in a blow-fill-seal process, involves simultaneous filling of 5-units (a single cassette packed as unit) ;
an inprocess controls and monitoring involves weight and volume checks wrt target.
for the final qc-testing, samples are selected for analysis; and
the question is, if we have to pickup 10 samples for a given test, should we pick up 2-casettes; or shall we pick up randomly 10-individual units randomly from the batch.
i would like to propose that, 10 samples for each of the simultaneous filling nozzles shall be randomly selected; (considered that the 10 samples are statistically justified and adequate)
