In this work, crystallization experiments were carried out on four separate aqueous solutions of adipic acid, ammonium sulfate, urea and L-glutamic acid to measure the growth rate of these crystals under varying values of temperature, stirrer speed, cooling rate and holding time. All experiments were carried out in the Mettler Toledo LabMax, which is an automated laboratory reactor. A polarized light microscope was used to capture the images of the crystals and Image Pro Plus software was used for the analysis of crystal samples. Due to technical difficulties, the data could not be measured for adipic acid, ammonium sulfate or urea. L-Glutamic acid was much easier to work with and it was possible to obtain data. The growth rate for the b form of L-glutamic acid was estimated from the experimental data using a numerical simulation
