Definitions

  • the invention relates to a glass pipette with metering markings.
  • the metering mark is printed or incised.
  • Carved markings increase the pipette's susceptibility to breakage. With color printing there is a risk of contamination when the pipette is immersed in the liquid to be pipetted.
  • the invention seeks to remedy this.
  • the invention solves the problem by means of a metering pipette which is provided with pressed-in metering marks.
  • the glass bulb 1 with a bead 5 at one end and an inlet or outlet opening 6 at the other end is provided with pressed-in metering marking rings 2.
  • the bead 5 serves to receive the suction device 3 and the screw cap 4 for the container (not shown) with the filling material to be dosed.
