Sieve Shaker

Hi all,

An issue regarding in-process tets equipment (sieve shaker), is it enough to calibrate the seives or a validation activity is requested ?

Thanks for your advise.

Sieving is a unit process in Oral solid dose manufacturing and it is first unit operation.
One must validate and calibrate the sieves.
There are techniques to check the mesh size (Integrity) also.
Its very important qualification and Validation process.
