A dual-chamber device (100) for receiving and containing a liquid, particularly urine, employs a generally cylindrical body (102) having detachable top and bottom covers (104, 106) and an internal, transverse, funnel-shaped wall (140). The transverse wall (140) has a central circular orifice (146) and divides the body into lower and upper chambers for respectively receiving and retaining fore-stream and mid-stream urine liquid samples. A floatable orifice stopper (160) in the lower chamber (144) is responsive to fore-stream liquid filling the lower chamber to a predetermined level for closing the orifice, so that subsequent, mid-stream urine liquid is received into the upper chamber (142). An annular float (180) beneath the orifice stopper assures proper stopper closing of the orifice. (FIG.1)
