The AZURA Prep. 100/250 gradient system is designed for complex purifications of small molecules in pilot scale. It is designed and optimized for all Prep.-LC applications in RP/NP mode, ion exchange, hydrophobic interaction and size exclusion chromatography. All system modules can be freely exchanged, and further modules can be added optionally, to give more flexibility.
