Sieve insert p-15  1mm trapez perf., chromium-free steel

Sieve inserts determine the final fineness of a sample.

Sieve inserts with trapezoidal perforation and square perforations are offered. Sieve inserts with trapezoidal perforations improve size reduction through extra shearing action. Sieve inserts with square perforation are recommended for the grinding of brittle materials and materials of medium fineness with a narrow grain band.

For the sample preparation according to RoHS and WEEE (for the poof of hexavalent chromium) and for the XRF analysis we especially recommend chromium free steel ST12 sieve inserts.
For all other applications sieve inserts made of stainless steel may be used, since these are harder and therefore more resilient against abrasion.
