Making Physiology Happen


IX-RA-834 10+ Channel Recorder and Stimulator

The iWorx RA Recorder is the most advanced and feature-rich physiological data  acquisition system on the market. It comes standard with 4 BNC inputs, 4 Transducer inputs, 2 Event Marker inputs, 8 digital inputs, a low voltage and high voltage stimulator, 8 digital outputs, a built-in barometric pressure sensor and 4 iWire™ inputs. The iWorx RA exhibits the high resolution, low  noise and flexibility required for a variety of research applications including:

  • Cardiac Function
  • Hemodynamics
  • Isolated tissue and organ studies
  • Exercise physiology research
  • Metabolic function studies
  • Neuroscience
  • Oocyte clamp and epithelial voltage clamp applications

Recorder Features:

  • Built-in Barometric Sensor –allows for real-time compensation to pressure measurements due to changes in atmospheric pressure
  • Versatile – record multiple signals simultaneously (i.e. heart rate, respiration and pulse oximetry). See a list of compatible sensors.
  • Built-in Stimulators – built-in, software controlled low and high voltage stimulators for both human and animal experiments with a wide array of preset stimulation protocols
  • Longer Life Cycle – iWire digital design accommodates future lab technologies

Plug and Play Expandable

iWorx has developed a proprietary Serial Interface technology called iWire. iWire devices enable unparalleled expansion of your laboratory recording equipment by simply plugging in an iWire compatible device. Need to add 4 EMG channels to your protocol? No problem, simply plug in an IX-BIO4 iWire device. Need to record 12 leads of ECG? Simply plug in an iWire compatible 12-lead ECG device into one of the iWire inputs. A traditional data recorder would require 12 additional recording channels to accomplish this.

Current iWire devices include:



Versatile, Yet Easy-to-Use Software for Even the Most Advanced Analyses
LabScribe software is a powerful recording and analysis package that  features 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.

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.

Software Features

  • Intuitive Interface – LabScribe software display data through a customizable, user-friendly interface.
  • Real-Time Calculations – Monitor and observe functional parameters with an array of real-time calculations and user-defined computed channels.
  • Data Reduction – Analyze and reduce data and average and write selections of data to the built-in journal or directly to a text file.
  • Real-Time Annotations – Mark data during an experiment with freeform text notes.
  • XY Window – Any two channels can be displayed in XY format, online or offline.
  • FFT Analysis – LabScribe includes a Fast Fourier Transform feature for frequency analysis of any signal
