Buttons & Tethers for Rodents

Instech Vascular Access Buttons™ and Harnesses™ are built around miniature externalized ports that simply and cleanly connect an implanted rodent catheter to a syringe for direct boluses or samples, or to a tether for continuous access. Buttons have numerous animal welfare benefits and are our recommendation for any new system.
