Organic Materials Chemistry - Service and Equipment
We are able to perform custom synthesis and we are prepared to solve even demanding analytical tasks. Table 1 summarizes the experimental techniques available in the department.
Please do not hesitate to contact Prof. Dr. Uwe Beginn or Dr. Sabrina Fischer-Lang and challenge us with your task.
