[0044] (1) First, the volume needs to be calibrated before use and the calibrated volume should be marked on the scale line. Figure 7 The figure is a schematic diagram of a movable piston absorbing liquid medicine volume according to an embodiment of the utility model. Figure 7 As shown, the movable piston 5 is Figure 7 The position in the left figure is the lowest position, at which the constant volume bar 13 is at the 0 ml scale line; the movable piston 5 is at Figure 7 The volume corresponding to the scale line in the right figure is Vml, and the movable piston can inhale a volume of V 移 ml, the volume of the solution sucked by the pipette 7 inside the reaction container 1 is V 吸液管 ml; the calibration calculation formula is as follows:

[0045] V=V 移 -V 吸液管

[0046] (2) Then, add the sample to be tested: place the reaction container 1 on the placement rack 2, as shown in FIG. Figure 2 As shown, unscrew the sealing cover 10 on the sample adding port 9, add the liquid or solid sample to be tested through the sample adding port 9, dissolve or dilute the sample according to the analytical method, and tighten the sealing cover 10.

[0047] (3) Adjusting the inhaled volume: Rotate the constant volume nut 19 and move the constant volume bar 13 to the desired volume scale Vml.

[0048] (4) Aspirate the solution to complete the mixing reaction process: Install the pipette tip 8 and move the movable piston 5 to the 0 ml mark. Figure 7 In the left picture, hold the reaction vessel 1 in one hand, immerse the pipette tip 8 into the solution, and use the other hand to move the movable piston 5 upward to the position of the constant volume bar 13. The constant volume bar 13 limits the movable piston 5 to this point and cannot move up any further. At this time, the solution is sucked into the reaction vessel 1 through the pipette tip 8 and the pipette 7, and then the movable piston 5 is moved downward to the 0 ml mark. Gently shake the solution in the reaction vessel 1 so that the sample and the solution are evenly mixed and react. When inhaling the second solution, remove the used pipette tip 8, reinstall a new pipette tip, and absorb the second solution according to the previous steps of absorbing the solution. The third, fourth... and so on. After adding various solutions, the mixing reaction process is over.

[0049] (5) Reactor cleaning: After the test, unscrew the sealing cover 10, pour out the solution in the reaction vessel 1 from the sample injection port 9, and wash it with tap water for 3-5 times, and then wash it with deionized water for 2-3 times.

[0050] (6) Cleaning of the pipette: The pipette tip 8 can be disposable or can be cleaned and reused. The pipette 7 can be cleaned by tightening the sealing cover 10, moving the movable piston 5, and repeatedly filling and draining the liquid to clean it with tap water and deionized water.

[0051] As can be seen from the above description, the embodiment of the utility model provides a laboratory reactor device with adjustable liquid suction and addition function, which has the following advantages compared with the prior art:

[0052] 1) The volume of the aspirated solution is adjustable.

[0053] 2) The same instrument can be used to absorb different liquid medicines.

[0054] 3) The absorption of the drug solution and the chemical reaction are carried out in only one instrument.

[0055] 4) After the experiment, only the reaction vessel body needs to be cleaned, which reduces the number of cleaning instruments and reduces the workload.
