Overview The Allflex 2EM-BT Auto Bottle Top Syringe is a repeating syringe that threads directly onto the medication bottle, delivering a consistent 2 mL dose with each pull of the plunger. Automatic self-filling with bottle attachment eliminates the need for a separate draw-up step, significantly speeding up vaccination programs, reducing product waste, and minimizing contamination risk. Compatible with 50 mL and 100 mL bottles only. The amber-colored barrel reduces UV sunlight exposure to protect light-sensitive medications, and the removable barrel makes cleaning easy between uses.
