Qosina carries an extensive line of stopcocks with 1-, 2-, 3-, and 4-way fluid direction. Connections include NRFit™, ENFit®, male luer slip, male luer lock, male luer with spin lock, rotating male luer lock and female luer lock and tubing ports ranging from 0.118-inch (3 mm) ID to 0.26-inch (6.6 mm) ID. Some of our stopcocks are equipped with a needleless injection site, which includes a luer-activated valve that allows for easy control of fluids. Once the stem of a male luer is connected to the female luer lock needleless injection site, the valve opens, allowing for the flow of fluid. Once disconnected, the valve is closed, stopping the flow. Many of our stopcocks are compliant with the ISO 80369-7 standard.
