Manual or computer controlled 
Low noise 
Low self heating design

Warner perfusion valve control systems are uncomplicated and easy to operate. The VC-8 Valve Controller is configured to control up to 8 valves. Each valve is individually accessed by a manual switch, an external analog signal, or an external TTL signal. A spill sensor probe is included for detecting an overflow condition in your perfusion chambers and will shut off all valves thereby protecting your valuable microscope optics. An event-marker pulse, generated each time a valve is switched on, is provided for output to tape or chart recorders. Systems include all components necessary to get set up and running in very little time. The VC-8P Pinch valve and VC-8T PTFE valve systems include the VC-8 controller, 8 valves, a valve bracket with 8 ft. cable and MP-8 Series manifold. 

Pinch valve systems are supplied with C-flex valve tubing. Included with the Pinch and PTFE Valve Systems are eight 60 cc reservoirs, a reservoir holder and support stand, stopcocks and tubing connectors. Pinch valve systems are also supplied with 50 ft. of Tygon tubing. Systems with a PTFE valve include 25 ft. of PTFE tubing. The VC-8M Mini-Valve Perfusion Control System includes the VC-8 Controller, 8 valves, and a valve manifold with 8 ft. cable and an ML-8 Series manifold. Also included are eight 10 cc reservoirs, a reservoir holder, ring stand, stopcocks, tubing connectors and 100 ft. of PE-50 tubing. 


VC-8P 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. Y connectors at the valve inputs permit solution flow to waste with the valves off. 

VC-8T 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). 

VC-8M Mini-Valve Systems 

The VC-8M is designed for slow flow perfusion systems where smaller diameter tubing is used. Eight valves mount directly to a compact Delrin manifold. The 3-way valves allow for solutions to flow to waste if desired. The VC-8M system is ideally suited for use with the SF-77B Fast-Step Perfusion Stepper Systems. The VC-8MLT features larger ports to accommodate PE-160 tubing used on most Warner chambers, this version will permit flow rates of 10ml/min
