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. [2] Erlenmeyer flasks have wide bases and narrow ...
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.
Volumetric flask is used for preparing liquids with volumes of high precision. It is a flask with an approximately pear-shaped body and a long neck with a circumferential fill line. Dewar flask is a double-walled flask having a near-vacuum between the two walls. These come in a variety of shapes and sizes; some are large and tube-like, others ...
The word Erlenmeyer may mean: Richard August Carl Emil Erlenmeyer (1825–1909), German chemist; Erlenmeyer flask, conical glassware invented by Richard Erlenmeyer; The bony deformity named Deformity type Erlenmeyer flask because of the similarity to the shape of the flask; Friedrich Gustav Carl Emil Erlenmeyer (1864–1921), son of R.

Cross section of a Büchner Flask. Note the hose barb pointing right for attaching a vacuum source. A Büchner flask, also known as a vacuum flask, [1] filter flask, suction flask, side-arm flask, or Bunsen flask, is a thick-walled Erlenmeyer flask with a short glass tube and hose barb protruding about an inch from its neck.
Watch glasses are also sometimes used to cover a glass of whisky, to concentrate the aromas in the glass, and to prevent spills when the whisky is swirled. [1] Watch glasses are named so because they are similar to the glass used for the front of old-fashioned pocket watches. These large watch glasses are occasionally known as clock glasses.
(C) A flat beaker or crystallizer Philips beaker which can be swirled like a conical flask. Standard or "low-form" (A) beakers typically have a height about 1.4 times the diameter. [3] The common low form with a spout was devised by John Joseph Griffin and is therefore sometimes called a Griffin beaker.
