Evaporators in laboratories are used to separate a solid or liquid solute from a prepared sample for analysis.
This separation is achieved by converting the solvent in the sample into a vapor.
Laboratory evaporators use various techniques such as heat, motion, gas, reduced pressure, or a combination of these methods to accelerate the evaporation process.
Evaporators are commonly used in various fields such as pharmaceutical, environmental, food/beverage, academic, and medical industries.
They are used to concentrate a previously dilute solution by removing solvent, or to completely eliminate solvent and generate a powder suitable for long-term storage.
The widely used rotary evaporator is a common type of laboratory evaporator.
It utilizes motorized systems to rotate a sample flask and manipulate it to and from a heated liquid bath.
A vacuum system and vapor duct are used to divert solvent vapors into a collection flask.
The reduced internal pressure created by the vacuum lowers the solvent's boiling point, allowing it to be distilled out at low temperatures while preserving the chemical structure of the solute or analyte.
The use of evaporators in the laboratory offers several benefits.
It reduces residence and boiling point time, allowing for faster processing of samples, especially those that are heat-sensitive.
Evaporators can be used in various processes such as powder drying, crystallization, and granulation of substances.
They are particularly useful in small-scale labs, pharmaceutical biotechnological industries, and chemical laboratories that require intensive research and handling of industrial samples.
The working principle of an evaporator involves combining a condenser, distillation flask, collecting vessel, and a heating bath.
The samples are placed in the collecting container, which is connected to the distillation flask and condenser.
The samples are then heated over the heating bath.
Some evaporators may also include chillers for cooling purposes.
The evaporator system allows for efficient solvent removal and concentration of samples.
Overall, evaporators are essential in laboratory processes such as distillation, concentration, drying of products, recrystallization, extractions, freeze-drying sample preparation, cannabis applications, and gin applications.
They are crucial instruments in research and chemical laboratories, offering efficient solvent removal and distillation capabilities.
Rotary evaporators, in particular, are preferred over standard distillation systems due to their high distillation efficiency.
