(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.
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.
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.
Method of swirling an Erlenmeyer flask during titration. The slanted sides and narrow neck of this flask allow the contents of the flask to be mixed by swirling, without risk of spillage, making them suitable for titrations by placing it under the buret and adding solvent and the indicator in the Erlenmeyer flask.

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.
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 . [ 1 ]
This process is also used to pour a large-mouthed flask or beaker into a test tube. [4] Glass rods can also be used to induce crystallization in a recrystallization procedure, when they are used to scratch the inside surface of a test tube or beaker. They can also break up an emulsion during an extraction. [5] Stir rod in beaker
Hirsch funnels are shaped much like normal funnels, but contain holes or sintered glass at the base for quick filtrations. Dropping funnels are a cylindrical, regularly graduated funnel with standard taper ground glass joints. These are often supplied with a pressure equalizer.
