Method for improving nucleation of crystals from solution

Abstract

The present invention is related to a method for nucleating crystals from a solution comprising the steps of: injecting in a first capillary (1) tube an under saturated solution comprising a solvent and a soluble compound to be crystallised; changing the local conditions of the solution downstream of the capillary tube (1) to supersaturated conditions above the metastable conditions, the transition time of the fluid flowing in the capillary tube between the under saturated conditions and the supersaturated conditions above the metastable conditions being less than 1000 ms, preferably below 100 ms, even more preferably less than 10 ms.
