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 and nanoliter volumes used in conjunction with intracellular or extracellular studies while avoiding the inherent desensitization of nerve cells which accompanies Iontophoretic methodology. The Picospritzer 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 also comes fully adjusted and ready to use. It includes a self-contained regulator assembly, which can be used to increase or decrease pressure simply by rotating a knob. Pulse is setup using a three-digit thumbwheel for duration and a three-position toggle switch for range setting (millisecond, second or minute). The valve box(es) are connected to the corresponding jack in the rear of the instrument and pneumatically to the compressed gas regulator via tubing assemblies.Millisecond, Second and Minute Operating times. Resolution to 1 millisecond. Pulses as short as 2 milliseconds. Pulses Initiated from Panel Pushbutton, External Simulator or Remote. Internal timer can be externally triggered. 5-volt Marker Output. Channels independent when operated externally. Universal Power Supply Matching available, line voltages ranging from 90 to 250 volts AC, 50-60 Hz. Single, Two-Channel, and Vacuum Loading Models available. Single-channel unit upgrade.
