Detailed Description
The invention is described in further detail below with reference to the drawings in the specification:
example (b):
a device for washing cells comprises a body 1, wherein a rotor 2 is arranged at the bottom end in the body 1, and an upper cover 3 is hinged to one end of the body 1; the upper end of the rotor 2 is coaxially connected with a test tube disk 4, the section of the test tube disk 4 is circular, and a plurality of test tube positions 5 for placing test tubes are arranged in an array along the circumferential direction of the test tube disk; the test tube position 5 is used for inserting test tubes containing cells to be tested.
The bottom of test tube is equipped with the bump, and 5 bottoms in test tube position are equipped with the concave point, and when the test tube was put into the test tube position, bump and concave point adaptation prevented the in-process slippage of test tube at equipment start.
Towards the one side of body 1 when upper cover 3 closes and be equipped with washing dish 6, washing dish 6 is the star configuration, and it connects each contact 8 through central point 7, is the transmission dress, and central point 7 passes through expanding spring to be connected in the intermediate position of upper cover 3, and when equipment closed, expanding spring was compressed, leads to the washing dish to compress tightly the test tube dish under it to compress tightly wherein test tube, further prevent the test tube at the in-process slippage of equipment start.
