tempdef: a device, or set of devices, connected as part of a single object, that are used for a common purpose such as separating components in a mixture, spinning and/or measuring, e.g., a centrifuge, a liquid chromatography mass spectrometer. .
rem1: At the meeting in Philly I wrote that BS said that it should be a count term, such as a set of instruments. By allowing connected devices we avoid the problem of things like LCMS being considered separate items, since we have a number of discrete functions like separation, making things fly, monitoring the charge and mass of what flies etc that are all part of a single machine.
