Definitions

  • the liquid containing the reactive constituent is introduced into a recess as a volume which is at most equal to the volume or less than the volume of the recess between its terminal cross-sectional openings.
  • a volume of the liquid smaller than the volume of the recess means that the liquid is arranged in the area of the smallest cross section of the recess and correspondingly there binds the reactive component to the inner wall, optionally to part of the surface of the first glass plate adjoining the smallest cross section .
  • the volume of the liquid can be, for example, 20 to 80% or 30 to 60% of the volume of the recess.
  • FIG. 1 shows the production of a carrier according to the invention from a first glass plate with a recess produced therein
  • FIG. 4 shows a section of a simple embodiment of the carrier made from a first glass plate 1, in which a conical recess 2 extending completely through the thickness of the first glass plate 1 is produced as a representative.
  • the glass plate 1 which is attached to the Places at which a recess 2 is to be created, through which a laser pulse radiates, the surface of the first glass plate 1, in which the smaller terminal cross section 3b of the recess 2 is to be arranged, is coated with etching resist before etching.
  • a drop of liquid 10 which is brought to or into the recess 2, is also arranged in the embodiment of the continuous conical recesses 2 in the area of the smaller terminal cross-sectional opening.
  • one or both of the opposing surfaces of the first glass plate 1 can have a hydrophobic coating 4.
  • a channel 19 is formed in a surface of the first glass plate 1, for example introduced by etching.
  • the channel 19 opens into the recess 2 so that liquid can pass from the channel 19 into the recess 2. If the first glass plate 1 or the channel 19 is arranged such that the channel 19 is arranged in the lower surface of the glass plate 1, a channel 19 arranged there is suitable for discharging liquid from the recess 2.
