VCS Computer-controlled Valve Control System

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.

Valve Control Systems

• Up to 8 channels
• Choice of 3 valve types: pinch, PTFE, or Lee miniature valves
• Low noise operation
• Low self-heating design

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. An optional (but included) 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).

Mini-Valve Systems

The mini valve systems are available in standard size tubes, and with large tubes to support higher flow rates. The standard sized tube model is the most commonly used and is what's supplied with our VCS-77 systems. This is also the preferred tube size for applications using our SF-77C Fast Stepper.

We also have a large tube (LT) mini valve available which is identical to the standard mini valve except the valve input and output tubes have larger ID to permit flow rates up to 10 ml/min.

In all cases, these 3-way valves can be configured as strict on/off or as continuous flow to waste if desired. The mini valve systems are ideally suited for use with the SF-77C perfusion stepper systems.

Controller and Software

Touch and PC Software controlled

Software The system can be operated either manually via touch display or via provided PC software. Software and updates are free. An SDK ia available for integrating into your own software. The current VCS software can be downloaded here.
7 “ Touch Display Comfortable handling directly at the device Allows for standalone operation by saving protocols directly on valve controller Change between manual, digital in, analog in and programmatic operation mode
Valve Stands Software controllable for easy phase control Available in all corresponding system sizes Custom design for pinch, PTFE, or mini valves
Connector Options Digital I/O Analog in Trig/Sync (for TTL and BNC) Valve connector USB 3.0 (for PC software control)

System Choices

The VCS-6 or VCS-8 Perfusion Valve Control Systems are available with either standard pinch valves or with PTFE valves. These systems include a VCS controller, an eight channel valve bracket with pinch or PTFE valves and 8 ft long cable, reservoir holder with eight 60cc reservoirs, support stand, stopcocks, tubing Connectors, and an MP Series Manifold. The systems with pinch valves are also supplied with Tygon Tubing (1/32 in x 50 ft, ID x L) and C-Flex" Valve Tubing for the valves. The systems with PTFE valves include PTFE tubing (1/16 in x 25 ft, ID x L). Both systems come with 10 ft of PE-90 tubing.

The VCS-6M or VCS-8M Mini Valve Perfusion Control System is available with the VCS Controller, an eight channel valve bracket with Lee mini valves and 8 ft long cable, reservoir holder with eight 10cc reservoirs, support stand, stopcocks, tubing connectors, an ML series manifold, and two packages of PE-50 tubing (50 ft long).
