Retsch has developed an unique manufacturing process that guarantees a previously unattained quality and consistency in sieve production.r- One piece construction and fabrictransition without any grooves to prevent cross contamination (no solder, no residues etc.).r- A high degree of corrosion resistance and ease of cleaning due to high-alloy stainless Steel (specifications 316).r- 15 % lighter than traditional sieves while at the same time increasing the free sieve area.r- Maximum stability and optimum sealing when used in sieve stacks.r- Innovative resistance welding technology guarantees permanently tight sieve fabric.rEspecifications for 200x50mm test sieves are detailed below. Also, they are available test sieves of 203mm of diameter and 25mm of height.r
