The VSO®-EV is a Miniature Electronic Vacuum Controller specifically configured and optimized for precise vacuum control. The VSO®-EV converts a variable electrical control signal into a closed-loop, tightly regulated pneumatic output. Often used for aspirating liquid samples for pipette dispensers, the VSO®-EV offers closed loop control around critical system parameters through the use of an internal vacuum sensor. The VSO®-EV is well suited for high precision automated laboratory instruments, meeting the most stringent separation and detection requirements.
