Functional principle of the baskets
The baskets of Sieva-3 are available in two versions. As a perforated and a non-perforated basket.
The perforated basket 221.07 V02 is used for the filtration method. Therefore, a filter with desired
pore size is placed into the inner wall of the basket. Due to the centrifugal force, small particles of
the solution remain suspended in the filter and the filtered liquid is pressed through the holes of the
basket (see Figure 4).
Figure 4: Filtration method
The non-perforated basket 221.07 V04 is used for decantation method. After adding of the solution,
the sediment is pressed against the inner wall of the basket and stands upright due to the centrifugal
force. The light liquid is discharged via the opening in the lid of the basket (see Figure 5).
