Universal Isolated Stimulator Output for Physiology Lab

The Universal Isolated Stimulator Output is designed to produce ungrounded, isolated, or floating electrical stimuli while preventing interference with simultaneously recorded biopotentials such as ECG, EMG, and EEG. It can be connected between a stimulator and stimulation electrode and is compatible with virtually any stimulator that provides a trigger pulse with timing and pulse width corresponding to the stimulus duration. It can also be connected to a TTL trigger output generated by computer software for use as a power amplifier. The unit provides adjustable output voltage ranges and supports positive, negative, or alternating stimulation. Manufactured by Atico Export with a focus on precision, durability and consistent performance for physiological research and experimental laboratory use.
