Qosina has added a series of polysulfone stopcocks, including a one-way, three-way and four-way to its inventory of fluid control components. 

The stopcocks feature a white, high-density polyethylene handle designed to clearly indicate open or closed. Polysulfone provides more chemical resistance than many other plastics, according to the company,

The one-way low profile stopcock has a female luer lock inlet and rotating male luer spin lock outlet.  The three-way version has two female luer locks and a male luer slip, including three caps and the four-way stopcock features a radiation grade tint with two female luer locks and a male luer slip. 

Edgewood, N.Y.-based Qosina provides stock OEM disposable components to the medical and pharmaceutical industries including connectors, luers, caps, clamps, adapters, stopcocks, valves, swabs and spikes.
