Accurate particle size analysis with Veco's test sieves
Test sieves are precision metal sieves applied for particle size analysis for a large variety of products, both in laboratories for production control and in production process itself. Sterile filtration, absolute filtration, critical cell-cell separation, cell deformability testing, cell harvesting, particle sieving (diamonds, seeds, and dust), cacao filtration, flow regulation and laboratory testing are all typical fields where the micro sieves are utilized.
The test sieves come in a patented steel frame and are produced in compliance with ISO 3310. Standard frames sizes are 60 mm, 75 mm, 100 mm, 125 mm, 200 mm, 3 inch and 8 inch. A test report is delivered with every sieve.
Besides the ISO-range, we also manufacture custom design sieves based on customer’s specific demand.
Material: Electroformed Nickel (medium or hard up to 600 Vickers)
1” and 2” high frames
Tolerances +/- 2 micron for hole sizes up to 500 micron
Tolerances /- 4 micron for hole sizes from 500 micron and up
