The Syringe Injection System is designed for controlled administration of substances into rodents prior to imaging procedures using our in vivo imaging platforms. This system helps provide accurate dosing and reduced stress to the animal, supporting effective preparation for imaging studies such as bioluminescence, fluorescence, microCT, or ultrasound. Its design and compatibility with standard syringes make it a valuable tool for researchers conducting longitudinal studies, pharmacokinetic analyses, or biodistribution assessments.
