Dropping Funnel

Quantity:

Dropping funnel is a kind of cylindrical dropping funnel which is easy to add liquids, and there is no gas leakage when adding liquids, made of borosilicate glass 3.3.The reaction rate can be controlled by controlling the rate of dropping liquids. It can also be installed in a reaction device for dropping feeding liquids. The main body of the funnel is a slender vertical cylindrical glass cylinder. The upper of the funnel body has a mouth of ground-in glass stopper, and the lower is equipped with glass stopcock and funnel pipe. Because the funnel body is a slender cylinder, it is easier to control than the pear shape in separation. It is often used in the operation of synthetic reaction to cooperate with multi-mouth flasks as a filling device. Especially when composing a synthetic stratification device with reflux stirring, the cylindrical dropping funnel is the slender main body and occupies less spherical area because of the small spherical area of multi-mouth flasks, so it is more suitable. It is suitable for slowly adding liquid. The structure ensures that the liquid droplets are added in droplets instead of flowing along the reactor wall. It is convenient to observe the acceleration of the liquid droplets and to place the droplets in the middle of the container. It is convenient to mix the reactants, improve the reaction rate and reduce the side reactions.
