PORT FOR FEEDING TEST CHEMICAL COMPOUND AND WITHDRAWAL OF FLUID FROM CELLS FOR CULTIVATION OF CELL MODELS Russian patent published in 2016 - IPC C12M1/26 G01N1/10 C12Q3/00 

FIELD: biochemistry.

SUBSTANCE: invention relates to structural elements of micro bioreactors. Disclosed is port for administration of tested chemical compound and withdrawal of fluid from cell for cultivation of cell models. Port is made of fixed and moving parts. Each part is equipped with two through holes, and fixed part is additionally equipped with extended slot on side of end surface. Fixed part has top and bottom parts. Lower part is made with possibility of its tight placement in cell, and upper part is made with recess for placement and fixation of movable part to turn latter relative to axis of valve in "open" and "closed" positions. In open position through holes in fixed and moving parts are combined to form two channels for insertion and withdrawal, and in closed position through holes of movable part are combined with extended slot to form channel for flushing of through holes.

EFFECT: invention provides sterility in multiple input and fluid sampling and minimising mechanical effects on cells.
