The Picospritzer III is a self-contained rack mountable system which supplies repeatable pressure pulses. It was designed for rapid and reproducible ejections of picoliter to nanoliter volumes as used in intracellular or extracellular studies. Volumes dispensed are linear with time and pressure. A pulse duration can be recorded with a special time marker whose polarity and amplitude can be adjusted.


  • Ejection of picoliter to nanoliter volumes
  • Pressure range: 0-100 psi, smaller ranges available
  • Pulse duration: 2-999 m/sec (1 m/sec intervals), 0.1 – 99.9 sec, 0.1 – 99.9 min
  • Pulse initiation: external stimulator, front panel or remote pushbutton (or foot pedal)
  • Up to four injecting channels
  • Time mark: provides a useful index of the pulse duration (with selectable amplitude and polarity) or a synchro-out signal
  • Vacuum loading (optional): for multichannel models one channel can yield vacuum pulses which can be used for pipette loading
  • Size: standard 19“ rack
