Qosina offers a variety of valves that are in stock and ready for immediate delivery. Qosina part # 90403 is a component ideal for procedures involving liquid sampling. Materials consist of an ABS red male luer lock body, a polycarbonate female luer lock body and silicone valves. When the needleless swabbable luer activated valve is accessed by a male luer lock or male luer slip syringe, the internal duckbill check valve allows fluid samples to be taken. The one-way duckbill prevents accidental injection through the connector. The needleless valve seals against any back pressure upon disconnection of the syringe. Qosina offers a large selection of valves and valve accessories to satisfy your project requirements.
