Making Physiology Happen


IX-100B BioPotential Recorder

The iWorx 100B Data Acquisition System is a single channel recorder that  provides a cost-effective, high performance solution for dedicated applications such as Langendorff or working heart preps where only one biopotential recording channel is required.

The iWorx 100B has one isolated input channel and is equipped with a low voltage stimulator and an audio output. This recorder delivers the high resolution/low noise performance required for small animal cardiovascular research, Oocyte clamp nerve recording.

Resolution and Noise
The iWorx 100B uses a 16-bit A/D converter to sample data over its full input range of ±1V at speeds up to 200 kHz. Its low noise greatly reduces the need for gain and offset.

Versatile Bioamplifier
The iWorx 100B offers a wide selection of low pass and high pass filters* and is safe for human connection.

*IX-100B high pass filter values (MHz): 0.03, 0.3, 3, 30, 100

*IX-100B low pass filter values (MHz): 10, 20, 30, 40, 50, 60, 70, 80,
90, 100, 150, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 2000, 3000,
4000, 5000, 6000, 7000, 8000, 9000, 10000, 20000

Input Range
±1V, ±250mV, ±125mV, ±50mV, ±25mV, ±12.5mV, ±5mV, ±2.5mV

Low Voltage Stimulator
The iWorx 100B has a software programmable 16 bit, +/-5V stimulator (DAC). Parameters for stimulator, such as pulse width, frequency and amplitude, may be changed “on-the-fly” using handy controls located in the LabScribe™ software tool bar. Standard protocols include Pulse, Train, Step, Triangle and Ramp. In applications involving isolated heart, the stimulator may be programmed for pacing.

The iWorx 100B recorder is controlled by LabScribe software, a powerful recording and analysis software package. LabScribe has an intuitive, user-friendly interface for setting up acquisition screens, calibrating signals and analyzing data. Up to 128 channels of data can be displayed simultaneously at sampling rates as high as 100,000 samples/second.

A comprehensive set of analysis routines have been pre-configured making data analysis and interpretation quick and easy. Specific analysis modules for cardiovascular research are available to analyze pressure signals, blood flow data, ECG recordings, ventricular pressure-volume loops and sonomicrometry dimension data.
