System for collecting liquids from outlet tube of e.g. molecules separation/purification instrument in liquid chromatography to search new drugs in e.g. cosmetic industry, has plate positioned on tubes and pierced with conical holes

摘要

The system has a plate (11) positioned on tubes (9) and pierced with a series of conical holes (12), where the holes have similar geometry. The holes are concentric with each tube and prevent loss of liquid when a washing bottle is moved from one of the tubes to another tube. Diameter of the holes is larger than the distance between centers of the holes such that the holes form a hyperbolic sharp edge (13) in order to distribute a jet of fluid gradually without splash when the fluid is moved from the former tube to the latter tube.
