Book a Demo


Used as a single-ended amplifier. It is designed for low-noise recording from excitable tissue and is suitable for EEG, ECG and extracellular recordings. It is ideal for teaching and is included in the Neuroscience Kit.

Included with the amplifier:

  • A headstage for use with high impedance electrodes. The headstage supports record, stimulate and impedance modes.

Note: The AC/DC Differential Amplifier (AM3000H) with a headstage designed for use with glass pipette microelectrodes is also available. You will need to purchase Glass Microelectrode Holders separately.


Key Features

  • The input can be amplified from 50 to 10,000 times in both DC and AC modes.
  • A high resolution DC Offset adjustment is available up to ±250 mV, using Fine and Coarse adjustment controls.
  • High Pass, Low Pass, and Notch Filters offer wide frequency selectivity.
