Description

Technical Field

[0001] The invention relates to the field of experiments, in particular to a light-shielding dripping device. Background Art

[0002] Plant tissues usually need to be stained before observation. The dyes used in the staining process are easily decomposed by light, so they usually need to be shielded from light during staining. When the existing dyes are dripped into the centrifuge tube containing the plant tissues, in order to avoid dye photolysis, they usually need to be carried out in a weak light environment. However, it is difficult to find a suitable environment for staining operations when conducting outdoor experiments, so a device that can easily achieve light-shielding dye dripping is needed. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a light-shielding drip dyeing device.

[0004] The solution of the present invention to solve its technical problem is:

[0005] A light-shielding drip-dyeing device comprises a light-shielding cavity, the cavity wall of the light-shielding cavity is made of an opaque material, a dripping port is arranged on the top surface of the light-shielding cavity, a clamping arm is arranged on the cavity wall of the light-shielding cavity, a clamping opening is arranged at one end of the clamping arm away from the cavity wall of the light-shielding cavity, and the clamping opening is located below the dripping port; the light-shielding cavity is formed by at least two detachably connected parts being spliced ​​together.

[0006] The beneficial effect of the present invention is that before use, the two parts of the light-shielding chamber are in a separated state. When in use, the centrifuge tube containing the plant tissue to be colored is first placed on the clamp, and then the two parts are connected to form the light-shielding chamber, and the entire drip dyeing device is kept as vertical as possible, and then the dropper containing the dye is extended to the light-proof position below the dripping port, and the dye is dripped into the centrifuge tube, thereby realizing the operation of dripping the dye in the light-shielding state.

[0007] After the dye dripping operation is completed, in order to improve the dyeing effect, the dyeing process is preferably carried out in a light-shielded state. When the external light source can be emitted from the dripping port to the inside of the light-shielding cavity, the dripping port can be light-shielded by inserting a dropper on the dripping port to close the dripping port or other methods.

[0008] It is understandable that the above uses a light-proof dropper. In addition, preferably, the clamping arm is made of plastic material, so that the clamping mouth has a certain deformation ability, and the centrifuge tube can slide out or slide in along the side wall direction of the clamping mouth, which makes the centrifuge tube clamping more convenient. The light-proof material can specifically be PP, PBT, etc., or made of a material coated with a light-proof coating on the surface.

[0009] The overall size of the dripping and dyeing device is specifically made slightly larger than that of a centrifuge tube, making it convenient to carry and facilitating light-shielding dripping and dyeing in an outdoor environment.

[0010] Furthermore, a cut is provided on the cavity wall of the light-shielding cavity. The cut is located above the clamping opening. A flexible wall is provided at the cut. The flexible wall is connected to the cavity wall of the light-shielding cavity and closes the cut. The area of the flexible wall is larger than that of the cut, such that the flexible wall can extend into the interior of the light-shielding cavity. The beneficial effect of adopting the further technical solution is that when a centrifuge tube with a gland is used, the setting of the flexible wall enables the hand to reach inside the light-shielding cavity to close the gland and seal the upper end of the centrifuge tube, and the content of the centrifuge tube is not likely to fall out when the dripping and dyeing device moves. The flexible wall can specifically be made of a flexible material such as cloth, or made of an elastic material such as silica gel or rubber.

[0011] Furthermore, there are two parts of the split body, namely a left split body and a right split body. The left split body is connected to the right split body into one body by means of plugging. Connecting together by means of plugging has the advantage of being convenient for assembly and disassembly.

[0012] Furthermore, the left split body is in a "U" shape with an opening to the right. A bottom support is provided on the lower side of the left split body. The bottom support is located below the clamping arm. A slot is formed between the bottom support and the bottom wall of the left split body. The left side of the right split body is provided with a lower insertion plate and an upper insertion plate that both extend leftward. The lower insertion plate is inserted into the slot, and the top surface of the upper insertion plate abuts against the left split body. The beneficial effect of adopting the further technical solution is that the setting of the bottom support enables the lower side of the centrifuge tube clamped in the clamping opening to have positioning, and the lower insertion plate inserted into the slot can enable the insertion plate to have a better fixing effect.

[0013] Furthermore, a ring-shaped connecting bone is provided at the liquid dripping port. The connecting bone is fixedly connected to the upper side wall of the light-shielding cavity and extends upward. A threaded section is provided on the inner side of the connecting bone. The light-shielding dripping and dyeing device further includes a dropper. The dropper is made of a light-impermeable material. The dropper includes a liquid storage tube and a liquid supply piston. A threaded section is also provided on the lower side of the liquid storage tube. The lower side of the liquid storage tube is threadedly connected to the connecting bone. The liquid supply piston is slidably connected in the liquid storage tube in a sealed manner. Scale lines are provided on the outer side wall of the liquid supply piston. The lower side of the liquid storage tube is communicated with the liquid dripping port. The beneficial effect of adopting the further technical solution is that on the one hand, the dye is stored in the dropper and the liquid supply is carried out by the liquid supply piston with scale lines, and the amount of the dropped dye is relatively accurate. On the other hand, the dropper and the liquid dripping port are connected into one body through the connecting bone, which can enable the dropper and the liquid dripping port to be connected into one body to shield the liquid dripping port, and they are not likely to scatter when transferred.
