FIELD: process engineering. ^ SUBSTANCE: invention is intended for analytical membrane filtration of fluid. Device comprises analytical membrane filter, support screen arranged in the base communicated via pipeline with evacuated filtrate collector, bottle with fluid to be filtered feeding fluid, when turned upside down, into filter, tune-holder wherein said bottle is inserted. Said bottle has its ID exceeding bottle neck OD and is jointed to the base from above. Said holder has bottle neck support representing a circular ledge with ID smaller than bottle neck OD. Pipeline is provided with valve and is connected to filtrate collector by quick-release joint. ^ EFFECT: possibility to replace membrane filter in sample filtration without completing filtration. ^ 7 cl, 6 dwg, 2 tbl |
