There are many types of glass instruments, which can be roughly divided into containers, measuring instruments and other instruments according to their uses.

Containers include reagent bottles, beakers, flasks, etc. According to whether they can be heated, they can be divided into heatable instruments and not suitable for heating. Measuring instruments include measuring cylinders, pipettes, burettes, volumetric flasks, etc. Measuring instruments must not be heated.

Other instruments include glass instruments with special purposes, such as condenser tubes, separating funnels, dryers, fractionation columns, sand core funnels, standard grinding glass instruments, etc.

My advice is to look for a book, such as the Handbook of Laboratory Glass Instruments, or the Laboratory Book of Basic Chemistry, and you will know it right away.

This is called a separating funnel.

Separate funnels. It is a kind of glass experimental instrument, especially involving a separating funnel for chemical experiments. Including the bucket body, the bucket lid that covers the upper mouth of the bucket body. The lower mouth of the bucket body is provided with a piston of a three-way structure, and the two crosses of the piston are connected with two downpipes respectively.

When the amount of liquid that needs to be separated is large, the two liquids in the bucket body can flow to the lower tube at the same time by moving the tee of the piston, and it can be completed at one time without changing the container. In the junior high school stage, the main function of the separating funnel is to control the rate of chemical reactions. This device is a kind of experimental vessel with good function in scientific research and chemical experiments.

The separating funnel is divided into various styles such as spherical, pear-shaped and cylindrical, the spherical separating funnel has a longer neck, which is mostly used for the instrument of adding liquid dropwise in the gas making device, and the neck of the pear-shaped separating funnel is relatively short, and it is commonly used as an instrument for extraction operation.

The separating funnel has a piston in the neck, which is an important reason why it is different from ordinary funnel and long neck funnel, because there is no piston in the neck of ordinary funnel and long neck funnel, and it cannot flexibly control the liquid.

The separating funnel is supposed to separate two immiscible liquids. Two immiscible solutions are stratified together, the dense one is below, the density is smaller, the lower liquid can flow out from the small mouth, and after the flow is exhausted, the upper liquid can be poured out from the upper mouth to achieve the purpose of separating.

Before using the separating funnel, remove the stopcock core on the funnel neck and apply petroleum jelly, but not too much, so as not to block the flow hole. Insert the separating funnel into the plug groove and rotate to make the oil film uniform and transparent, and rotate freely. Then close the, fill the funnel with water, check whether the is leaking, and the non-leaking separating funnel can be used.

The amount of liquid added to the funnel should not exceed 3 4 of the volume. And it should not be filled with alkaline liquid. To prevent impurities from falling into the funnel, the plug on the mouth of the funnel should be closed.

When using, hold the funnel ball with the tiger's mouth with your left hand, and turn the piston with your thumb and index finger to control the dosing. At this time, the small groove of the glass plug should be aligned with the small hole on the side of the funnel mouth, so that the liquid can be added smoothly.

The piston controls the flow of liquid as the liquid in the separating funnel flows downward, and to stop the reaction, the piston is tightly closed, so that the drop-off liquid can be stopped immediately. When discharging liquid, the groove on the grinding plug and the small hole in the neck of the funnel should be aligned, so that the air inside and outside the funnel is connected, and the pressure is equal, so that the liquid in the funnel can flow out smoothly. When dispensing, according to the principle of "downflow and upflow", open the piston to let all the liquid in the lower layer flow out, and close the piston.

The upper layer is poured from the upper mouth. The separating funnel should not be heated. Wash the funnel after use.

If the separating funnel has not been used for a long time, wipe the clean, put a paper strip between the plug core and the plug groove, and cover the piston with an elastic band to prevent the scrub from sticking.

I hope I can help you with your doubts.
