The laboratory vacuum pump is designed to reduce the pressure inside the system, thereby lowering the boiling point of the solvent. By lowering the boiling point, the solvent evaporates at a much lower temperature, reducing sample degradation.
A cold trap is a device that condenses vapors except permanent gases into a liquid or solid in vacuum applications. Its primary objective is to prevent vapors from entering a vacuum pump and causing contamination.

There are various types of lab vacuum pumps, including oil-free, belt-driven, and diaphragm pumps. Some of the most typical types are Rotary Vane, Rotary Screw, Diaphragm, Piston, and Diffusion.
Lab vacuum pumps are widely used in processes such as filtering, drying, distillation, extraction, chromatography, and more.
Oil-based pumps, such as diffusion and mechanical rotary pumps, are common sources of contamination in vacuum systems due to their use of oil as either a working fluid or lubricant.
To prevent oil vapors from entering the cavity, a cold trap can be placed at the mouth of the pump. This greatly reduces the risk of backstreaming and contamination.
