Stimulators

 

Digitimer has a reputation for providing high quality electrical stimulators for both clinical and biomedical research areas. We now manufacture a range of constant current and constant voltage stimulators to suit the various requirements of our customers. Our low noise stimulus isolators are used worldwide for electrophysiology applications, however, we also offer a multi-channel stimulator for organ bath electrical stimulation as well as a range of isolated stimulators for clinical use.

DS2A-isolated-constant-voltage-stimulator-digitimer

 

DS2A Isolated Constant Voltage 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) used should be electrically isolated both from ground and from the trigger device. The DS2A meets both of these requirements and will deliver a low noise, …

DS3 Isolated Constant 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,…

DS4-Bi-phasic-stimulator-digitimer

 

DS4 Bi-phasic Stimulator
The DS4 has been developed to meet the needs of life scientists who require a stimulus isolator that can output a bi-phasic isolated constant current stimulus in response to an external command voltage signal, provided by a computer DAC via software. Such a requirement is already met by our NeuroLog System in the form of the NL512 Biphasic Buffer and NL800A Stimulus Isolators,…

DS5-Isolated-Bipolar-Constant-Current-Stimulator-digitimer

 

DS5 Isolated Bipolar Constant Current Stimulator
The DS5 isolated bipolar stimulator allows computer control of stimulus amplitude and timing parameters and has a maximum constant current output of ±50mA. It has been designed to speed up and enhance human peripheral nerve diagnostics by facilitating semi-automated nerve excitability tests. It also has roles in wider aspects of clinical neurophysiology research,

DS7A-DS7AH-HV-Constant-Current-Stimulator-digitimer

 

DS7A & DS7AH HV Constant Current Stimulator
Suitable as a general purpose electrical nerve or muscle stimulator, the DS7A provides up to 100mA constant current high voltage pulses of brief duration for percutaneous stimulation during investigation of the electrical activity of nerve and muscle tissue. The DS7A is also commonly used in pain research applications. The output current is continuously variable….

DS8-Biphasic-Constant-Current-Stimulator-digitimer

 

DS8R Biphasic Constant Current Stimulator
The DS8R is a new constant current, multi-mode, discrete pulse stimulator for human research studies involving nerve and muscle stimulation via surface electrodes. It features a high compliance voltage and can be triggered by a TTL compatible input, contact closure foot/hand switch or front panel “single-shot” button.

D185-MultiPulse-Cortical-Electrical-Stimulator-digitimer

 

D185 MultiPulse Cortical Electrical Stimulator
Now used worldwide as an effective tool for intraoperative monitoring (IOM) of the spinal cord, the D185 is the ONLY standalone surgical stimulator with FDA clearance for this technique. The D185 transcranial stimulator allows transcranial motor evoked potentials (MEPs) to be used in surgical procedures such as scoliosis correction, spinal tumour resection and thoraco-abdominal aortic aneurysm (TAAA) repair.

D330-MultiStim-System-digitimer

 

Digitimer D330 MultiStim System
The MultiStim System has been designed for use in laboratories where a number of in vitro preparations or cell culture wells need stimulation from a low impedance source. These studies are known as PUNCTATE or FIELD/BATH STIMULATION. The system uses a common timing waveform for each channel but different stabilised stimuli to each preparation.

NL800A-Constant-Current-Stimulus-Isolator-digitimer

 

NL800A Constant Current Stimulus Isolator
The NL800A is a battery powered, opto-coupled isolator (replacing the NL800), which has been designed for low noise applications such as in vitro and in vivo electrophysiology. It has a constant current output, with very high output impedance, making it suitable for stimulation through microelectrodes as well as with gross electrodes.
