For low-noise recordings from excitable tissue using low impedance electrodes.
The Model 3000 AC/DC Differential Amplifier is designed for low-noise recordings from excitable tissue using low impedance (<1.5 MΩ) electrodes. When paired with an optional x10 gain headstage, the Model 3000 is perfect for single cell recordings using high-impedance glass or metal microelectrodes.
This single-channel amplifier is packed full of features to accommodate your specific instrumentation requirements, yet fits into a compact enclosure for convenient placement in the lab. The standard input consists of a twisted-pair cable with an active shield. The ends of the cable are left bare to be wired to your input device.
As an option, a headstage can be used to pre-amplify the input signal for high impedance glass or metal microelectrodes. The input mode can be set for either differential or single-ended recordings.
External stimulus generators can be easily used with the Model 3000 via the front panel stimulus input BNC. Stimulus mode channels any signal present at the stimulus BNC directly to the electrodes, bypassing the internal recording circuitry. At the same time, the amplifier switchs to a current monitor mode, and measures the actual current passing through the electrode. Both stimulus and recording modes can be controlled through an external gate signal, allowing for computer controlled switching.
