title: An inexpensive picoliter-volume pressure ejection system.
abstract: A picoliter pressure ejection system, which is constructed from readily available and inexpensive components, is described. Pressure pulse duration and interpulse interval are controllable by either internal circuitry or by external signals from stimulators or computers. The control features and linearity of ejection volumes are similar to those of more expensive commercial units.
