Abstract

The invention relates to testing apparatus (1) for testing a container (2) of a suspension of a substance (3). The substance may in particular, but not solely, comprise a pharmaceutical substance. The substance (3) is suspended in a propellant (4), which is under pressure. The container (2) itself comprises a body (5), which defines a chamber and has a valve stem (6), which extends from a head of the body. A metering chamber is selectively communicable, by means of the valve stem, with the atmosphere and the chamber (7). The valve stem providing via a L-shaped conduit, which extends between the free end and the side wall thereof the outlet of the container (2) through which metered doses of the substance are released from the container (2). The testing apparatus (1) includes a gallery (8) for communicating, in use, in a fluid-tight manner with the said valve stem and actuating means, in use, actuating the valve stem so as to discharge a metered dose of substance and/or propellant into the gallery, repeatedly if necessary, until the pressure within the gallery is substantially equalised with the pressure within the container (2). The testing apparatus further includes pressure-measuring means (9) in communication with said gallery to provide a measurement of the pressure therein and hence the pressure within the container (2).
