: Vacuum-sealed quartz ampoules allow for the preparation of iron-lead and GaSb alloys without contamination from the atmosphere.
and glass particle contamination, researchers have developed devices like the Pocket Ampoule Cutter (PAC)
: Modified ampoule designs, such as the Immersing Sankaranarayanan–Ramasamy (ISR) method , are used to grow high-quality single crystals for semiconductors.
