Borosilicate Glass Tubing 7mm Outer Diameter x 24"H Case of 180 Tubes By GSC International Inc.

This Borosilicate Glass Tubing case contains approximately 180 high-quality tubes, ideal for classroom STEM experiments, professional laboratories, and glassblowing projects. Each tube measures 7mm in diameter and 24 inches (610mm) in length, offering uniform sizing for educational demonstrations, chemistry experiments, and craft applications.

Borosilicate glass provides superior thermal resistance compared to flint or soda lime tubing, making it safer for high-temperature experiments. The cut ends are not fire polished, giving flexibility for custom applications while maintaining structural integrity.

Perfect for connecting laboratory equipment, bending, cutting, or stretching for a variety of uses, these tubes are durable and lightweight for easy handling and storage. This bulk case ensures a reliable supply for classrooms, labs, or repeated experimental use.
