test before powder production filling

5) Including a full set of discs suitable for various powder materials

6) Stainless steel funnel to eliminate the formation of static electricity between particles

7) Is a quality assurance specification for procurement and receipt

8) Coefficient of variation to help avoid product consistency

9) It is suitable for all kinds of materials used in production, such as preparation factory, coffee, sugar, plastic, powder coating, etc.
