They are mainly used for scribing marks on metal surfaces, cutting particles from collodion and for single particle manipulation. Because the tip is rather fragile, it bends or breaks frequently. Many of these needles should be kept on hand since a few may be necessary to complete manipulation of a single particle. Not only are tungsten needles used for particle manipulation, but they can also be used when working with embryos and for glass blowing.
