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.
Erlenmeyer flasks (introduced in 1861 by German chemist Emil Erlenmeyer (1825–1909)) are shaped like a cone, usually completed by the ground joint; the conical flasks are very popular because of their low price (they are easy to manufacture) and portability; Volumetric flask is used for preparing liquids with volumes of high precision. It is ...
A Fleaker is a brand of container for liquids used in the laboratory. It can be described as a cross between the Griffin beaker and the Erlenmeyer flask. [1]Like a beaker, the bottom is flat, with the sides meeting the bottom at a 90-degree angle.
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.
Two funnels: A - Cone, or Pear-shaped, B - cylindrical. A separating funnel takes the shape of a cone with a hemispherical end. It has a stopper at the top and stopcock (tap), at the bottom.
These are used in filtration under low pressure with a Buchner flask. [2] Hot filtration funnel is a less commonly seen funnel where the funnel is jacketed, and surrounded by a heated fluid. [3] Eco funnel is equipped with a latching lid and gasket to reduce chemical contamination and conform to OSHA and EPA regulations. [4]
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. A. C. E ...
