Uses of Evaporating dish
- Evaporation:
The primary use of an evaporating dish is to evaporate liquids. It allows for the gradual evaporation of a solvent from a solution, concentrating the remaining solute.
- Heating Solutions:
Evaporating dishes can be heated directly over a flame or on a hot plate. This is useful for boiling solutions or driving off solvents.
- Crystallization:
They can be used in crystallization processes where a solution is evaporated to obtain crystals of a solute.
- Drying Samples:
Evaporating dishes are often used to dry solid samples by allowing moisture to evaporate at room temperature or with gentle heating.
- Sample Preparation:
In analytical chemistry, they may be used to prepare samples for further analysis, such as drying or concentrating a solution before spectroscopic or chromatographic analysis.
- Weighing Solids:
Some labs use evaporating dishes to weigh solid residues after evaporation, providing a convenient container for precise measurements.
- Reactions:
They can be used to conduct small-scale reactions that require heating or evaporation of solvents.
