Light arc for tail vein injection is a novel technique used to administer drug substances to black strains of rodents. The black strains of rodents have a darker tail which makes it difficult to spot the caudal vein due to color contrast. This illumination problem is solved by Conductscience’s Light Arc which distributes a uniform light over an angle of 180° around the subject’s tail.
The light arc stands on a flat base connected to the power source. A Broome-style handler is placed in the center to restrain the subject. The arc is equipped with 10 RGB LEDs, approx. one every 2cm. The color contrast is regulated by the intensity of the primary colors; it can be adjusted with red, green, and blue knobs for the optimal contrast of the veins.
Available in Red, Blue, Green coloration, Conduct Science offers the Light Arc for Tail Injection. The restrainer is not included. The restrainer holder is adjustable to be able to hold different size restrainers.
