Amber borosilicate glass is primarily used for storing light-sensitive chemicals, reagents, and pharmaceuticals in laboratories and industry, thanks to its excellent UV protection, thermal shock resistance, and chemical inertness, making it ideal for applications needing protection from degradation, heat, and aggressive substances like acids and alkalis. It’s common in pharmacies, research, and holistic medicine (like essential oils) for durable, safe, and contamination-free containment.
