The utility model discloses a kind of
exosome concentration preparation devices, comprising: cover,
exosome tank, connector, concentration tank and
regulator, the cover,
exosome tank, connector, concentration tank and
regulator are sequentially arranged from top to bottom, the upper and lower ends of the exosome tank and concentration tank are respectively provided with first thread groove and second thread groove, the inside middle part and inside lower of the connector are respectively provided with annular clamping groove and step, the top of the step is equipped with
dialysis membrane, and the top of the
dialysis membrane is equipped with grid support. The utility model can adjust the addition amount of concentrated agent by adjusting the height position of
piston, ensure that concentrated agent and
dialysis membrane are in
close contact, can also extrude water-absorbing
sponge type concentrated agent to
discharge moisture, restore its water absorption performance, improve the rate of reuse, and the device is connected by thread, and the components are assembled and disassembled conveniently, suitable for laboratory
rapid processing large volume sample, without relying on complex equipment such as ultracentrifugation.
