[0002] Test tubes are commonly used instruments in chemical laboratories. They are used as reaction containers for small amounts of reagents. They are used at room temperature or when heated (they should be preheated before heating, otherwise the test tubes are prone to bursting). Test tubes are divided into ordinary test tubes, supported test tubes, centrifugal test tubes, etc. Test tube racks are used to place (sometimes test tubes can also be placed on test tube racks to observe the phenomenon of a certain experiment) and dry test tubes. They are the most basic experimental instruments in chemical laboratories. The test tube racks are equipped with a corresponding number of small wooden columns and small holes. The test tubes with small holes can be placed upright for standby use or to continue observing the progress of the reaction. The cleaned test tubes can be turned upside down to dry. The test tube rack is a kind of chemical experimental instrument. It is a wooden rack or a bamboo rack with 6 holes and 12 holes. The colorimetric analysis method uses the color of the solution to be tested, or the color after adding reagents, to observe and compare the color depth of the solution with the eyes (or visual colorimeter), or to measure with a photoelectric colorimeter to determine the concentration of the substance to be tested in the solution. The colorimetric method includes visual colorimetry and photoelectric colorimetry. When performing colorimetric analysis on the solution in the test tube, the test tube needs to be removed from the test tube rack for colorimetric analysis;

When the color paper 19 is installed, the scrapers 35 are used to scrape the surface of the color paper 19 flat to prevent the wrinkles of the color paper 19 from affecting the colorimetric analysis. A corner block 34 is fixedly connected to one side of the fixing frame 33, and the corner block 34 is provided to fold the color paper 19 to prevent the shape of the color paper 19 after installation from being inconsistent with expectations.

[0039] In one embodiment, in order to facilitate light shielding protection of the solution in the test tube when needed, baffles 15 are provided on both sides of the mounting frame 11, and first fixing bolts 16 are threadedly connected to one side of the baffle 15 at equal intervals, and screw holes 37 are symmetrically opened on one side of the mounting frame 11 and the support frame 17.

[0040] The positioning mechanism 20 includes a mounting plate 21, a placement seat 22 and a rubber sleeve 25. One side of the support frame 17 is fixedly connected to the mounting plate 21, and one side of the mounting plate 21 is fixedly connected to the mounting frame 11. The support frame 17 supports one side of the mounting plate 21 to enhance the stability of the mounting plate 21. The placement seats 22 are equidistantly distributed on one side of the mounting plate 21 for placing test tubes. The rubber sleeve 25 is fixedly connected to the inside of the placement seat 22.

When the color paper 19 passes the fixing frame 33, the color paper 19 is scraped. The plate 35 scrapes and flattens the surface of the color paper 19, and the folding block 34 folds the color paper 19 to make the color paper 19 fit more closely to the mounting frame 11. The color paper 19 is used as the background color for colorimetric analysis of the solution in the test tube. When comparative analysis between solutions is required, the placement seat 22 is moved to make the placement seat 22 cooperate with the sliding sleeve plate 23 to slide in the slide groove 24, and the positions of the placement seat 22 and the test tube are adjusted. There is no need to take out the test tube and reinstall it. When the solution needs to be protected from light, the baffle 15 is fixed to both sides of the mounting frame 11 with the first fixing bolt 16 to provide side light protection for the solution in the test tube.
