Crystallization and Solubility Information Leaflet
To support isolation of large quantities of material, we utilise a Technobis Crystal16 crystallizer to determine solubility profiles of materials of interest. With as little as 100 mg of sample solubility curves can be generated. We have used this to great effect to successfully eliminate silica gel chromatography from key reaction steps and for upgrading materials to higher specifications.
First Pass Solubility Screen
- Range of common organic solvents and water
- Class 2 and Class 3 options

Example Solubility Curve and Metastable Zone
Requirements
- For solubility curve generation: 100 – 500 mg sample
- More if intrinsic solubility is high
