The utility model provides a piston that can move freely up and down in the tube body, and removes the residual reagent on the inner wall of the tube body when pouring out the reagent, so that the measurement and inspection are more accurate. At the same time, scale lines and thermometers are provided on the tube body, which can not only measure accurately when used, but also measure the temperature of the solution in the test tube at the same time, and has stronger functionality. In the process of realizing the utility model, the inventor found that the prior art has the following problems:

[0004] This type of reagent pipette device has poor functionality. Although it removes the residual reagent on the inner wall of the tube body through the movement of the piston, improving the accuracy of measurement, it lacks an external pressing block plate or similar structure, which may lead to inconvenient operation. Secondly, the device is provided with scale lines and a thermometer on the tube body, which may increase the manufacturing cost and complexity although it is more functional. In addition, the device lacks consideration of structures such as folding hoses and clamping chambers, which may affect its practicality and stability.

[0005] Therefore, in view of the above problems, a reagent pipette for liquid to be tested is proposed for laboratory. Utility Model Content

[0006] In order to overcome the above defects of the prior art, the utility model provides a reagent pipette for test liquid for laboratory use to solve the problems raised in the above background technology.

[0008] Preferably, a foldable hose is movably connected to the surface of the device body.

[0009] Preferably, the bottom of the tube body cover is overlapped and connected with a stand.

[0010] Preferably, the liquid suction bag, the device body and the suction tube are arranged in an up-and-down arrangement, and a tube cover is nested on the surface of the suction tube.

[0011] Preferably, the embedded sliding piston is in the shape of a circular ring and is nested and distributed on the inner wall of the upper half of the device body, and is connected to the external pressing block plate to form a movable structure.

[0012] Preferably, the straw is in a shape of upper larger than lower and is nested and connected with the nested hollow cavity inside the tube body cover.

[0013] Preferably, the foldable hose is in a folded corrugated shape and can be flexibly folded up and down to overlap.

[0014] Preferably, the bottom of the stand is in the shape of a disc base, and the top is connected to the bottom of the tube body cover, forming an upper and lower structure.

[0015] Technical effects and advantages of the utility model:

The scale tightly fitted on one side of the device body allows the user to accurately measure the volume of the sucked test liquid reagent to ensure the accuracy of the experiment. The nested connection between the pressing piece and the external pressing block plate allows the user to easily control the expansion and contraction of the suction bag, thereby facilitating the suction and release of the test liquid reagent. The embedded sliding piston ensures the smooth flow of the test liquid reagent in the pipette. The pipette at the bottom of the device body is used to transport the test liquid reagent, and the movably connected tube body cover effectively prevents the leakage of the reagent. The design of the nested hollow cavity and the clamping cavity not only enhances the stability of the device, but also facilitates the user to fix and carry the pipette. The addition of the foldable hose provides the pipette with greater flexibility and durability. The overall structural design is reasonable and highly functional, which not only ensures the accuracy of the experiment but also improves the convenience of operation.
