Air Drive, Electrical Drive technology

Drive technologies are available as electric motor or air drive. Air drive technology is the industry standard and provides a truly proportional control of speed and acceleration for reliability and long life operation.

The ‘e-drive’ combines the ultracentrifugation technology of the Alfa Wassermann KII with up to date electric drive technology, to create an Ultracentrifuge which is reliable, compact and low cost to run for Bio-pharmaceutical R&D and for cGMP manufacturing.
