Product Insights

The Zol Stock Art glass test tubes measure 22 mm in diameter and 120 mm in length and are sold in a pack of three. They are made from clear borosilicate glass, offering good chemical resistance and allowing easy visual inspection of contents. Because they are fragile, they require careful handling and proper storage to avoid breakage, and they are not suitable for high-temperature autoclaving beyond the glass rating.

Comparative Analysis

These 22 mm × 120 mm glass test tubes from Zol Stock Art occupy a niche in laboratory and educational supply markets by combining clear, reusable borosilicate construction with a compact three-piece pack that rivals bulk glassware in durability while remaining affordable.
