RG® Borosilicate Test Tubes 25 × 150 mm — Pack of 6

PRODUCT INFORMATION

About this product

These 25 × 150 mm borosilicate glass test tubes provide a larger working volume for laboratory samples, mixing and controlled heating. The pack of six is suited to small practical groups, demonstrations and routine laboratory work where several matching tubes are needed without purchasing an institutional-size carton.

Buyers often describe this product as a large glass test tube, 25 mm laboratory tube or borosilicate chemistry tube. The clear, rimmed construction allows easy observation and handling with a compatible rack or holder. Confirm the required diameter, length and pack quantity before ordering, and always inspect laboratory glassware for chips or cracks before heating.

The pack of six can support a small student group, comparison samples or repeated practical work. Its 25 mm diameter requires a rack with suitably large openings, so a common narrow test-tube stand may not fit. Clean the tubes with non-abrasive laboratory methods and avoid impacts during storage and transport.
