To measure ECG and EMG the recommended systems are: | MultiLeadThis system includes the IX-BIO4 or the IX-BIO8 or the IX-ECG12 biopotential recorder. This configuration is a cost effective solution for those only interested in measuring ECG/EMG. The gain, high-pass filter setting and low-pass filter setting can be configured via software. |
 | Multi Lead ExpandableSeveral options are available depending on the research protocol and the need to acquire other signals (pressure, volume, flow, etc.) in addition to ECG. Our multi-channel systems have software configurable gains, high-pass and low-pass filter settings. These systems allow for simultaneous recording of up to 12 ECG leads (lead I, lead II, lead III, aVR, aVL and aVF and the 6 chest leads). |
Proper assessment of cardiac function and hemodynamic performance requires a measurement of pressure from within the heart and peripheral arteries. iWorx offers several sol
utions for measuring pressure including fluid‐filled pressure transducers, catheter-tipped micro pressure sensors and non‐invasive tail cuff pressure systems.LabScribe software with the Blood Pressure Module provides built‐in software routines to perform a number of arterial and ventricular pressure calculationsFluid-Filled Catheter System
The BP-100/102 blood pressure transducer is an economical and accurate device used to measure direct arterial or venous pressure in animals using the fluid-filled catheter technique. A precision laser-trimmed chip provides accurate and linear measurements over a broad range of pressures. Pressure changes in the vessel are transmitted within the fluid-filled tube to the pressure transducer and acquired for monitoring and further analysis. Tubing is available as small as 1 mm in outside diameter making this technique well-suited for measuring pressures in very small vessels. Blood pressure systems include the transducer, cable, data recorder and software.Bladder Pressure

 | IX-RA-834 RecorderThe iWorx RA Recorder is the foundation for iWorx advanced research systems. It include 4 transducer inputs, for recording 4 channels of Blood Pressure. Additional 4 channels of Blood Pressure can be recorded using the IA-400D amplifier and the 4 BNC inputs of the IX-RA-834. IX-RA-834 provides the ease of use and flexibility to speed your research. |
 | IX-404 RecorderThe iWorx 404 Recorder is an economical, high performance four channeldata recorders for use with a broad range of analog amplifiers. Therecorder offers 16-bit resolution at a maximum data collection speed of10 kHz, making it appropriate for most research applications. |

Software
LabScribe Blood Pressure Module
LS-30BP The LabScribe Blood Pressure Module acquires and analyzes data from blood pressure transducers. Data can be analyzed from ventricular and arterial signals in real-time.
The software automatically calculates common indices of function from the blood pressure signal where it can easily be exported to another program for further analysis.
