Product features

Dropping funnel is made of high borosilicate glass, which has low expansion rate, high temperature resistance and corrosion resistance, high strength, high hardness, high light transmittance, and good heat resistance and chemical stability.

Dropping funnel is made of thickened glass, which is strong and durable, with fine workmanship and smooth surface; it has good light transmittance, high transparency, and is beautiful in appearance; the piston is flexible, can rotate freely, and is sealed and leak-proof; it has a standard ground mouth, fine frosting, and good sealing performance.

The main function of the dropping funnel is to achieve precise liquid dripping. In chemical experiments, for some experiments that require slow addition of reagents to control the reaction rate, the dropping funnel can provide very accurate dripping control. For example, in a synthesis reaction, slowly adding a reactant through a dropping funnel can avoid danger caused by too violent a reaction, and can also better control the progress of the reaction and the quality of the product.Since the dropping funnel is equipped with a cock, the cock can be closed in time during the reaction to prevent liquid back-sucking caused by changes in external air pressure. For example, in some experiments that generate gas or heat, when the air pressure in the reaction system decreases, if there is no anti-suckback function of the dropping funnel, the liquid in the reaction container may be sucked back into the dropping funnel, thus damaging the experiment or even Causing danger. The stopcock of the dropping funnel can be quickly closed in this case to protect the safety of the experiment.

Product applications

Wide applicability: Dropping funnels are widely used in laboratories in chemistry, pharmaceuticals, scientific research and other fields. In experiments such as organic synthesis, analytical chemistry, and drug development, dropping funnels are indispensable experimental instruments. For example, in the pharmaceutical industry, it is used for precise feeding and reaction control in the drug synthesis process; in scientific research experiments, it is used for various complex chemical reactions and separation operations, provides an important guarantee for the success of the experiment.

Versatility: In addition to being used for liquid dropping, the dropping funnel can also be used as a feeding device for adding solid powder or other substances to the reaction system. Precise control of the reaction can be achieved by placing the solid substance into a dropping funnel and then controlling its addition speed by adjusting the cock. In addition, the dropping funnel can also be used for separation and extraction operations. For example, in extraction experiments, the dropping funnel can be used to separate liquids of different densities into layers and collect them separately.
