2. Beaker (laboratory equipment) - Wikipedia

   en.wikipedia.org/wiki/Beaker_(laboratory_equipment)

   (A) A low-form or Griffin form beaker (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 ...

3. Laboratory glassware - Wikipedia

   en.wikipedia.org/wiki/Laboratory_glassware

   Glass evaporating dishes, such as watch glasses, are primarily used as an evaporating surface (though they may be used to cover a beaker.) The Petri dish is a flat dish filled with a nutritious gelatin that allows for microorganisms to quickly grow, its named after its inventor Julius Petri in the 1880s.

4. Separatory funnel - Wikipedia

   en.wikipedia.org/wiki/Separatory_funnel

   All of these solvents form a clear delineation between the two liquids. [2] The more dense liquid, typically the aqueous phase unless the organic phase is halogenated , sinks to the bottom of the funnel and can be drained out through a valve away from the less dense liquid, which remains in the separatory funnel.

5. Evaporating dish - Wikipedia

   en.wikipedia.org/wiki/Evaporating_dish

   If heated in a flask or beaker, a part of the evaporated liquid condenses on the vessel walls and flows back into the solution. This does not happen in a dish. When heating liquid in an evaporating dish, the low walls encourage splashes and so stirring or swirling of evaporating liquids is considered bad practice, owing to the risk of spillage.

6. Watch glass - Wikipedia

   en.wikipedia.org/wiki/Watch_glass

   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 ...

7. Glass rod - Wikipedia

   en.wikipedia.org/wiki/Glass_rod

   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
