Description

Technical Field

[0001] The present application relates to the technical field of cleaning experimental pipettes, and in particular to a pipette wall cleaning device. Background Art

[0002] A pipette is a measuring instrument used to accurately transfer a certain volume of solution. It is an indispensable tool in the laboratory. It is usually only used to measure the volume of the solution it releases, so it is a measuring instrument. The pipette is usually made of glass, with a bulge in the middle, a pointed mouth at the bottom, and a mark engraved on the neck of the upper end to indicate the exact volume taken. Pipettes have multiple applications in the laboratory, including accurately controlling the volume of samples added, mixing and stirring solutions, distributing and evenly arranging samples, transferring and collecting liquids, etc. Pipettes can easily transfer liquids from one container to another, or collect liquids, thereby avoiding waste and contamination of liquids.

[0003] At present, pipettes are usually cleaned after use to prevent mixing of different reagents and affecting experimental results when used next time. However, since pipettes are usually small in diameter, when they are cleaned with water (faucet), only a small amount of water will enter the pipette, while more water will flow to the outside of the pipette, causing water waste (see the manual). Figure 1 If a smaller water flow is controlled ( Figure 2 As shown in the figure, the cleaning pressure is insufficient and the tube wall cannot be effectively cleaned. When it is used again in the future, there will be mixed contamination between different reagents. At the same time, during the cleaning process, the pipette is usually driven to shake up and down so that the cleaning water entering its inner cavity can fully contact the tube wall to achieve complete cleaning. When moving up and down, since the pipette is usually long, it is very easy for the end of the pipette to contact the operating table, etc., causing the pipette to break ( Figure 2 shown at the bottom). Summary of the invention

[0004] In response to the above-mentioned problems, the present application aims to provide a pipette wall cleaning device, which can be inserted into the pipette and direct water into the pipette, and output the water into the pipette through the cleaning end for cleaning, thereby avoiding the current problems of water waste and incomplete cleaning during cleaning.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a pipette wall cleaning device, characterized in that: the cleaning device can be fully extended into the pipette, and has a connecting end connected to a water source, and a cleaning end for outputting cleaning water. The cleaning device is also provided with a repeated cleaning structure for cleaning the pipette multiple times during a single penetration and cleaning process.

[0006] Preferably, the cleaning device is a cleaning capillary tube whose outer diameter is smaller than the inner diameter of the pipette and whose length is greater than the pipette, and the connecting end of the cleaning capillary tube is provided with a sleeve which can be mounted on the water source equipment.

[0007] Preferably, a hanging rope which can be hung on a water source device is connected to the side wall of the casing.

[0008] Preferably, the repeated cleaning structure is cleaning holes opened at intervals throughout the length of the wall of the cleaning capillary tube.

[0009] Preferably, the cleaning holes opened through the length are opened in a circumferentially staggered manner.

[0010] The beneficial effect of the present application is that the cleaning device can be extended into the pipette and water can be introduced into the pipette, and the water is output into the pipette through the cleaning end for cleaning, thereby avoiding the current problem of water waste during cleaning.

[0011] The repeated cleaning structure can achieve multiple cleaning of the same position on the tube wall, thereby improving the integrity of the pipette cleaning and solving the current problems of mixed contamination of different reagents caused by incomplete cleaning and the pipette being easily broken when shaking up and down for cleaning.

[0019] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0020] See attached Figures 1 to 6The pipette wall cleaning device shown in the figure can be extended into the pipette 1, and has a connection end connected to a water source, and a cleaning end for outputting cleaning water. During operation, the cleaning device is extended into the pipette 1, and its connection end is connected to a water source (such as a faucet), and water flow can be introduced into the pipette 1, and the water flow is output into the pipette 1 through the cleaning end for cleaning, thereby avoiding the current problem of water flow waste during cleaning.

[0021] In order to improve the cleaning effect, the cleaning device is also provided with a repeated cleaning structure for cleaning the pipette multiple times during a single penetration and cleaning process. That is, when the cleaning device penetrates and introduces water into the pipette wall, the repeated cleaning structure can realize multiple cleaning of the same position of the pipette wall, thereby improving the completeness of the cleaning of the pipette 1.

[0022] Specifically, Figure 3-4 As shown, the cleaning device is a cleaning capillary 2 whose outer diameter is smaller than the inner diameter of the pipette 1 and whose length is greater than the pipette 1. The connection end of the cleaning capillary 2 is provided with a sleeve 21 which can be sleeved on the water source equipment, and the bottom end of the cleaning capillary 2 is used as the cleaning end. During the cleaning operation, the sleeve 21 can be connected to the water source equipment (such as a faucet), and then the cleaning end of the cleaning capillary 2 is inserted from the top port of the pipette 1. During the insertion process, the faucet is turned on, and the water source enters the cleaning capillary 2 and is input from its bottom end. Under the action of water pressure, the pipette wall of the pipette 1 is effectively cleaned.

[0023] During the cleaning process, if a large water pressure from the faucet is used for effective cleaning, the large water pressure may easily cause the sleeve 21 to separate from the faucet and fall off. Therefore, in order to solve this problem, Figure 5 As shown, a hanging rope 3 that can be hung on a water source device is connected to the side wall of the sleeve 21. The cleaning capillary 2 is hung on the faucet by the hanging rope 3, which can effectively overcome the problem of the sleeve 21 being separated from the faucet and falling due to the large water flow pressure of the faucet, and ensure the smooth progress of the cleaning process.

[0024] Specifically, Figure 6 As shown, the repeated cleaning structure is cleaning holes 2a opened at intervals throughout the length of the wall of the cleaning capillary 2. Since the cleaning capillary 2 is gradually inserted into the pipette 1, water is sprayed from multiple cleaning holes 2a during the insertion process. After the water flow in the cleaning holes 2a on the lower side cleans the wall of the pipette 1, the cleaning holes 2a on the upper side clean the wall of the pipette 1 again during the downward movement of the cleaning capillary 2, thereby achieving multiple cleaning operations through the cleaning holes 2a during a single insertion of the cleaning capillary 2, thereby improving the cleanliness of the pipette wall cleaning.

[0025] To further improve the cleaning effect, Figure 6As shown, the cleaning holes 2a opened throughout the length are staggered in the circumferential direction, that is, the multiple cleaning holes 2a opened are staggered in the circumferential direction on the basis of being arranged along the length direction of the cleaning capillary 2, so that the cleaning holes 2a can completely clean the tube wall along the circumferential direction, thereby further improving the cleaning effect.

[0026] The principle of the present application is: during the cleaning operation, the sleeve 21 can be connected to a water source device (such as a faucet), and then the cleaning capillary 2 is hung on the faucet through the hanging rope 3, so as to overcome the problem of the sleeve 21 being separated from the faucet and falling due to the large water flow pressure of the faucet. Then the cleaning end of the cleaning capillary 2 is inserted from the top port of the pipette 1. During the insertion process, the water source is sprayed from multiple cleaning holes 2a. After the water flow in the cleaning holes 2a on the lower side cleans the pipette 1 wall, the cleaning holes 2a on the upper side clean the pipette wall again during the downward movement of the cleaning capillary 2, thereby realizing multiple cleaning operations through the cleaning holes 2a during a single insertion of the cleaning capillary 2, thereby improving the cleanliness of the pipette wall.

[0027] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
