Overview

A stimulator designed to provide electrical stimulation in physiological and pharmacological research experiments. It is equipped with a booster amplifier to allow field stimulation up to a maximum output of 50 V, and has input terminals that allow signal mixing and modulation with an external signal.
Additionally, its output can be insulated from grounds via an Isolator (purchase separately).

This product is not currently available for purchase in Europe.

Other types of nerve and muscle stimulators including ADInstruments stimulators are also available.

Features


  • Provides stimulation options including:
    • Train stimulation - single pulse, paired pulse and train pulse.
    • Biphasic pulse stimulation.
    • Field stimulation with a maximum output of ±50 V and 400 mA (built-in booster amplifier) with any stimulation waveform.
  • Generates mixed and modulated stimulus waves when combined with an external signal.
  • Fine adjustment of output voltage up to 10 V.
  • Output terminal for connection with the ML1101 Stimulus Isolator that:
    • Provides constant voltage or constant current output.
    • Provides stimulus of positive or negative polarity.
    • Provides excellent input and output linearity.
    • Features a built-in over current alarm.
    • Displays the amount of power that goes through the isolator.
