Complete 8-Channel Pinch Valves Perfusion System
Specifications: |
Pinch tubing O.D.: | 1/8in.
(1/16in. optional) |
Manifold: | 8-channel,
can be reduced down to 1-channel |
Height: | up to 3ft. adjustable, for gravity driven solution flow |
Solution cylinders: | 60ml
x8 syringes |
Tubing: | 100ft. polyethylene tubing, fits
perfusion manifold directly;
50ft. Tygon tubing, fits provided barbed luer connectors for
syringes |
Fitting: | barbed luer-locks and ferrule-type to connect to solution cylinders
and between Tygon & polyethylene tubing |
Gas adapter: | saturate solutions with gas mixtures, CO2 and O2
for example
(requires CO2 controller) |
Anti-vibration mounting: | a. 1x1 ft. stand,
b. magnetic stand,
c. M8, M6, or 1/4-20 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. 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 and fitting to connect to pinch tubing. Includes 60ml
syringes/reservoirs. Comes
with tubing, and manifolds. Includes easy disconnect fitting for tubing and included syringes.
Comes with gas adapter to saturate solutions with gas mixtures, CO2 and O2 for example.
Comes 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
Compatible with data acquisition and imaging systems.
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 syringe holder 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 M6,
M8 or 1/4-20 surfaces.

16-channel valve controller
 The included 16-channel controller can operate in
AUTO Memory mode, when a set of
chosen valves opens automatically at the time the other valves
close. This is useful for automatic switching to preset solutions
after the test solution is OFF, and provides uninterrupted solution
flow.
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 imaging
systems.
ANALOG output can be configured to monitor channel switching
during manual operation. By default, ANALOG output is used to switch an
outflow unit ON automatically every time perfusion is ON.
With optional RS232UP upgrade up to 32 channels (two controllers)
can be operated through a single RS232 port. Up to 10 controllers
(RS232UP only) can be connected in a chain to control 320 channels
through the same RS232 (or USB) port.
Comes with an external 120/220V power supply.
