[0002] In chemical synthesis research, the preparation of new compounds is accompanied by the generation of impurities, and scientists need an effective method to purify the synthesized target compounds in order to accurately characterize their structure and test their performance. Recrystallization is a common purification method. For organic synthesis chemists, improvements in recrystallization equipment can help them better study the properties of organic compounds. When studying optically active organic compounds, purifying the compounds through high-quality recrystallization equipment can more accurately measure their optical properties.
