"Microflow is a miniaturized version of a flow cytometer (a common research or clinical laboratory instrument used for a range of bioanalysis and clinical diagnoses). Microflow can spot cells and biological molecules rapidly by using optical fibre-optic technology to detect them in a sample of liquid as they pass single-file in front of a laser--all within 10 minutes. Different detectors positioned at the point where the stream meets the laser can analyse the physical and chemical properties of molecules or cells in the sample. Unlike most current flow cytometers (which are used only in labs because they can weigh hundreds of pounds and take up as much space as three laser printers and an espresso machine), Microflow weighs less than 10 kg and takes up about the same space as a toaster. Microflow's small size and light-weight make it ideally suited for use in space, since it costs much more to launch heavier objects into space, and bulky objects are more difficult to stow aboard sleek spacecraft and the ISS."
