Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of chemical experiment equipment, concretely relates to a support and measuring cup for water bath device. TECHNICAL BACKGROUND

[0002] Water bath heating is widely used in various experiments requiring constant temperature heating due to its uniform and stable temperature characteristics. In many experiments, in order to improve the uniformity and completeness of the reaction, water bath heating is often combined with stirring process. In specific operation, the water bath pot is usually placed on the iron stand, and the electric stirrer is fixed on the iron stand through the cantilever, and the stirrer is located above the water bath pot to ensure that the solution is heated while being uniformly stirred. However, the existing operation mode has certain limitations, especially in experiments requiring simultaneous addition of multiple solvents or reagents. Conventional liquid sampling tools, such as rubber head droppers, pipettes and pipetting guns, can achieve quantitative liquid sampling, but have low precision, long time consumption and cannot meet the requirements of large-scale rapid addition. In particular, in experimental scenarios requiring high precision, large quantities or simultaneous addition of multiple solvents, the operation efficiency is low and cannot meet the experimental requirements.

[0003] Currently, there are some automatic addition devices on the market that can batch and quantitatively add solutions, such as the quantitative solution automatic addition device disclosed in patent number CN218222492U, which can batch and quantitatively add liquids to meet the demand for quantitative addition. However, these devices are usually not suitable for water bath stirring experimental environment. Due to the presence of the stirrer, the existing automatic addition device often cannot be used normally under the condition of water bath stirring, so it cannot provide an effective solution in experiments requiring simultaneous liquid addition and stirring. Therefore, there is an urgent need for a new quantitative and constant-speed addition device that can overcome the limitations of existing equipment under the condition of water bath heating and stirring, achieve simultaneous quantitative addition of multiple solvents, and improve experimental efficiency and ensure experimental accuracy.
