Embodiment 1

[0024] Such as Figure 1-3 As shown, a titration auxiliary device for preventive medicine experiments provided by the present invention includes: a bracket 101, a half-ring sleeve 105, a light sensor plate, a red light emitter 108 and a controller. The bracket 101 includes two opposite columns 103, Both columns 103 are provided with a vertical chute 104, and the burette 102 is fixed on the column 103; one end of the half ring sleeve 105 is provided with a first slider 106, and the other end of the half ring sleeve 105 is provided with a second slider 107, the first slider 106 is slidably connected with the chute 104 on one column 103, the second slider 107 is slidably connected with the chute 104 on the other column 103, and the half ring sleeve 105 is connected with a lifting device; the light sensor plate It is connected with the first slider 106; the red light emitter 108 is connected with the second slider 107, the red light emitter 108 is directly opposite to the light se...

Embodiment 2

[0029] On the basis of Embodiment 1, in order to complete the titration experiment, the lifting device drives the red light emitter 108 to move down to when the clustered red light generated by the red light emitter 108 irradiates the liquid level position of the indicator in the burette 102, The controller automatically controls the lifting device to stop driving.

[0030] As shown in FIG. 4 , wherein the light sensing board includes a substrate 201 and a plurality of light sensors 202, the substrate 201 is connected to the first slider 106, and the light sensors 202 are arranged in a matrix with the substrate 201, the clustered red light generated by the red light emitter 108 can pass through the burette 102 and irradiate on one of the light sensors 202 of the light sensor plate and make the light sensor 202 respond. When the sensor 202 changes, the controller controls the lifting device to change the motion state.

[0031]After the titration experiment is completed, the co...

Embodiment 3

[0033] On the basis of Example 2, in order to carry out the liquid flow operation before the titration experiment, when the liquid level of the indicator in the burette 102 is located at the scale position where the clustered red light irradiates on the burette 102, the experimenter can be instructed , to assist the experimenter to close the burette 102.

[0034] Such as figure 2 As shown, wherein, the half-ring sleeve 105 is also provided with a color-changing lamp bead 3, and the color-changing lamp bead 3 is electrically connected to the controller. When the light sensor 202 responding on the light sensor board changes, the control The controller controls the discoloration of the color-changing lamp bead 3 .

[0035] Before carrying out the titration experiment, when performing liquid flow operation, when the indicator liquid level arriving in the burette 102 is located at the scale position where the clustered red light irradiates on the burette 102, the refractive index...

Abstract

The invention discloses a titration auxiliary device for a preventive medicine experiment, and belongs to the technical field of experimental equipment. The titration auxiliary device for the preventive medicine experiment comprises a support, a semi-ring sleeve, a light sensing plate, a red light emitter, a display and a controller; the support comprises two oppositely-arranged stand columns, the two stand columns are provided with vertical sliding grooves, and burettes are fixed to the stand columns; a first sliding block is arranged at one end of the semi-ring sleeve, a second sliding block is arranged at the other end of the semi-ring sleeve, and the semi-ring sleeve is connected with a lifting device ; clustered red light of the red light emitter can penetrate through the burettes and irradiate the light sensing plate ; and the controller is electrically connected with the lifting device, the light sensing plate, the red light emitter and the display, and the controller is electrically connected with a counting module. The titration auxiliary device for the preventive medicine experiment can assist an experimenter in reading the volume of an indicator consumed in the burette after the titration experiment is completed, so that the experimenter can conveniently measure and calculate the content of reactants in a solution contained in the container.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a titration auxiliary device for preventive medicine experiments. Background technique [0002] Titration experiments are commonly used in medical or chemical experiments for quantitative analysis of the solute content in a solution. The content of a certain reactant is determined by using an indicator to quantitatively react the reactant solute in the solution. Titration experiments need the help of burettes, containers and other auxiliary devices to complete the titration experiments. [0003] The existing titration auxiliary device lacks the function of assisting the experimenter to read the volume of the indicator consumed in the burette after the titration experiment is completed, and the experimenter needs to read and calculate the volume of the indicator consumed in person, which is not only inconvenient to use , and prone to problems such as reading errors...
