  1. DS3 Isolated Current Stimulator

    Brief pulses of electricity are used in various biomedical research applications as a stimulus to excite nerve or muscle fibres. In order to minimise artefacts introduced into electrophysiological data, it is desirable that the stimulator/stimulus isolator should be electrically isolated both from ground and from the trigger device. The voltage required to send current through tissues can vary greatly, making it important to have control over the stimulus driving force. Large impedance variations during an experiment can result in a lack or reproducibility or total loss of the stimulus. In these circumstances, a constant current stimulator like our DS3 would be recommended over our DS2A.
