D330 MultiStim System

The modular MultiStim System D330 is intended to be used in labs where a variety of in vitro preparations in tissue baths or cell culture wells need field stimulation from a low impedance source. Each channel of the system employs the same time waveform, but each preparation receives a distinct stabilized stimulus. Modules for constant voltage and constant current stimulation are part of the system.

Scientists who want to precisely stimulate a variety of low impedance tissue preparations with various stimulating voltages or currents can utilize the modular and incredibly adaptable D330-MultiStim System. To enable the selection of a single earthing point and the avoidance of loops, the output channels are completely shielded and galvanically isolated from the ground.

The system offers two types of stimulation: continuous current stimulation and constant voltage stimulation (up to 100V at 1A-D333H) (up to 500mA from a 100V source - D343). To precisely monitor voltage or current, the system can be equipped with the D335 - Meter. To create pulses with changeable frequency and width that can be controlled as bursts using a gating waveform with variable repetition rate, length, or pulse count, a variety of timing modules are available. There are sockets installed to provide complete external control and synchronization, if necessary. The D337 19" rack-mountable unit, which houses the Gated Pulse Train Generators and up to ten stimulation channels, is a version of the D330-MultiStim System rack/case.

Because the system is modular, it can be divided into smaller components or extended to serve two sites.
