(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.
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.

Beaker (glassware) Many of these flasks can be wrapped in a protective outer layer of glass, leaving a gap between the inner and outer walls. These are called jacketed flasks; they are often used in a reaction using a cooling fluid.
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.
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.
A watch glass is a circular concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance, and as a cover for a beaker. When used to cover beakers, the purpose is generally to prevent dust or other particles from entering the beaker; the watch glass does ...
A 100 ml volumetric flask with stopper 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.
