Picospritzer III

Mikroinjektor (General Valve / Parker Hannifin)

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 (see below)
  • Pulse duration:       2 - 999 ms (1 ms intervals)
                                            0.1  - 99.9 s
                                            0.1 - 99.9 min
  • Pulse initiation : external stimulator, front panel or remote push button (or foot pedal)
  • Up to two injecting channels
  • Time mark: provides a useful index of the pulse duration (with selectable amplitude and polarity) or a synchro-out signal
  • size: standard 19" rack


Ordering information

The Picospritzer is available in One- or Two-channels versions, each of which in two pressure ranges:

A. Single Channel (Basic Model): The PICOSPRITZER III comes complete except for pipettes and pipette holders. One valve box and cable is supplied as well as the tubing required to connect it to the front panel mounted regulator assembly and to a pipette holder. 12 feet of ¼ inch OD tubing are supplied to make the connection between the regulator assembly and the compressed gas supply (maximum 150 psig). Expansion capability for a second valve box is built in.

P/N 051-0500-900      0-100 PSI regulator

P/N 051-0530-900      0-30 PSI regulator

B. Two Channel: This PICOSPRITZER uses the same electrical chassis as the single channel but
includes two valve boxes and the tubing assemblies to connect both to the front panel regulator and to pipette
holders (pipettes and holders are not included).

P/N 052-0500-900      0-100 PSI regulator

P/N 052-0530-900      0-30 PSI regulator

Either system comes complete with high speed valve(s) and the necessary tuning (less pipette and holder).

Standard pipette holders are available for pipettes with diameters of 1.0 mm to 2.0 mm in 0.2 mm increments (order separately).
