IR-183A Intracellular Recording Amplifier
CygnusTech offers two versions of the NeuroData current clamp amplifier, a single and a two channel version. The electronics are identical except that the dye injection feature is shared on the two channel model and the IR-283 includes cross decoupling circuitry between the two channels to help eliminate artifacts caused by common ground impedances and capacitive coupling in double barrel electrodes.
Both models feature a three way cell penetration system consisting of an AC induced oscillation mode, a constant current pulse , and a high voltage pulse mode. Control is provided for intensity, duration, and polarity (except AC). The instruments are supplied with a hand held switc for activation, an optional foot switch is available. The headstage incorporates a break out relay which grounds the input remotely or when power is off to prevent damage and to allow direct access to the electrode from an auxiliary input.
