Simcro V-grip vaccinators have a lighter action than finger-grip (FG) versions. This makes them ideal for big vaccinating jobs. All surfaces are rounded and lightly etched for good grip even in wet conditions. The 4.7mm tube spigot extends clear of the back handle, protected by the handle overlap. Barrel of clear polycarbonate. The tip of this model is metal, with standard half-turn Luer-lock needle attachment. Metal tip is stronger, and is also faster and more convenient for needle changes. Selectable dose. (Delivery tube and needles not supplied.)
