A-M Model 1700 Differential AC Amplifier

The Model 1700 Differential AC Amplifier contains 4 independent amplifier channels in a single enclosure enabling the researcher to record multiple signals simultaneously. Each channel contains a high-gain, low-noise differential stage followed by low-pass, high pass, and notch filters. A connection is also provided for a stimulator input so that recording or stimulating through the same electrode is possible without having to change cabling.

A-M Model 1800 2-Channel Microelectrode AC Amplifier

The Model 1800 Microelectrode AC Amplifier is a two-channel, differential amplifier intended for extracellular recording and/or stimulating with high impedance metal microelectrodes in research and teaching applications. Ideal for single-cell spike recordings, it can also be used in a number of research or teaching applications requiring extracellular neurophysiological recording from excitable tissue such as nerve, muscle (EMG), EEG, EKG, and ERG recordings.

A-M Model 3000 AC/DC Differential Amplifier

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.
