FIELD: drawing liquid samples for fast and simple qualitative and quantitative analytic analysis of liquid sample components.
SUBSTANCE: proposed device 1 is used for carrying the sample over capillary active passage 2 from point 3 of sampling to point 4 of receiving the sample; capillary active passage 2 is formed by backing 5, coat 6 and intermediate layer 7 located between backing and coat; intermediate layer 7 defines geometry of capillary active passage; backing 5 at sampling point 3 projects beyond coat 6 and intermediate layer 7 is shifted backward at this point in way of receiving point 4 and consequently backing 5 and coat 6 project beyond intermediate layer 7.
EFFECT: ease of drawing samples by means of auxiliary facilities and proportioning of liquid.
