Manufactured from durable, polycarbonate medical grade material, the handpiece is adapted to left- or right-handed operation, and ergonomically designed to minimize hand fatigue. Because the handpiece is actuated by contact pressure with the animal, there are no triggers to squeeze. Redundant safety features include an on/off switch and hand-activated “enable” safety switch. Components include a high-pressure, Kevlar®-lined hose, and an ultra-smooth orifice to assure optimal stream focus. The standard nozzle orifice measures .36 milliliter inside diameter, far smaller than a standard 18-gauge needle for less tissue damage.
