Porcelain Evaporating Dishes
Porcelain evaporating dishes are ceramic containers used to evaporate liquids, commonly in laboratory or chemical experiments.
The porcelain is uniform in thickness and dense which allows stable mechanical strength and little permeability. Large mouth and shallow bottom, fast evaporation. Strong wear resistance, easy to grind; the outer surface is smooth, easy to grasp and clean. The round mouth has a pointed mouth, and the liquid is easily poured out.

Features of Evaporating Dish
Material
Evaporating dishes are made of ceramic materials, can withstand higher temperatures, and are often used when dealing with reactive chemicals.
Shape and Size
They come in various sizes, but they usually have a shallow, flat-bottomed design with a spout for easy pouring. The choice of size depends on the volume of liquid you need to evaporate.
Heat Resistance
Evaporating dishes are designed to withstand heating over an open flame or on a hot plate, making them suitable for the evaporation process.
Advantages of Evaporating Dish
Chemical Resistance
These dishes are generally resistant to a wide range of chemicals, making them suitable for working with corrosive substances, acids, and bases.
Easy to Clean
Evaporating dishes are easy to clean and maintain, as they are typically non-reactive and can withstand repeated use without deteriorating.
Uniform Heating
Their flat, shallow design allows for uniform heating of the contents, ensuring consistent evaporation or crystallization.
Containment
Evaporating dishes have a flat bottom and raised walls, which help contain the liquid being evaporated, reducing the risk of spillage.
Common uses
Evaporation
Heating a solution to drive off a solvent, often using a Bunsen burner.
Crystallization
Encouraging the formation of crystals by gradually evaporating a solvent.
Drying samples
Gently heating samples to remove moisture for analysis.
Reagent preparation
Concentrating solutions to a higher molarity by evaporating excess water.
Material
Evaporating dishes are typically made from materials like:
Porcelain
01
Borosilicate glass
02
Quartz
03
PTFE (Polytetrafluoroethylene)
04
Size and Capacity
The size of evaporating dishes can range from small (few milliliters) to large (several hundred milliliters). The choice depends on the volume of the substance to be evaporated and the concentration desired. Larger capacity evaporating dishes require larger heat sources to fully evaporate the liquids inside.
Shape
Typically evaporating dishes are shallow with a flat or rounded bottom. The wide mouth and shallow depth increase the surface area, promoting faster evaporation. The large exposed surface area provides more opportunities for evaporation to occur as molecules break free from the liquid in the dish.
Heat Resistance
The maximum temperature that the dish can withstand without deforming or breaking is the heat resistance specification. This varies based on the material, with porcelain and quartz dishes typically withstanding higher temperatures than glass.
Chemical Resistance
Resistance to chemicals, particularly acids, bases, and solvents can be a very important specification for some evaporating dishes. This is crucial when evaporating corrosive substances.
Thermal Shock Resistance
Evaporating dishes can see rapid changes in temperature. The ability to withstand rapid temperature changes without cracking is typically referred to as thermal shock resistance. Borosilicate glass and quartz have high thermal shock resistance.
Applications of Evaporating Dish
Evaporation
As the name suggests, one of the primary applications of evaporating dishes is the evaporation of solvents from a solution. This is commonly used in chemical and biological laboratories to concentrate solutions or recover valuable substances.
Crystallization
Evaporating dishes are often used in the process of crystallization, where a solute is dissolved in a solvent and then the solvent is gradually evaporated to encourage the formation of crystals.
Precipitation
They can be used to carry out precipitation reactions by mixing two solutions that react to form a solid precipitate. The resulting mixture can then be heated to evaporate excess solvent, leaving behind the solid precipitate for further analysis.
Sample Drying
Evaporating dishes are used to dry samples by heating them gently. This is common in analytical chemistry and material science for preparing samples for various tests and analyses.
Weighing and Weighing Transfer
Evaporating dishes are often used for weighing solid samples or transferring substances to other containers for further analysis, as they can be accurately weighed on a balance.
Reagent Preparation
They can be used for the preparation of concentrated reagent solutions, where a solution is heated to evaporate excess water, leaving behind a more concentrated solution.
Residue Collection
In environmental testing and analysis, evaporating dishes can be used to collect residues from water or soil samples after evaporation, making it easier to analyze the concentrated residues.
Sample Digestion
In analytical chemistry, evaporating dishes can be used to digest samples by heating them with concentrated acids or other reagents to break down complex matrices for subsequent analysis.
