Liquid transfer devices

摘要: A liquid transfer device of disposable one-time use form to conduct a biochemical diagnostic or other assay comprises two flow channels (10, 110, 210; 20, 120, 220) leading from respective pair channel ends common site (30, 130, 230) and operable deliver this in sequentially timed manner following simultaneous application such the ends. Typically respectively different reagents (11, 111, 211; 21, 121, 221) are incorporated channels, third reagent (31, 131, 231) at site, whereby sample be assayed respect particular content can applied immobilised by reagent, subsequently subjected one detect any interest, finally exhibit for user detected content.
