PICOSPRTIZER® III 

 

Pressure Systems for Ejection of 
Picoliter Volumes in Cell Research 

 

OPERATING MANUAL 

 

I. INTRODUCTION 

Please read this entire set of instructions before 
attempting to use this instrument for 
intracellular or extracellular ejections. These 
instructions cover all currently produced systems 
(single channel and two channel models). 
 
The Picospritzer III is a self-contained, rack- 
mountable system which supplies repeatable pressure 
pulses. Volumes dispensed are linear with time and 
pressure. The system can be initiated three ways: 
front panel push button, external stimulator (5 volt), 
or remote push button/foot pedal. The Picospritzer III 
pressure system was designed for rapid and 
reproducible ejections of picoliter to nanoliter 
volumes used in conjunction with intracellular or 
extracellular studies while avoiding the inherent 
desensitization of nerve cells which accompanies 
Iontophoretic methodology. 
 
Intracellular applications range from femtoliter 
ejections of RNA into small (50m diameter) cells to 
nanoliter ejections into oocytes. Extracellular 
applications range from picoliter applications of 
dilute neuroactive substances onto neurons during 
intracellular recording to the presentation of chemical 
stimuli to whole animals. 
 
The system comes complete with high speed valve(s) 
and the necessary tubing assemblies (less pipette and 
holder). It is designed to fit a standard 19" relay rack. 
The Picospritzer III comes fully adjusted and ready to 
use.
