FIELD: process engineering.SUBSTANCE: set of invention relates to entrapment of biological particles suspended in fluid for preparation of biological specimens for cytological analysis. It relates also to preparation of biological specimens with the help of this device, to platform and system for multianalysis. This device comprises pipe with first and second ends. Note here that pipe first end is closed by filter membrane surface glued to pipe wall cross-section. It includes the piston composed by rod engaged with thrust element. Note also that said rod can slide in axis parallel with pipe wall. Besides, it comprises the unit of hydrophilic absorbent arranged in said pipe between filter membrane inner surface and piston thrust element. Proposed process comprises placing aforesaid device in vessel with fluid wherein suspended are biological particles, retaining said device in said vessel for time sufficient for entrapment of a portion of biological particles on filter membrane surface. Then, this device is removed from said vessel to collect trapped biological particles from membrane filter.EFFECT: production of high-quality cytological preparations using simpler device.18 cl, 11 dwg |
