Perfusion Systems
AutoMate Scientic builds ValveLink8.2 and ValveBank perfusion systems
with several choices of valves (below) in 4, 8, or 16 channels. Systems
include reservoirs, drippers, stopcocks, brackets, ow regulator, ringstand,
tubing and micro-manifold. Please visit http://www.autom8.com/build_
your_own.html to congure a custom system to your specications and

Valves
Solenoid valves are available as part of perfusion systems or sold
separately. We sell 12V DC PTFE and Pinch valves with indicator LEDs
built-in. PTFE valves are faster (open and close in 10 ms.), but pinch valves
are cheaper and easier to clean (open and close in 30-50 ms). PTFE valves
include three choices of
ttings: hose barb (standard),
luer lock, or nut & ferrules for
connecting hard PTFE tubing.
Luer lock ttings allow
direct connection of syringes
as shown. This method
eliminates wasted solution in
tubing between the reservoirs
and valves. Small 2-way
stopcocks are included
with all AutoMate Scientic
perfusion systems. Luer lock PTFE valves
ValveLink8.2 Accessories
BNC cables and rack-mounting brackets make it easier
to connect your ValveLink8.2 to your digital outputs
and to mount the controller in a 19" rack with your
other equipment.

AutoMate Scientic also sells
a full range of manual and
motorized micro-manipulators,
ampliers, stimulus isolators,
data acquisition systems, lter
wheels and pipette pullers.
ValveLink8.2 Laboratory Applications
Perfusion
A ValveLink8.2 can be programmed to precisely switch solutions perfusing
over biological samples for physiological research. The ValveLink8.2’s
circuitry is designed to open valves with low noise for electrophysiological
amplication. Several features called ‘Modes’ have been built into the
ValveLink8.2 for advanced perfusion use.
Washing
Combined with an AutoMate Scientic ported washing tray, the
ValveLink8.2 can automate washing of electrophoresis gels and blots, and
developing of x-ray or photographic lm or prints. You have complete
control over which washing steps of your Western, Northern, Southern,
Coomassie Blue and Silver staining runs are automated and which
are handled conventionally. Unattended washing can save a busy lab
countless hours of tedious monitoring.
Liquid Chromatography
A ValveLink8.2 can be easily programmed to automate solution selection
in multi-step ion exchange, gel ltration or anity chromatography runs
with excellent reproducibility. The ValveLink8.2 is especially useful in
preparative work when a protocol has been established and programmed
to repetitively isolate your valuable molecule.
