10pcs Borosilicate Glass Test Tubes 16x150mm – Lab & School
10-Pack Clear Borosilicate Glass Test Tubes | 16×150mm
These precision-crafted borosilicate glass test tubes are built for reliable performance in school science classes, laboratory experiments, and sample storage. Made in Mainland China, each tube is manufactured from low-borosilicate glass for outstanding clarity, chemical resistance, and thermal stability — everything you need for accurate, consistent results.
Key Features
- Resilient Borosilicate Construction: Low borosilicate glass maintains structural integrity through repeated heating and cooling cycles, making these tubes ideal for routine and advanced chemistry work.
- Crystal-Clear Transparency: Highly transparent glass lets you visually monitor reactions, color changes, and precipitates at a glance — no guesswork required.
- Flat Rim Design: The smooth, flat rim supports efficient pipetting, minimizes residue, and makes liquid collection clean and straightforward.
- Universal Lab Fit: Sized at 16×150mm to fit the majority of standard test tube racks, centrifuge rotors, and shakers found in classrooms and laboratories.
- Strong Chemical Resistance: These tubes do not react with common laboratory acids or bases, ensuring reliable, contamination-free sample containment.
- Versatile Use: Perfect for chemistry experiments, culture growth, plant propagation, sample storage, and science fair projects.
