Perfusion System Control System

VCS Computer-controlled Valve Control System
The Valve Control System lies at the heart of a multi-valve perfusion system designed to automate and control the delivery of solutions to imaging and recording chambers. The flexible design of these systems allows it to be used in diverse applications. The VCS systems are configured to control up to 8 Pinch, PTFE, or Mini valves.

Easy to Operate
Each valve is individually accessed by a manual touch display, the included PC software, an external analog signal, or an external digital signal (TTL). An event marker pulse, generated each time a valve is switched on, is provided for chart recordings. A syncronization pulse can be generated by use of the trigger/sync connector (digital I/O, TTL) to line up valve triggering and recordings for optimum data analysis.

Features
Pinch Valve Systems
Pinch valves are the simplest to maintain as the solution never comes in contact with the valve and tubings are easily changed.
Valves are dual acting (3-way) with both normally open and closed sides. A Y-connector at the valve input permits solution flow to waste with the valve off.

PTFE Valve Systems
PTFE valves are available for applications where resistance to chemicals is a concern. The valves are 2-way (either on or off).
