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 ...

   Older clear-glass Pyrex manufactured by Corning, Arc International's Pyrex products, and Pyrex laboratory glassware are made of borosilicate glass. According to the National Institute of Standards and Technology , borosilicate Pyrex is composed of (as percentage of weight): 4.0% boron , 54.0% oxygen , 2.8% sodium , 1.1% aluminum , 37.7% silicon ...

6. Evaporating dish - Wikipedia

   en.wikipedia.org/wiki/Evaporating_dish

   An evaporating dish is a piece of laboratory glassware used for the evaporation of solutions and supernatant liquids, [a] and sometimes to their melting point.Evaporating dishes are used to evaporate excess solvents – most commonly water – to produce a concentrated solution or a solid precipitate of the dissolved substance.

7. 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 .

8. Volumetric flask - Wikipedia

   en.wikipedia.org/wiki/Volumetric_flask

   A volumetric flask (measuring flask or graduated flask) is a piece of laboratory apparatus, a type of laboratory flask, calibrated to contain a precise volume at a certain temperature. Volumetric flasks are used for precise dilutions and preparation of standard solutions. These flasks are usually pear-shaped, with a flat bottom, and made of ...

9. 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.
