A device, process and system are provided for collecting and releasing a liquid sample, especially saliva. A defined saliva sample, i.e., a filtered, approximately homogeneously mixed saliva sample of a predetermined volume is made available in the simplest possible manner. A sampling tip () is provided made of a dimensionally stable and porous material, which is moved with its mouthpiece () in the mouth of a test subject for one to two minutes and takes up saliva based on the capillary action. A reagent liquid enters the pores of the sampling tip (), mixes with the saliva there and is subsequently fed from a reagent depot by the action of pressure. The saliva and the reagent liquid are finally discharged as a droplet () in the filtered and mixed state, either into the cavity () of the sample collector or into a filter mixer.
