The D330 MultiStim System is a modular and highly versatile multi-channel stimulator designed to be used by biomedical scientists who wish to accurately stimulate a number of low impedance tissue preparations with different stimulating voltages or currents. The output channels are fully protected and galvanically isolated from ground so that a single earthing point can be chosen and loops avoided.
The system provides a choice of modules for either constant voltage stimulation (up to 100 V or 1 A) or constant current stimulation (up to 500mA from a 100 V source). The D335 - Meter can be fitted into the system to allow precise voltage or current monitoring.
A selection of timing modules are available to generate pulses, variable in frequency and width, which can be controlled as bursts using a gating waveform, variable in repetition rate and duration or pulse count. For ease of use, most modules have an error indicator to warn of incompatible settings or an overload condition. Sockets are fitted to allow full external control and synchronization if required.
The D330 MultiStim System rack/case is available in two sizes. A 19 inch rack-mountable unit that can house up to ten stimulation channels and a ‘half-width’ bench-top unit capable of taking up to four stimulation channels along with the Pulse Train Generator and Gating modules.
The D345 PowerStim is an extension of the D330 MultiStim System range, and provides the controlled high power stimuli from a low impedance source needed for Field Stimulation of preparations in extra low impedance baths. It provides up to 80 V at 2.5 A from each of its four overload protected channels and these outputs can be externally combined to give two 5A channels or a single 10A.
The modularity of the system allows a system to be extended or split between smaller units for two sites.
Safety Information
To comply with laboratory safety standards, the complete D330-MultiStim System must be completely enclosed. Therefore we offer matching D330-1 and D330-2 Single and Double Blank Front Panels to complete the front panel aperture. We cannot sell a system with less than a completely filled front panel.
