2. Laboratory glassware - Wikipedia

   en.wikipedia.org/wiki/Laboratory_glassware

   Three beakers, an Erlenmeyer flask, a graduated cylinder and a volumetric flask. Laboratory glassware is a variety of equipment used in scientific work, traditionally made of glass. Glass may be blown, bent, cut, molded, or formed into many sizes and shapes. It is commonly used in chemistry, biology, and analytical laboratories.

3. Beaker (laboratory equipment) - Wikipedia

   en.wikipedia.org/wiki/Beaker_(laboratory_equipment)

   In laboratory equipment, a beaker is generally a cylindrical container with a flat bottom. [1] Most also have a small spout (or "beak") to aid pouring, as shown in the picture. Beakers are available in a wide range of sizes, from one milliliter up to several liters. A beaker is distinguished from a flask by having straight rather than sloping ...

   en.wikipedia.org/wiki/Watch_glass

   A watch glass is a circular concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance, and as a cover for a beaker. When used to cover beakers, the purpose is generally to prevent dust or other particles from entering the beaker; the watch glass does ...

6. Laboratory flask - Wikipedia

   en.wikipedia.org/wiki/Laboratory_flask

   Laboratory flasks have traditionally been made of glass, but can also be made of plastic. At the opening(s) at top of the neck of some glass flasks such as round-bottom flasks , retorts , or sometimes volumetric flasks , there are outer (or female) tapered (conical) ground glass joints .

7. Round-bottom flask - Wikipedia

   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.
