The SPR-838 rat pressure-volume catheter is the market leading solution for simultaneously measuring left ventricular pressure and volume in rats. Built to the highest quality standards, the catheter combines a proven Mikro-Tip® pressure sensor with four electrodes to collect real-time pressure-volume data.
The SPR-838 is Millar’s most popular catheter for performing pressure-volume studies in rats. With a pressure sensor diameter of 2F and 1.1F along the catheter body, this model offers the ideal combination of durability and ease of use for hemodynamic studies utilizing rats 350 g and larger.
The SPR-838 provides a 12.5 cm usable catheter length and a 9 mm electrode spacing for optimized ventricular volume measurement in standard-sized rats. For smaller animals and/or right ventricular studies, consider the SPR-869 pressure-volume catheter.
Millar Instrument’s is dedicated to finding ways to increase customer access to the highest quality tools for performing successful research. This is why Millar offers the No Repair purchase option on the SPR-838 and other select small animal pressure and pressure-volume catheters. To learn more about the No Repair option, contact your sales representative or distributor.
For complete hemodynamic analysis, use the SPR-838 mouse pressure-volume catheter with the MPVS Ultra® or MPVS Ultra® Single Segment system, PowerLab 35 Series data acquisition system with LabChart Pro and the PV Loop analysis module.
