The visual inspection is completed by Keeping the ampule by its neck against very illuminated screens. White screens with the detection of black particle and black screens to the detection of white particles to detect heavy particles it may be essential to invert container but care has to be exercised to stay away from air bubble. The instrumental methods are based on principles of light scattering, light-weight absorption, electrical resistance as in coulter counter. A method which utilizes a movie impression projection could detects a read more shifting particle without the need of destruction of solution device.
