Mice are too small to turn rat swivel and tether systems; be sure to use infusion equipment designed just for them. The system features our 25ga swivel, which has the lowest rotational friction of any swivel on the market, as part of the mouse Vascular Access Button™ and tether kit. Our 2Fr mouse jugular vein catheter uses PU tubing that has been extruded for a perfect fit with the 25ga connector on the mouse VAB.
A spring-counter-balanced lever arm responds to the mouse's movements to keep the tether out of its way. We have included a high-performance Harvard Apparatus syringe pump to deliver the low flow rates used with mice.
A typical application setup is listed below. Add all the pieces to your quote, build your quote piece by piece, or call one of our experienced team members to help guide you through the system best suited for your needs.
