english: This is not scalable, and also when you do things by hand, even in the best laboratories, you have variations in techniques, and you need to know, if you're making a drug, that the Aspirin you're going to take out of the bottle on Monday is the same as the Aspirin that's going to come out of the bottle on Wednesday.
non_english: Ta brzina produkcije se ne može povećavati, a isto tako kada radite ručno stvari čak i u najboljim laboratorijama, dolazi do varijacija u tehnikama, a neophodno je da znate, ukoliko proizvodite lek, da je aspirin koji ste uzeli iz boce u ponedeljak, isti kao i aspirin koji će se naći u toj boci u sredu.
