Neuro Data offers two models of intracellular recording amplifiers: the Model IR-183 single channel amplifier and the Model IR-283 dual channel amplifier.
Both models feature a three way cell penetration system, which consists of an AC induced oscillation mode, a constant current pulse mode, and a high voltage pulse mode. Controls are provided in each mode for pulse duration, pulse intensity, and polarity (except in AC induced oscillation mode). Both models also come equipped with a transient suppression system, a headstage grounding switch, a dye injection system, and a trace locator circuit.
