A-M Systems Amplificateur intracellulaire Model 1600

The Neuroprobe Amplifier Model 1600: Designed to surpass the exacting requirements of intracellular neurological studies and provide the research scientist with versatility, accuracy and ease of operation.

The instrument consists of a high input impedance amplifier combined with current injection and bridge balance circuitry, allowing simultaneous stimulation and recording through the same electrode. The internal Dual-Function Transient Control and the DC balance Control assure extremely precise recordings during current injection without requiring an external bridge or a differential input oscilloscope. High-resolution ten-turn potentiometers are used for the DC Offset, DC balance, Current Injection, and Capacitance Compensation controls. Measure electrode resistance and adjust capacitance compensation using the internal 100 Hz test pulse. An easy to read Digital Panel Meter produces a highly accurate display of membrane potential, injected current or electrode resistance

The Neuroprobe Amplifier's advanced current injection system, adjustable to 0.1 nA resolution, allows external switching of both internal and external current sources. The total current from all sources can be displayed on the Digital Panel Meter prior to injection. This capability allows the user to inject the exact amount of current desired. Depending upon the requirements of the experiment, the user can also select either momentary or continuous injection.

This Iontophoresis Adapter allows the researcher to apply greater voltages to the micropipette for iontophoretic injection of drugs or dyes, or any other application where currents greater than those provided by the Neuroprobe Amplifier are required.
