(B) A tall-form or Berzelius beaker (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.
An example is Heller's test where a test tube containing proteins has strong acids added to it. A cloudy ring forms where the substances meet, indicating the acids are denaturing the proteins. The cloud is a sign that proteins are present in a liquid.
Laboratory drying rack can contain and dry up various types of laboratory glassware such as beaker, Erlenmeyer flask, volumetric flask, and graduated cylinder. Laboratory drying rack is usually used to dry up the tube in the laboratory; for example, it can help in drying test tube , boiling tube , and Thiele tube .
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.
A shaker is a piece of laboratory equipment used to mix, blend, or agitate substances in a tube or flask by shaking them. It is mainly used in the fields of chemistry and biology . A shaker contains an oscillating board that is used to place the flasks, beakers , or test tubes.
The aqueous phase is being drained into the beaker. A separatory funnel , also known as a separation funnel , separating funnel , or colloquially sep funnel , is a piece of laboratory glassware used in liquid-liquid extractions to separate ( partition ) the components of a mixture into two immiscible solvent phases of different densities .

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.
Flat-bottomed flask: A flask with similar uses as the round-bottom flask, but with a flat bottom that allows it to stand on a level surface.; Florence flask: A flask similar to the flat-bottomed flask that has round bodies and either a round bottom or a flat bottom so that one can stand the flask on a level surface.
