Blood Flow in the Rat

Mouse

View Mouse / Rat Products >

The development of small ultrasonic transit-time flowprobes has enabled blood flow measurement in the small vessels of the rat. The flowprobes demonstrate measurement stability and high resolution. Hundreds of rat studies have been published using Transonic flowprobes. Below are the protocols and technical notes included in the popular workbook, "Fundamental Techniques for Hemodynamic Studies in the Rat (4th edition, 1996)."
