Complete 8/16-Channel Pinch Valves Automated Perfusion System with programmable timers and channel sequences for precise timing during manual operation


Pinch tubing O.D.:

1/8in. (1/16in. optional)

Remote control:



8-channel, can be reduced down to 1-channel


up to 3ft. adjustable, for gravity driven solution flow

Solution cylinders:

60ml x8 syringes


100ft. polyethylene tubing, fits perfusion manifold directly;
50ft. Tygon tubing, fits provided barbed luer connectors for syringes


barbed luer-locks and ferrule-type to connect to solution cylinders and between Tygon & polyethylene tubing

Anti-vibration mounting:

a. 1x1 ft. stand,
b. magnetic stand,
c. M8 threaded surfaces

In the pinch valve a soft tubing is pinched closed by the valve, and opens when the channel is ON. The results are simple tubing replacement and easy system cleanup after experiments. Recommended for strong solvents and reagents, and for hard to wash/clean solutions. Designed for animal physiology and cell research applications. The valves are mounted inside a metal box to shield your system from electrical noise. The system comes with manifold that fits to perfusion chambers for cultured cells/tissue slices, Petri dish and oocytes. Includes soft Tygon, polyethylene tubing and fitting to connect to pinch tubing. Includes 60ml syringes/reservoirs.  Includes easy disconnect luer fitting for tubing and included syringes. Compatible with data acquisition and imaging systems, compatible with LabView, MatLab, pClamp, IPlab, PatchMaster, Metamorh, MetaFluor. Since valves are inside the metal box and are connected to the controller through shielded cables, there is no electrical noise during switching.

The included unique flexible stand provides vibration-free operation and includes both a stand and a small magnetic base. The magnetic base does not take a lot of space from your set-up, but allows to position perfusion solutions near your sample. The post consists of 0.5 in. O.D., 1 foot long aluminum parts and can be extended to 3 feet high. An 1.5 in. flowerette head screw will fix the syringes on the post, making a traditional syringe holder. Comes with 60ml syringes, stop-cocks, and fitting. The holder can be also mounted on threaded M8 surfaces. Sample publications:

Complete 16-Channel Pinch Valves Perfusion System

To form a 16-channel setup, this system includes two sets of the above parts, included with the 8-channel system, which can be operated by the same 16-channel controller.

16-channel valve controller

Both system come with a 16-channel controller. The controller opens valves through
  • manual buttons
  • wireless remote control
  • optically isolated digital or TTL signals generated by a computer or other equipment
  • analog signal
  • RS232 port (or USB connection) for software control
The controller can operate in AUTO Memory mode, to program timers and channels sequences for precise timing during manual operation;

INHIBIT mode with manual and external controls allows you to switch all channels OFF at once, if required. 

The controller has an option for valves control by Binary Encoding using only 2-4 digital inputs, in case if a limited number of digital outputs are available in your system. The RS232 port allows automation of solution switching and integration with data acquisition and imaging systems.

ANALOG output can be configured to monitor channel switching during manual operation.

SET output is used to switch an outflow unit ON automatically every time perfusion is ON.

RS232 port allows software control by any imaging or data acquisition setup. Can be upgraded to USB/RS232 adapter. 

Includes 12V output internal 120/220V power supply.

Specifications (controller):




optically isolated digital signals and TTL, Analog input, RS232 software command

Manual Overdrive:

Manual touch-pad switches, override electronical inputs

Remote control:


Auto Memory:

To program timers and channels sequences for precise timing during manual operation

Code mode:

Use only 4 TTL inputs to encode all channels

Close mode:

Inhibits all outputs to the valves, manual and electronical inputs

Analog and SET outputs:

To switch outflow units CFPS-1U and for telegraph output

Custom modifications:

Additional features can be added or modified on request


5 x 12 x 9 in.


120/240 VAC external power supply
