The Prima Tech Prima Vaccinator MARC Premium Livestock Vaccination Syringe simultaneously injects and marks the animal all in one hand movement. When the dosage is administered, the squeezing of the livestock vaccination syringe activates the spray can, which releases a mark of paint onto the animal. This encourages safe administration practices, improves quality control efforts and saves the cost of missed animals. The livestock syringe includes 100 mL/20 mm Fast Fit, 250 mL/30 mm Fast Fit, 3 bottle collars (20 mm, 30 mm and 33 mm), metal luer lock nut and lube packet and comes packaged in a clear bag with a header card.
