Millar Mikro-Tip® pressure catheters with pressure sensor(s) provides high-fidelity cardiovascular pressures (the heart and vascular system) at the source in small animals. We offer pressure catheters for intrauterine, intracranial and arterial blood pressure monitoring, amongst other research applications. 

Book a Demo

Overview

Millar Mikro-Tip® pressure catheters provide an ideal solution for measuring highly accurate pressures. Whether measuring arterial and ventricular blood pressures, spinal pressures, tumor pressures or airway pressures, a high-fidelity pressure sensor from Millar is a necessity for your research. 

  • Single and multiple high-fidelity pressure sensors side mounted at the catheter tip
  • Mice, rats and larger animal models such as pigs and sheep
  • Sizes from 1 F to 5 F
  • Straight and curved tips without pigtail

Catheters require Catheter Interface Cables for connection to any ADInstruments  bridge amplifier . Record and analyse blood pressure data quickly and easily using the Blood Pressure Module that is included with LabChart Pro software. A Pressure Gauge kit which provides the necessary items to calibrate the Mikro-Tip® pressure transducer is available.

Cost-effective Millar Mikro-Tip Catheters can be reused for multiple experiments. Our best selling catheters include SPR-320 for rats, SPR-671 for mice and the smallest sensor tip pressure catheter in the world, the SPR-1000, also for mice. 

Non-repairable discount options are available for Pressure Catheters (SPR-407, SPR-320 and SPR-671 only). Contact us to find out more and if this is the right option for you. More information on Millar repair policies.

Millar Mikro-Tip Catheters require a certain level of care to ensure accuracy and the anticipated lifespan of your catheters. For a few best practice tips to help get you started with your catheters, see our guide here.

Millar have recently simplified their range so that all pressure catheters now work with the Low Profile pressure connector cable, rather than the Viking cable.

Choose from single or dual pressure catheters.
