Second, when the test tube body is placed inside the storage ring, the bottom surface of the blocking ring will fit with the top surface of the storage ring, and the limiting column will enter the limiting groove to prevent the test tube body from rotating inside the storage ring during the test. When the test tube body is placed inside the storage ring, the experimenter will push the sliding plate toward the center of the storage ring, and then push the sliding plate to the top surface of the blocking ring, so as to prevent the test tube body from sliding from the inside of the storage ring when it is placed in an inclined position, thereby increasing the safety of the test tube body when in use;

3. The beaker for pouring chemical reagents from the test tube body will be placed inside the placement port, which limits the stability of the position of the beaker below the test tube body and prevents the beaker from being displaced by the poured reagents. When pouring the chemical reagents in the pipetting test tube body, the chemical reagents will pour out through the drainage groove, which converges the poured water flow and prevents the poured chemical reagents from splashing everywhere.
