Merit Medical offers a variety of syringes to meet various clinical needs. Our patented VacLok vacuum pressure syringes allow clinicians to lock the plunger in multiple positions for a negative pressure vacuum. This feature minimizes hand fatigue while increasing procedural efficiencies. VacLok vacuum pressure  syringes have a polycarbonate barrel for clear visibility, fixed male Luer connector, and are available in 10, 20, 30 and 60 mL sizes.
