Description

Cell filter for sample preparation of flow cytometer

Technical Field

The utility model relates to a cell filter's technical field especially relates to a cell filter is used in preparation of flow cytometer sample.

Background

Flow cytometers are devices for the automated analysis and sorting of cells, which are capable of rapidly measuring, storing, displaying a series of important biophysical, biochemical characteristic parameters of dispersed cells suspended in a liquid, and of sorting specified cell subsets therefrom according to preselected parameter ranges. When a multicellular organism is analyzed by a flow cytometer by separating cells, cell nuclei or other organelles, a sample is filtered to remove large particles of impurities. At present, the cell sap filtration mode has two kinds, one kind is centrifugal, one kind is the gravity filtration formula, wherein the relative structure of gravity filtration formula is comparatively simple, only need a bobbin add the filter screen of a specific specification in the bottom can, but the filter effect is relatively poor, general improved generation is not only setting up the filter screen in the bottom of bobbin, but also set up the filter screen at the lateral wall of bobbin, through swaing the bobbin filter screen increase filtration area on the accessible lateral wall, but because the bobbin sways in the container, in order to avoid the bobbin to collide the container and cause the damage, it is less and hardly reach complete circumference and sway to wave amplitude, it is not enough to the filter screen utilization ratio on the bobbin.

SUMMERY OF THE UTILITY MODEL

the utility model provides a cell filter for flow cytometer sample preparation, including filter screen and cylindricality frame, be equipped with the filter screen on the cylindricality frame, the upper end nestification of cylindricality frame has the joint, the upper end of joint is equipped with the draft tube, it has the inner race to articulate on the left and right sides of joint is kept away from to the draft tube, it has the outer lasso to articulate on the lateral wall around the inner race, presses the outer lasso on the container through pressing, waves the upper portion of draft tube, the universal swing of the relative container of draft tube, the cylindricality frame is along with the universal swing of draft tube in the container for cell liquid in the cylindricality frame can filter through the filter screen on cylindricality frame bottom and the circumference lateral wall.

Furthermore, an inner hinge block is arranged between the guide cylinder and the inner ring, so that the guide cylinder can swing back and forth relative to the inner ring.

Furthermore, an outer hinge block is arranged between the inner ring and the outer ring, so that the inner ring can swing left and right relative to the outer ring.

Further, the joint head comprises a transition ring and a joint ring, the transition ring is arranged at the lower end of the guide cylinder, the joint ring is arranged at the lower end of the guide cylinder, and the joint ring is nested and in threaded connection with the upper end of the cylindrical frame.

Furthermore, a plurality of manual ribs are uniformly distributed on the part, close to the outer wall of the joint ring, of the upper end of the cylindrical frame along the circumferential direction, and the cylindrical frame is detached from the joint ring by rotating the part, corresponding to the manual ribs, of the cylindrical frame.

Further, an outer supporting ring is arranged on the peripheral side wall of the outer supporting ring, so that the outer supporting ring is pressed against the container opening, and the outer supporting ring and the container are relatively fixed on the horizontal plane.

The utility model discloses owing to adopted above-mentioned technique, make it compare specific positive beneficial effect with prior art and be:

the utility model discloses a set up an universal structure of waveing between cylindricality filter vat top and container for the cylindricality filter vat can be the universal swing of container relatively, improves the filter effect of cylindricality filter vat lateral wall.
