About

A separatory funnel is most often used in laboratories to distinguish the densities between of 2 different liquids. It is made of high quality borosilicate glass. With Interchangeable plastic stopper and PTFE key stopcock. PTFE stopcock is generally more reliable than a glass stopcock.

The neck of the pear-type separatory funnel is relatively short, and is commonly used as an instrument for extraction operation. The use process includes leak detection, adding liquid, shaking, standing, liquid separation, washing, and the like. It is mainly used for solid-liquid or liquid-liquid reaction generating device to control the amount of liquid to be added and the reaction rate; the substance is separated and purified, and the mutually incompatible two liquids formed after the extraction are separated. Before use, check whether the plug and the piston core are matched with the separatory funnel.

How to Use Pear Shape Separating Funnel?

There is a piston at the neck of the parting funnel, which is the important reason why it is different from the ordinary funnel and the long-necked funnel. Because there is no piston at the neck of the ordinary funnel and the long-necked funnel, it cannot flexibly control the liquid. Before using the funnel, remove the plug core on the funnel neck and apply vaseline, but not too much, so as not to block the flow hole.Insert the separator funnel into the plug slot and rotate to make the oil film uniform and transparent, and rotate freely. Then close the cock, fill the funnel, check whether the cock is leaking, not leaking funnel can be used. The amount of liquid added to the funnel should not exceed three quarters of the volume. And should not hold alkaline liquid. To prevent impurities from falling into the funnel, the plug on the funnel should be covered. When used, the left hand hold up the funnel ball, with the thumb and forefinger rotating piston control add liquid. At this point, the small slot of the glass plug should be aligned with the small hole on the side of the funnel, before the smooth filling.

The piston can control the flow of liquid when the liquid in the parting funnel flows downward. If the reaction is to be terminated, the piston must be tightly closed. Therefore, the dripping liquid can be stopped immediately.When discharging liquid, the groove on the grinding plug should be aligned with the small hole on the neck of the funnel. At this time, the air inside and outside the funnel is connected with the same pressure, so that the liquid in the funnel can flow out smoothly.According to the principle of "upflow", open the piston to let all the lower liquid flow out, and close the piston.The upper layer is poured from the upper mouth.The parting funnel cannot be heated.The funnel should be washed after use.Wipe the cocks clean of separators that have not been used for a long time, put a strip of paper between the plug and the slot, and put a rubber band around the piston to prevent adhesion in the frosted area.
