Description

Stopper Glass is a laboratory-grade closure designed for safe and reliable sealing of glassware. Manufactured from borosilicate 3.3 glass, it offers excellent resistance to heat and chemicals, making it suitable for routine laboratory applications.

The hexagonal cap design prevents the stopper from rolling off work surfaces, improving safety and convenience during laboratory operations. Its rounded and ground (chiseled) plug tip creates an effective sealing structure, ensuring tight closure and minimizing the risk of leaks or contamination.

This glass stopper is compatible with standard laboratory glassware and is widely used in educational, research, and industrial laboratories where secure sealing and durability are required.
