Overview The Allflex 50MR2PO is a 50 mL reusable O-ring syringe built for reliable, long-term use in livestock vaccination and medication programs. Unlike disposable syringes, this metal-construction syringe is designed to be cleaned, sterilized, and reused — making it a cost-effective choice for operations that administer large volumes of injectable medications or vaccines on a regular basis. The replaceable O-ring seals maintain a consistent, leak-free plunger action and can be swapped out to extend the life of the syringe. Sold individually.
