Glass balls are used for technical applications that call for high chemical stability. One of the benefits of glass balls is that they demonstrate permanent stability for all pH solutions, from alkaline to acidic.
Common applications for glass balls are valves for metering pumps in the chemical industry, roller conveyor technology for the photography industry, and sprays and dispensers for cosmetics and pharmaceuticals.
Special natron glass (also known as soda lime glass) balls are often used in the chemical and pharmaceutical industry. These balls are even used in pressure vessels or measurement instruments.
Borosilicate glass balls – known as boro – have superior resistance to aggressive chemicals, high temperatures or sudden temperature fluctuations. For that reason, you will often see them used in special applications such as in the cosmetics industry or medical sector.
