Now, if the substances are moved exactly to the outer edge of the spacer, where the covering is as a stop, they are all aligned exactly in the same plane relative to the surface of the sample carrier. For example, with a horizontally oriented sample carrier, they are located at exactly the same height above it.
  • a locking means is arranged on the side facing away from the sample carrier of the cover.

  • sample carrier according to the invention applies equally to the method according to the invention and vice versa.
  • the method according to the invention can be carried out in particular with the sample carrier according to the invention.
  • the recesses are covered with a covering.
