Model TSP48-12 is a 48" long, 12cc pole syringe. Syringe poles operate just like a syringe you find at the doctors' office except they give you much greater reach. Gently push the needle into the animal and control the injection from the thumb operated trigger at the opposite end. There is no additional pressure on the animal during the injection. Our syringe poles are made from aircraft grade thick walled aluminum tubing and will pass through a 3/4" opening. Comes with a syringe kit (2 syringes and 5 needles).
