E-Z Trac Ultraspheres™

Non-radioactive colored microspheres, Ultraspheres™, are optimized for methods requiring precise color formulation for discrete particle-based counting by light microscopy or microscopic color image analysis. Ultraspheres™ are formulated to strict standards ensuring size uniformity of less than 5% CV, dye incorporation maximizing color intensity, and chemical stability in most aqueous environments. Microspheres exhibit densities of approximately 1.05-g/ml and are supplied in 0.05% Tween 80 saline solution. The E-Z Trac Ultraspheres are ideal for experiments that involved various sizes of spheres or a more unique experiment where the tissue or clean microsphere samples are to be analyzed under a microscope.
