Description

Technical Field

[0002] Chemical reagents usually refer to high-purity chemicals used in chemical reactions, analytical tests, research experiments, teaching demonstrations, and chemical formulations. Before using these reagents in experiments or production, they usually need to be weighed independently, and after weighing, they are mixed or diluted with other substances according to specific ratios and methods to ensure the accuracy and safety of the experiment or reaction. This process is called reagent preparation.

[0003] After a large number of searches, the publication number is CN221506102U, which discloses a chemical reagent reaction ingredient preparation device. By setting the slot and socket to be clamped and matched, the tray is connected to the placement rack. The clamped connection method is convenient for inserting the tray and can effectively avoid the situation of the tray tipping due to external force. And through the opened connection groove as the material discharge port, after quantitative weighing, it is discharged through the connection groove, which is convenient for subsequent operations and does not require removing the tray from the weighing platform.

[0004] However, chemical reagents include liquid reagents and solid reagents. The above device can conveniently weigh solid reagents during use. However, when weighing liquid reagents, it still needs to rely on beakers or test tubes as storage media to weigh the reagents. When placing test tubes or beakers on the above device, the weighing result may be inaccurate due to the offset of the placement position. At the same time, since most liquid reagents have certain corrosiveness, there is a risk of splashing during weighing and liquid addition. The splashed reagents are likely to cause injury to personnel. Therefore, a chemical reagent reaction ingredient preparation device is proposed to solve the above problems.
