Abstract

A syringe adapter is used for connecting a dosing syringe to a container in order to take up a fluid. The syringe adapter has a fluid delivery channel for creating a flow connection between the inside of the container and the inside of the dosing syringe. At least one ventilation channel of the syringe adapter is used for creating an air connection between the inside of the container and the container surroundings. In at least one of the channels a non-return valve is arranged, which allows the passage of media in an open position and in a closed position closes the channel. This results in a syringe adapter which has improved handing and in particular provides sufficient dosing precision.
