Guide and selection support
Evaporators are used in chemical and analytical laboratories to purposefully remove solvents through evaporation, thereby concentrating samples. Evaporation simplifies downstream analytical steps and increases detection sensitivity.
When choosing an evaporator, several criteria are important, including the evaporation method, compatibility with the solvents, and the sample volumes involved. Ease of use and maintenance requirements are also key factors.
LabFinder provides a structured overview of evaporators, offering information on applications, types, and selection criteria. This supports users in selecting suitable equipment for their laboratory needs.
Applications and Benefits
Evaporators are used in laboratories to reduce the volume of liquid samples by evaporating the solvent. They are mainly employed to concentrate solutions, increasing the analyte concentration and simplifying sample preparation. Evaporators are found in chemical laboratories, analytical chemistry, and sample preparation for various measurement methods.
Selection Criteria
Multiple factors are important when selecting an evaporator: What volume and type of solvents will be processed? Which evaporation method best suits the sample material and lab capacity? Other considerations include user-friendliness, safety when handling volatile or flammable solvents, and maintenance requirements.
Variants and Measurement Principles
There are different types of evaporators, such as rotary evaporators, which use rotation and heating to achieve efficient evaporation, and vacuum evaporators, which operate under reduced pressure to enable evaporation at lower temperatures. Ultrasonic evaporators use sound waves to support the evaporation process. The selection depends on the sample properties and required evaporation parameters.
Calibration and Maintenance
Regular cleaning and inspection of components are necessary for reliable operation. Depending on the device, vacuum tightness or the functionality of heating elements may require checking. Maintenance intervals are based on manufacturer specifications and intensity of use.
Limitations of Use
Evaporators are not suitable for all solvents or sample types; for example, substances that are highly sensitive to temperature may be affected. Some devices are unsuitable for large volumes or require additional explosion protection when handling flammable vapors.

Frequently asked questions
How does an evaporator work in the laboratory?
An evaporator removes the solvent from a sample through heat or vacuum, reducing the volume and increasing the concentration of the dissolved substance.
What types of evaporators are available?
Common types include rotary evaporators for gentle evaporation via rotation, vacuum evaporators for evaporation at low temperatures, and ultrasonic evaporators to further support the process.
What should I consider when selecting an evaporator?
Important criteria include the type and amount of sample, the solvent used, desired evaporation speed, ease of use, and maintenance requirements.
What are the limitations when using evaporators?
Evaporators are not suitable for all solvents or temperature-sensitive samples. Large volumes or flammable vapors may require special equipment or additional safety precautions.
How should an evaporator be maintained?
Regular cleaning, checking seals, and, if necessary, function checks of heating elements or vacuum pumps are required to ensure operational safety.
