Seeding Studies For Crystallization - Improve Batch Consistency

To Control Crystal Size. Seeding is one of the most straightforward methods used to control supersaturation. During seeding, a small mass of crystals is added to a supersaturation in order to: Start the crystallization at the desired supersaturation level. Provide sufficient surface area to ensure supersaturation is consumed in a controlled way.
