The Agitated Batch Crystallizer demonstrates the crystallization process from a saturated solution under controlled cooling. It helps students study nucleation, crystal growth, and supersaturation. The unit includes a glass vessel, agitator, cooling coil, and temperature control system for accurate operation. Learners can determine crystallization rate and yield. Suitable for engineering colleges, polytechnics, and ITIs, this durable and safe setup provides hands-on training in industrial crystallization and mass-transfer processes.
