History

3M Separation and Purification Sciences Division has a long and eventful history. Today we evolved as a company dedicated to research, development and production of high quality membranes for medical and technical uses.

3M Separation and Purification Sciences Division, formerly Membrana, has its roots in a textile company developing and producing textile fibres. From those roots it advanced the membrane technology and reached its current position as one of the leading independent membrane manufacturers and leading partner for membrane technology worldwide.
