DIGITIMER - DS2A-Mk.II & DS3 Isolated Stimulators
Brief pulses of electricity are used in various biomedical research applications as a stimulus to excite nerve or muscle fibres
Several factors need to be considered when choosing the right stimulator
- In order to minimise artefacts introduced into electrophysiological data, it is desirable that the
stimulator 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 loss of the stimulus. In this event, a constant current stimulator may be more suitable
Our two isolated stimulators either provide constant voltage (DS2A-Mk.II) or constant current (DS3), giving you the ability to choose the stimulator which best suits your experimental needs
DS3 Constant Current Stimulator
- Four current ranges allow precise control of output between 2μA and 32mA
- Output discharge (Clamp) circuit prevents capacitance build-up during stimulus trains, which is important to prevent stimulus loss
- 90V compliance provided
