The Perkin Elmer Tri-Carb 2900TR Liquid Scintillation Analyzer is a computer-controlled benchtop liquid scintillation analyzer for detecting small amounts of alpha, beta and gamma radioactivity. Includes computer with proloaded software. It is designed to accurately quantify the amount of radioactive material present in a sample by measuring the light pulses generated when the radioactive material interacts with a scintillation solution. The Tri-Carb 2900TR provides precise and reliable data to support a variety of applications in the fields of biology, chemistry, and environmental research
