This implantable button for rats connects four independent fluid channels simply by engaging the mating tether. It is the same size as the one-, two- and three-channel rat Vascular Access Buttons™. Connect four 3Fr catheters to the 22ga inputs under the felt disk. The small ports, red, white, blue, and green can be accessed manually using a syringe fitted with a PNP3M injector.
The mating tether snaps into the button with magnets to minimize the force on the animal. Connect a 25ga dual channel swivel for continuous to two lines or a single channel swivel for continuous access to one; access the other lines through PinPorts at the top of the tether for intermittent sampling or dosing. Use a five-channel swivel for continuous access to all four channels.
Group housing is possible with the optional aluminum cap (
