Rodent Tubular Holders are used to hold and/or restrain small rodents such as mice or rats during experiments or procedures. Tubular type holders are used to restrict the animal from turning or moving, while reducing injury caused by animal movements. The unique design of the vented tapered nose fixator provides easy access for animals, while also allowing animals to feel safeand breathe more easily. The tail is able to stretch, helping the animal to stay still for over 1 hour.
