Product features
Pear-shaped separatory funnel is made of high borosilicate glass material, low expansion rate, high temperature resistance and corrosion resistance, high strength, high hardness, high light transmittance, good heat resistance and chemical stability.
Pear-shaped separatory funnel is made of thickened glass, durable, fine workmanship, smooth surface; good light transmittance, high transparency, beautiful and elegant; flexible piston, PTFE piston can rotate freely, corrosion-resistant, sealed and leak-proof; standard grinding mouth,delicate frosted and good sealing.
Pear-shaped design is narrow at the top and wide at the bottom. This structure makes the layered interface of liquids clearer during the liquid separation process, makes it easy to observe and accurately separate liquids of different phases. The neck of the pear-shaped separatory funnel is shorter. Compared with the spherical separatory funnel, the pear-shaped separatory funnel has a shorter neck, which is more convenient to operate during use. Especially during extraction operations, it can better control the outflow speed and flow rate of the liquid. It is not easy for liquid splashing and other situations to occur.It can accurately separate two immiscible liquids. During the liquid separation operation, due to its special structural design and piston control, according to the density difference of the liquid, the piston can be opened first to release the lower liquid, and then the upper liquid can be poured out from the top of the funnel after closing the piston, thereby achieving efficient and accurate separation. liquid effect.For example, in the separation experiment of organic solvents and water, the separatory funnel can separate the two very well. In some chemical reactions that require controlling the dripping speed of liquid, the separatory funnel can be used as a liquid adding device. By adjusting the piston, the rate of liquid addition is controlled, thereby controlling the speed of the reaction. For example, in some slow reaction experiments, slowly adding reactants through a separatory funnel can better observe the reaction process and control the reaction conditions.
