Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical testing technology, specifically a pharmaceutical testing and analysis titration device. Background Technology

[0002] There are numerous testing items in pharmaceutical testing, including pharmaceutical quality testing, pharmaceutical component testing, pharmaceutical heavy metal testing, pharmaceutical adverse reaction testing, pharmaceutical sealing testing, biological drug testing, pharmaceutical appearance testing, routine pharmaceutical testing, pharmaceutical physicochemical testing, pharmaceutical safety testing, and pharmaceutical defect testing. Pharmaceutical testing usually uses titration for quantitative analysis. Titration is a quantitative analysis method and a chemical experimental operation. It determines the content of a certain solute through the quantitative reaction of two solutions. It uses the color change of an indicator to indicate the titration endpoint, then visually measures the volume of standard solution consumed, and calculates the analytical results.

[0003] In existing technologies, during the use of titration devices in pharmaceutical testing and analysis, it is inconvenient to adjust the clamping position of the burette, which makes it impossible to vertically fix burettes of different lengths and sizes, thus affecting the accuracy and ease of operation of the titration.

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the above and / or existing problems in drug testing, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a titration device for pharmaceutical testing and analysis, which can facilitate the vertical fixation of burettes of different lengths and sizes by adjusting the clamping position of the burette during the titration process, making them more stable and thus improving the accuracy and ease of operation of titration.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] This utility model provides a titration device for pharmaceutical testing and analysis. Please refer to [link / reference]. Figures 1-4The system includes an operating table 100 and a fixed frame 200. A placement base 110 and a stand 120 are fixedly mounted on the top of the operating table 100. A first linear motor 130 is embedded in the side wall of the stand 120. A movable frame 140 is fixedly connected to the moving end of the first linear motor 130. The fixed frame 200 is fixedly mounted on the right side wall of the movable frame 140. A sliding groove 210 is formed in the side wall of the fixed frame 200, and a bidirectional screw 220 is rotatably connected within the sliding groove 210. A knob 230 is rotatably connected to the top of the fixed frame 200. One end of the screw is fixedly connected to the knob 230. A slider 240 is threaded onto the side wall of the bidirectional screw 220. A clamping seat 250 is connected to the side wall of each slider 240. A mounting hole 260 is provided on the side wall of the clamping seat 250. A pull rod 270 is slidably connected within the mounting hole 260. A pressure block 280 is fixedly connected to one end of the pull rod 270. A spring 281 is connected to the inner wall of the clamping seat 250. One end of the spring 281 is connected to the side wall of the pressure block 280. A burette 290 is embedded between the pressure block 280 and the inner wall of the clamping seat 250. Specifically, the conical flask is placed in the placement seat 110, which limits the position of the flask. The conical flask is used to hold the solution to be titrated. The moving end of the first linear motor 130 drives the moving frame 140 to move up and down, adjusting the height of the burette 290 to facilitate the insertion of the burette tip into the mouth of the conical flask. The knob 230 allows the bidirectional screw 220 to be rotated, thereby pushing the two sliders 240 to move relative to each other. The two sliders 240 respectively drive the two clamping seats 250 to move closer together or further apart. The distance between the two clamping seats 250 is easy to adjust, so that the clamping position can be flexibly adjusted according to the different lengths of the burette 290. The pull rod 270 can easily pull the pressure block 280 to embed the burette 290 between the clamping seat 250 and the pressure block 280. The spring 281 rebounds and causes the pressure block 280 to press against the side wall of the burette 290. The pressure block 280 clamps and fixes the burette 290 between the clamping seat 250 and the pressure block 280, which facilitates the vertical fixation of the burette 290 and makes it easy to install and remove.

[0027] A rubber pad is provided at the bottom of the operating table 100. The rubber pad is bonded to the bottom of the operating table 100. Specifically, the rubber pad increases the friction at the bottom of the operating table 100 and improves the anti-slip properties of the device.

[0028] The front wall of the control panel 100 is equipped with a control panel, which is fixedly connected to the front wall of the control panel 100 by bolts. Specifically, the control panel facilitates the operation and adjustment of the first linear motor 130.

[0029] Anti-slip pads are symmetrically arranged on the inner walls of the clamping seat 250 and the pressure block 280. The anti-slip pads are bonded to the inner walls of the clamping seat 250 and the pressure block 280. Specifically, the anti-slip pads help to increase the friction when the burette 290 is clamped, thereby improving the clamping stability.

[0030] The placement seat 110 is located below the burette 290, which makes it easier for the burette 290 to titrate liquid into the conical flask, thus facilitating operation.

[0031] The pressure block 280 is slidably connected to the inner wall of the clamping seat 250, which facilitates the clamping and fixing of the burette 290 between the pressure block 280 and the clamping seat 250.

[0032] Combination Figures 1-4 The specific usage process of the titration apparatus for pharmaceutical testing and analysis according to this embodiment is as follows: During the titration process, the conical flask is placed in the placement seat 110, which limits the position of the flask. The conical flask is used to hold the solution to be titrated. As needed, the double-ended screw 220 is rotated using the knob 230, thereby pushing the two sliders 240 to move relative to each other. The two sliders 240 respectively drive the two clamping seats 250 to move closer or further apart, adjusting the distance between the two clamping seats 250. This allows for flexible adjustment of the clamping position according to different lengths of the burette 290. The pressure block is pulled using the pull rod 270. 280. The burette 290 is embedded between the clamping seat 250 and the pressure block 280. The spring 281 rebounds and causes the pressure block 280 to press against the side wall of the burette 290. The pressure block 280 clamps and fixes the burette 290 between the clamping seat 250 and the pressure block 280, which facilitates the vertical fixation of the burette 290, making it more stable and improving the accuracy and ease of operation of the titration. It is also convenient for installation and disassembly. The first linear motor 130 is used to drive the moving frame 140 to move up and down to adjust the height of the burette 290, so that the tip of the burette 290 can be inserted into the mouth of the conical bottle, which facilitates the titration operation.

Specifically, the second linear motor 300 facilitates the up-and-down movement of the connecting frame 310, thereby facilitating the up-and-down movement of the cover plate 320, making it easy to adjust the height of the cover plate 320 so that the cover plate 320 covers the conical flask. The cover plate 320 can prevent liquid splashing during titration, reducing reagent waste and experimental errors. The through hole 330 facilitates the insertion of the burette 290 tip into the container mouth for titration operations.
