Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical testing technology, specifically to an analytical titration device for pharmaceutical testing. Background Technology

[0002] Titration is a quantitative analytical technique and a chemical experimental procedure. It determines the content of a solute by the quantitative reaction between two solutions. The endpoint is indicated by the color change of an indicator, the volume of standard solution consumed is visually estimated, and the analytical result is calculated.

[0003] Chinese invention patent application number 202110079931.5 discloses a multi-compartment burette based on an adjustment component for convenient titration of various reagents, including a riser; the riser has a first compartment, a second compartment, and a third compartment respectively; a volume scale is fixedly connected to the side of an arc-shaped riser; an annular internal toothed ring is fixedly connected to the upper surface of a T-shaped slider; a toothed structure is fixedly connected to the side of the arc-shaped riser near the bottom; the circumferential side of the toothed structure meshes with the inner circumferential side of the annular internal toothed ring; a first burette, a second burette, and a third burette are respectively opened at the bottom of the riser. This device, through the design of the first compartment, the second compartment, the third compartment, the third annular groove, and the inclined rod, can simultaneously fill multiple reagents and meet different titration requirements, greatly improving the efficiency of titration experiments and effectively avoiding experimental failures caused by untimely titration. The device has its own support function and does not require the use of an iron stand.

[0004] After improvement, the aforementioned device, through the design of the first compartment, second compartment, third compartment, third annular groove, and inclined rod, can simultaneously fill multiple reagents and meet different titration requirements, greatly improving the efficiency of titration experiments. During titration experiments, the titration volume needs to be controlled by controlling the valve on the burette, and generally only one titration reagent can be filled. When multiple reagents need to be used for titration simultaneously, the common operation is to constantly change the burette on the iron stand, which is cumbersome and inefficient, and may lead to experimental failure due to untimely titration, delaying the detection progress. Therefore, we propose an analytical titration device for pharmaceutical testing. Utility Model Content

[0013] This invention provides an analytical titration apparatus for pharmaceutical testing, which has the following advantages:

[0014] 1. This analytical titration apparatus for pharmaceutical testing uses a motor to drive a rotating disc. The disc's rotation, in turn, drives a transmission shaft. Since the transmission shaft is not located at the center of the disc, it rotates around the disc and along a sliding groove inside the disc. This rotation, combined with the sliding groove, drives the rotating disc, causing the burette positioned above the beaker to change position. This eliminates the need to disassemble and reinstall the burette, effectively solving the problem of frequent burette replacements, simplifying the operation, preventing experimental failures due to untimely titration, and improving testing efficiency.

[0015] 2. This analytical titration apparatus for pharmaceutical testing, through the combination of a connecting rod, a through groove, and an L-shaped locking block, allows for adjustment of the position of the burette and the burette holder. This enables flexible adjustment based on the length of the burette, facilitating testing experiments and improving the flexibility of use. Attached Figure Description

A drive shaft 17 is fixedly installed at one end of the disc 15. A sliding groove 19 is opened inside the rotating disk 16, and the drive shaft 17 is located inside the sliding groove 19 and slidably connected to it. Multiple adjusting rods 8 are fixedly installed on the top of the rotating disk 16. A burette 13 is provided at one end of each adjusting rod 8. The rotation of the disc 15 drives the drive shaft 17 to rotate. Through the cooperation of the drive shaft 17 and the sliding groove 19, the rotating disk 16 rotates. When one burette 13 has completed titration, the other burette 13 is moved above the beaker 21 for titration, thereby improving the detection progress.

[0023] An electronic scale 20 is fixedly installed on the top of the operating frame 1. A beaker 21 is placed on top of the electronic scale 20. The beaker 21 is used in conjunction with the electronic scale 20 and the burette 13. By placing the beaker 21 above the electronic scale 20, it can be weighed, which facilitates the user's testing. A display 2 is set on the top of the operating frame 1. The display 2 is used in conjunction with the electronic scale 20.
