摘要

The plate has a set of fluid passages and/or fluid channels provided with a residue-resistance coating on two sides, where the coating exhibits PTFE. A set of concentrically arranged slot patterns or a set of linearly arranged slot patterns and a hole pattern are arranged in the plate. A fixation unit controls a rotation to a base with the corresponding fluid channels, where the plate consists of a metal such as ferrous alloys and/or steel, or adequate plastic such as polyimide with high firmness.
