Detailed Description

The utility model is described in further detail below in connection with specific examples:

As shown in fig. 1 to 4, a centrifugal tray for a cell slice preparing clamp comprises a tray body 1 which is arranged on a centrifugal tray 100 and can swing, and a balancing weight 2 is arranged at the bottom of the tray body 1. The cell slide clamp comprises a slide cabin 4, a slide glass 5 and a base 6. When the centrifugal tray 100 is placed in a static state, the centrifugal tray does not swing greatly due to the gravity action of the balancing weight 2, so that cell liquid in the tablet making bin 4 is prevented from overflowing due to shaking, the balancing weight 2 is subjected to the gravity and centrifugal force in the initial centrifugation process, so that the centrifugal tray on the centrifugal tray 100 keeps the same inclination direction, the samples in the tablet making bin 4 are prevented from splashing and cross-polluting each other, and the balancing weight 2 enables the tray body 1 to have a certain weight in the high-speed centrifugation process, and the samples are prevented from splashing.

The balancing weight 2 can be detached, so that the balancing weight 2 is convenient to detach, clean and sterilize, and is convenient to replace balancing weights 2 with different weights so as to adapt to different centrifugal speed requirements. The weight of the balancing weight 2 is 20-100g, preferably 20-50g, more preferably 25-40g. The weight of the disc 1 together with the weight 2 is preferably 50-110g. The balance stability in the liquid centrifugal motion in the tablet making bin 4 is ensured, the splashing is avoided, and the influence on the centrifugal speed of the centrifugal machine is minimized.

Preferably, the balancing weight 2 is arranged in the center of the disc body 1, so that the disc body 1 can be quickly kept balanced in centrifugal motion.

Further, the tray body 1 is provided with two base bins 11 for placing cell sheet-making clamps, a balancing weight connecting groove 12 is arranged between the two base bins 11, and the balancing weight 2 is connected to the balancing weight connecting groove 12. The balancing weight 2 can be clamped on the disc body 1, and preferably the balancing weight 2 is connected to the center of the disc body 1 through a screw 3. More preferably, the balancing weight 2 is in a weight shape, which is beneficial to keeping the centrifugal motion balance of the tray body 1.

In a specific embodiment of the utility model, two sides of the disc body 1 are respectively provided with a hanging lug groove 13 connected with the centrifugal disc 100, and an anti-falling rib 14 for preventing the disc body 1 from falling off the centrifugal disc 100 is designed in the hanging lug groove 13. The disc body 1 can swing freely to keep balance in the high-speed motion of the centrifugal disc 100, and the disc body 1 is prevented from falling out during high-speed centrifugation, so that the operation of the whole centrifugal machine is prevented from being influenced.

The cell-producing centrifuge can be configured to centrifuge a plurality of cell-producing clips on the centrifuge disk 100 at a time. The centrifugal tray 100 is provided with a plurality of centrifugal trays, and the bottom of the tray body 1 is provided with the balancing weights, so that the centrifugal tray is beneficial to improving the centrifugal speed and guaranteeing the stability of centrifugal movement, and meanwhile, two flaking clamps can be placed on one tray body 1, so that the physical structure of the centrifugal tray 100 is saved, more flaking clamps can be used for centrifugation at the same time, and the flaking efficiency is improved.
