Product features

Cylindrical constant pressure separatory funnel is a commonly used glass instrument in the laboratory, mainly used for separation and extraction of liquids and accurate control of the dripping speed and dosage of liquid reagents in chemical reactions. It is generally made of high borosilicate glass and has good chemical stability, thermal stability and transparency. Its unique constant pressure design is usually connected to the outside atmosphere through a side branch pipe, so that the pressure inside the funnel is always consistent with the outside world, ensuring that the liquid can drip smoothly without being affected by the pressure changes in the system.The standard ground mouth design is convenient for connecting with other standard ground mouth glass instruments, such as flasks, condensers, etc., to assemble various complex experimental devices, and the connection is tight and the sealing is good, which can effectively prevent liquid leakage and gas escape. In addition, the flow rate and flow of the liquid can be accurately controlled by rotating the piston to meet the precise requirements of different experiments on the amount of liquid added.

The constant pressure design of the cylindrical constant pressure separatory funnel balances the internal and external pressures through structures such as side tubes, ensuring that the liquid flows smoothly, preventing back suction, and facilitating accurate measurement of gas volume. It can be used for liquid-liquid separation, extraction and other operations, and can accurately control the liquid flow rate and amount.

Product applications

(1) Chemical experiments: In organic synthesis, inorganic synthesis and other experiments, it is used to accurately control the dripping speed and dosage of liquid reagents to control the reaction process and improve the reaction yield.

(2) Separation and purification: Using its liquid separation function, it can separate immiscible liquid mixtures, such as separating oil and water from oil-water mixtures; it can also be used for extraction operations to extract target substances from mixtures.

(3) Gas preparation: In some gas preparation experiments, liquid reactants can be dripped into the reaction vessel through a constant pressure separatory funnel, while balancing the system pressure to ensure the safety and smooth progress of the experiment.
