Finally, the contaminated water from the ultrasonic bath is removed from the sieve by rinsing with water and/or ethanol.	+	Sieving is complete if there is no or only little powder left on top of the sieve. Note that large agglomerates or particles will intentionally not pass the sieve and should be discarded.

-The amplitude is determined optically via the sieve cover. There are lines at various specified intervals on the sieve cover. The amplitude is increased or decreased via the keypad until the lines of the desired distance are optically one above the other. The optimum amplitude is reached when the sieve aids almost or only very lightly touch the sieve cover. This can easily be heard by clicking noises.

 The top sieve of the sieve tower is carefully filled with the material to be sieved and the sieve aids from a small height in order to avoid damage and dust. A spatula or spoon should not be brushed over the mesh in order not to damage it. If the amount of sieve aids exceeds 300 g, the material must be sieved in portions to avoid damaging the sieves. If the balls from the previous grinding process are not used, 10 mm grinding balls are recommended as additional sieving aids.

−	A sieve shaker is used to separate powder and grinding balls, crush agglomerates and fractionate a powder into different particle sizes. When equipping a vibrating sieve, a distinction is made between dry sieving and wet sieving. Only dry sieving with a Fritsch Analysette 3 Spartan is described here. Separate sieving equipment should be used for each material in order to avoid cross-contamination. Note that it is difficult to completely clean a technical sieve.	+	A sieve shaker is used to separate powder and grinding balls, crush agglomerates and fractionate a powder into different particle sizes.

Note that it is difficult to completely clean a technical sieve, so that siving inherently is prone to contamination.
