Borosilicate Glass Balls
Borosilicate Glass Balls are dimensionally stable, resist corrosion and chemical absorption. They can withstand high temperatures (up to 600° F). They are made from the special glass of the first hydrolytic class, which is well-known for its stability and pressure resistance, good workability and high thermal shock resistance due to its low rate of thermal expansion
Borosilicate glass balls are resistant to corrosion and remain absolutely neutral, even to aggressive chemicals in nearly all fields of chemistry. It is extremely resistant to water, acids, organic substances, halogens and it also has a high alkali resistance.
