An apparatus which can accurately determine the flow rate through a nipple orifice such as nipples which are used in conjunction with baby bottles. The testing apparatus utilizes a purging nozzle which will expel air into the nipple so as to remove any particulate matter so that a subsequent accurate reading can be obtained. The nipple is then placed on a test nozzle unit which is raised into contact with a nipple receiving head on a rotameter. When the nipple is placed in contact with the nipple receiving head, it will be maintained in contact automatically by means of air pressure in the test nozzle housing which ultimately will flow through the nipple orifice and into the rotameter. A reading on the rotameter will give an indication of the nipple flow rate. By a unique valving arrangement, the test nozzle will hold the nipple against the rotameter nipple receiving head so as to provide a uniform force and an accurate reading.
