Abstract

The device for measuring the sampling calibration particles comprises an optical system, eg a microscope (1) for determining the size of calibration particles with a slide (7) for placing the particles. The slide is made of transparent material and arranged normal to the optical axis. A micromanipulator (12) is also provided, fashioned as a needle with the diameter of its end interacting with the sampled particles selected from the relationship where d0 is the needle end diameter and d1 is the particle diameter. The material of the needle is selected so that the adhesive forces between the needle and particle exceed the adhesive forces between the particle and slide.
