Heating mode of rotary evaporator.

Jul. 08. 2022

Instead of directly heating the reaction solvent, the rotary evaporator transfers heat through the bath pot, making the heating more uniform and the temperature easier to control. Water, oil and sand are commonly used as the heating medium.

How to maintain the magnetic stirring device?

Jul. 07. 2022

Thermostatic water bath is also called magnetic stirring reaction bath because its bottom is equipped with a magnetic stirring device.

How to choose a vacuum pump?

Jul. 06. 2022

Circulating water vacuum pump is widely used in evaporation, distillation, crystallization, filtration, decompression, sublimation and other operations.

What are the reasons for the failure of the stepping motor of the rotary evaporator?

Jul. 05. 2022

The rotary evaporator can make the experimental materials rotate under constant temperature and negative pressure to form a high-temperature film, then evaporate quickly, and then cool the recovered solvent. It is an ideal instrument for distillation and extraction, material crystallization and solvent separation in the laboratory.
