Abstract
According to the method of aseptic and antiparticulate opening of a sealed glass ampul, one end of the ampul is submitted to a powerful thermal flux produced by flame tongue generating sources on a very localized zone for a time period sufficient to obtain melting of the glass while maintaining the adjacent portion thereof at lower temperature for preserving its rigidity, such time period being the shorter the smaller that volume of gas contained in the ampul which is quickly brought to an increased temperature and pressure to cause the ampul to be opened up in the considered molten zone.
