Bulk Density Tester - Scott Volumeter

Simple and robust equipment which is used to test the characteristics of bulk density for powders according to the regulations of USP and EP.



Step 1: weight the empty receiving cup

Step 2: allow an excess of powder to flow through the apparatus into the sample receiving cup until it overflows.

Step 3: scrape carefully the excess powder from the top of the cup using a spatula.

Step 4: weigh the filled cup again and calculate the powder weight

Step 5: calculate the bulk density of the powder using the known volume as follows:


Density (g/ml)= Weight / Volume


Step 6: repeat the steps above for at least three different powder sample and take the average.
