    200 mL Evaporating Dish Home Science Tools
    An analysis of an evaporating dish involves its use in separating a liquid from a dissolved solid via evaporation to produce a concentrated solution or a solid residue . This is achieved by heating the dish to drive off the solvent, which can be done over a flame or in an oven. The dish's shallow, open design with a large surface area promotes quick evaporation, and its spout aids in pouring out the liquid.
    Key features for analysis
    • Design: Shallow, wide, and open, with a pouring spout. This maximizes the surface area for evaporation and allows for easy transfer of liquids.
    • Materials: Commonly made of porcelain or borosilicate glass, which can withstand high temperatures needed for heating over a Bunsen burner. Other materials like glassy carbon, PTFE, and platinum are also used for specific applications.
    • Porcelain: Offers high thermal resistance but can be more delicate than glass.
    • Borosilicate glass: Known for its thermal shock resistance and chemical durability.
    Analytical uses
    • Evaporation of solvents: To concentrate a solution, leaving behind a solid.
    • Drying precipitates: To remove the liquid from a solid precipitate.
    • Drying samples for constant weight: To dry a sample in an oven until it reaches a constant weight for accurate measurement.
    • Ashing of samples: To burn off organic material in a sample to analyze the remaining inorganic residue.
    • Water quality testing: Used to determine the total solids in a water sample by evaporating the water and weighing the residue.

    What does an evaporating dish measure?
    Although evaporation dishes are not frequently used as measuring tools, they can be. Before a sample is evaporated, the dish is weighed. Once evaporation has happened, the dish is weighed again, and the weight of the evaporated substance can be calculated.

    Evaporating Dishes – Sun LabTek
    An evaporating dish is a laboratory tool used to evaporate solvents from a solution, which leaves behind a more concentrated solution or a solid residue . Its wide, shallow shape maximizes the surface area for evaporation. They are commonly made of porcelain or glass and are used for processes like concentrating solutions and separating dissolved substances from a solvent.
    Primary functions
    • Evaporating solvents:
      The most common use is to heat a liquid to evaporate the solvent (like water), leaving behind the non-volatile solute.
    • Concentrating solutions:
      By removing the solvent, the remaining solution becomes more concentrated.
    • Producing solids:
      This process can be carried out until the solvent is completely gone, leaving a solid precipitate in the dish.
    • Crystallization:
      Evaporating dishes can be used to facilitate the formation of crystals as a concentrated solution cools.
    • Laboratory testing:
      They are used in various tests that require heating a sample to dryness, and their high temperature resistance makes them suitable for creating a stable reaction environment.
    Key features
    • Wide shape: A large surface area allows for faster evaporation.
    • Spout: Many evaporating dishes have a spout to allow vapors to escape and prevent pressure buildup.
    • Material: They are made of durable materials like porcelain or borosilicate glass that can withstand high temperatures and chemical corrosion.

    How to use an evaporating dish in the laboratory?
    To use an evaporating dish, first ensure that it is clean and free of any extraneous matter. The substance that you want to evaporate should be placed inside the dish, either directly or by using a small amount of solvent to dissolve it first. Next, carefully heat the dish using a Bunsen burner or other heat source. 2023年11月3日
