  2. Laboratory flask - Wikipedia

    en.wikipedia.org/wiki/Laboratory_flask

    Laboratory flasks are vessels or containers that fall into the category of laboratory equipment known as glassware. In laboratory and other scientific settings, they are usually referred to simply as flasks. Flasks come in a number of shapes and a wide range of sizes, but a common distinguishing aspect in their shapes is a wider vessel "body ...

  3. Conical measure - Wikipedia

    en.wikipedia.org/wiki/Conical_measure

    Conical measure. A conical measure is a type of laboratory glassware which consists of a conical cup with a notch on the top to allow for the easy pouring of liquids, and graduated markings on the side to allow easy and accurate measurement of volumes of liquid. They may be made of plastic, glass, or borosilicate glass.

  4. Volumetric flask - Wikipedia

    en.wikipedia.org/wiki/Volumetric_flask

    Volumetric flasks of various sizes. 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 ...

  5. Volume - Wikipedia

    en.wikipedia.org/wiki/Volume

    Containers can only hold a specific amount of physical volume, not weight (excluding practical concerns). For example, a 50,000 bbl (7,900,000 L) tank that can just hold 7,200 t (15,900,000 lb) of fuel oil will not be able to contain the same 7,200 t (15,900,000 lb) of naphtha , due to naphtha's lower density and thus larger volume.

    en.wikipedia.org/wiki/Erlenmeyer_flask

    Erlenmeyer flask. An Erlenmeyer flask, also known as a conical flask (British English) [1] or a titration flask, is a type of laboratory flask with a flat bottom, a conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer (1825–1909), who invented it in 1860.

  7. Beaker (laboratory equipment) - Wikipedia

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

    Laboratory flask. 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 ...

  8. Round-bottom flask - Wikipedia

    en.wikipedia.org/wiki/Round-bottom_flask

    Both distilling (2, left) and receiving (8, right) flasks are round-bottom flasks. 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 ...

  9. Cone - Wikipedia

    en.wikipedia.org/wiki/Cone

    3D model of a cone. A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex. A cone is formed by a set of line segments, half-lines, or lines connecting a common point, the apex, to all of the points on a base that is in a plane that ...
