This is based on 10mm tooling at 300mg. If API is in short supply we can look at reducing the tooling size.
Make sure that the batch number and material name that you require on your report and results are written on your samples.

They are one of the most common problems in tablet manufacturing. It can be a costly problem to solve.
Sticking and Picking are 2 different problems that can occur during the manufacturing of tablets:
Sticking is when particles adhere to the faces of the punches instead of sticking together to form a tablet. Sticking can occur on any area of the tooling face and can occur at any time during the manufacturing.
Picking is when particles adhere to logos and letters used on some punches, this usually occurs within the “closed” numbers and letters, these numbers are 0,4,6,8, and 9, some of the letters are A, B, D, and e.
If you know the moisture content, particle size distribution or any other product properties, can help you to know whether a product will stick or not.
