Deliver as little as 100 microliters of precious drugs
   Switch between eight solutions in milliseconds from a single tip.

Minimize cross-contamination with BackStop™ back-flow prevention
  Special 3-way relief valve design stops liquid flow quickly.

Valves and pressure controls in a small box near microscope - no
   stand necessary.

Includes pressurized large-volume reservoir for buffer.

Programmable dispensing, microinjection, perfusion or spritzing of reproducible microliter volumes. Up to eight solutions are stored in 2.5ml cryo tube reservoirs with easy syringe refill ports. Included pneumatic solenoid valves deliver regulated air pressure to push liquids out of the SmartSquirt Perfusion Pencil tip. An AutoMate Scientific (or other) valve controller offers programmable, manual or computer-controlled valve selection for switching which reagent is delivered from the tip. Pulse a valve quickly for microliter delivery, or leave it on longer for constant perfusion. The short delivery path saves expensive reagents. Integrated BackStop check valves prevent backflow found in competing micro-perfusion systems, while special three-way valve design stops liquids quickly. The 0-10psi regulator and air filter require a compressed air or other gas source -- bottle, compressor or lab air. Compare to an eight-channel, 10psi Picospritzer™ at a fraction of the price.
