FIELD: chemistry.SUBSTANCE: group of inventions relates to making preparations of adhering or non-adhering cells and/or particles, contained in liquid. Compartment (10) for making said preparations contains accumulation chamber (20) for storing liquid in accumulation chamber in suspended state against force of gravity, acting on liquid, only due to forces of adhesion and/or superficial tension. Accumulation chamber is made with possibility of storing liquid, which contains cells and/or particles, and discharge of stored liquid, containing said cells and/or particles, through output opening (22) by application of specified external force, in particular centrifugal force. Compartment contains channel (30), located adjacently to output opening (22) of accumulation chamber (20), with output opening (22) of accumulation chamber (20) leading to said channel. Channel (30) has section, larger than section of output opening (22), and wall in the place of transition from output opening (22) into channel (30) forms edge (32). Compartment also includes subject section (50) for reception of output liquid, containing said cells and/or particles, and absorbing means (40), located adjacently to subject section (50) between channel (30) and subject section (50). Absorbing means (40) has opening (42) , making it possible for liquid, containing said cells and/or particles, move through opening (42) onto subject section (50), and additionally removes liquid from liquid, containing said cells and/or particles, on subject section (50) in such a way as to leave said cells and/or particles on subject section (50) for analysis.EFFECT: realisation of more efficient, reliable and high-quality making of preparations of cells and/or particles, contained in liquid.25 cl, 14 dwg |
