The IX2 700 is a dual channel microelectrode preamplifier designed to serve a wide variety of applications including: Single and Two Channel intracellular recording; Single and Two Channel extracellular recording; Ion-Selective Electrode Amplifier; Teaching application requiring ease of use.

The IX2 700 is a complete instrument with DC and pulsed current passing capability, filtering, electrode impedance testing, and a back-lit (for dark labs) LCD voltage and current meter .It is designed to serve a wide variety of applications including: Intracellular recording; and Extracellular recording (with optional headstage, 8024-15). A buzz button is included, but the optional BUZ-1 Universal Buzz Box adds amplitude, duration, and frequency features.
