Acids and alkalis cause most substances to go up in smoke. But not specialty glass: Even after six hours in boiling hydrochloric acid, it is virtually undamaged. This makes it an indispensable material for chemical applications with highly reactive substances.
Where is it used?
Protection for medicines
Delamination, the detachment of barely visible flakes from the inner glass surface of a pharmaceutical vial, is a rare phenomenon that only occurs under certain circumstances as a result of interaction with the drug. This must be minimized to ensure patient safety. Glass with a chemically homogeneous inner surface safeguards against this risk.
“When glass is used in aggressive environments, or with sensitive substances, the chemistry must be right.”
