This paper introduced a new-fashioned recrystallization apparatus and the application in semi-micro solid organic compound recrystallization experiment. The operation method was illustrated by the example of N-acetyl anilide recrystallization. This apparatus has advantages for saving the area of experiment table, easy installation and dismantlement, easy operation , higher rate of product recovery, short experiment time. It is of great applied value to semi-microorganic experiment.
