Description
The Glass Test Tubes Without Rim from Osmosis Scientific are precision-manufactured laboratory tubes crafted from high-grade Boro 5.1 borosilicate glass. These tubes provide excellent thermal and chemical resistance, making them ideal for routine laboratory applications such as culture handling, sample storage, chemical processing, and general lab workflows.
Designed without a rim, these test tubes have a smooth open end, simplifying insertion into racks, holders, or media dispensers. Their cylindrical shape and uniform wall thickness ensure reliable performance during handling and transfers, while the rounded bottom allows secure placement in test tube racks or heating blocks.
Available in a broad range of diameters (10 mm–25 mm) and lengths (75 mm–200 mm), these tubes offer flexibility for various laboratory requirements — from small-scale analysis to bulk sample preparation.
The Boro 5.1 glass construction delivers robust durability with resistance to aggressive reagents, temperature fluctuations, and repeated handling. Whether used in microbiology labs, clinical sample prep areas, educational experiments, or analytical workflows, these glass test tubes without rim deliver reliability, clarity, and consistent performance.
