The parameters and configuration within this manual should not be changed without
consultation with a Repligen representative. The controller, when properly maintained and
serviced, should be able to handle almost all cell culture conditions and viscosities.
Should you determine that the controller is not functioning correctly and exchanging the full
volume of the diaphragm pump with each stroke, please immediately contact Repligen for
further assistance.
