2. Dropping funnel - Wikipedia

   en.wikipedia.org/wiki/Dropping_funnel

   A dropping funnel or addition funnel is a type of laboratory glassware used to transfer liquids. They are fitted with a stopcock which allows the flow to be controlled. Dropping funnels are useful for adding reagents slowly, i.e. drop-wise. This is desirable when the quick addition of the reagent results in side reactions, or if the reaction is ...

   en.wikipedia.org/wiki/Büchner_funnel

   A Büchner funnel is a piece of laboratory equipment used in filtration. [1] It is traditionally made of porcelain , but glass and plastic funnels are also available. On top of the funnel-shaped part there is a cylinder with a fritted glass disc/perforated plate separating it from the funnel.

   If it is desired to retain the bottom layer in the separating funnel for further extractions, both layers are taken out separately, and then the former bottom layer is returned to the separating funnel. Each independent solution can then be extracted again with additional batches of solvent, used for other physical or chemical processes.

   en.wikipedia.org/wiki/Round-bottom_flask

   Round-bottom flasks (also called round-bottomed flasks or RB flasks) are types of flasks having spherical bottoms used as laboratory glassware, mostly for chemical or biochemical work. [1] They are typically made of glass for chemical inertness ; and in modern days, they are usually made of heat-resistant borosilicate glass.

   en.wikipedia.org/wiki/Laboratory_flask

   They are usually a cone shape—similar to the shape of an Erlenmeyer flask, but also have side neck, usually affixed to the side, 2 / 3 up from the bottom. The flasks are used to cooperate with vacuum aspirator or vacuum pumps in the vacuum filtration, or as additional security during the distillation and other processes carried out under ...

   Faraday published Chemical Manipulation in 1827 which detailed the process for creating many types of small tube glassware and some experimental techniques for tube chemistry. [3] [4] Berzelius wrote a similar textbook titled Chemical Operations and Apparatus which provided a variety of chemical glassblowing techniques. [3]
