Manufactured with Lycra®/spandex, these jackets are suitable for a wide range of continuous intravenous infusion applications. The Mouse Jackets have a double layer of Lycra®/spandex for additional durability. The jackets close by means of a Velcro® fastener and supplemental hooks provide additional security and better fit. Available in five sizes for rats and three sizes each for hamsters and mice, jacket inserts are available for both the rat and mouse jackets. The inserts are for studies where test articles are dermally applied. They are a non-occlusive covering for the application site that helps prevent oral ingestion while allowing in-line investigations to be carried out with ease.
