This implantable button for rats connects three independent fluid channels simply by engaging the mating tether. It is the same size as the one- and two-channel rat Vascular Access Buttons™. Connect three 3Fr catheters to the 22ga inputs under the felt disk. The small ports, red, white blue, can be accessed manually using a syringe fitted with a PNP3M injector.

Group housing is possible with the optional aluminum cap (
