HSCo supplies laboratory glass test tubes in two glass types: neutral glass for everyday work, and borosilicate glass 3.3 for heating and harsher chemicals. They come in sizes from 6 × 40 mm to 20 × 220 mm and are sold by the carton, for laboratories, colleges, chemical and pharmaceutical units.
Neutral glass or borosilicate 3.3?
- Borosilicate glass 3.3 expands very little when heated, so it takes direct heating and sudden temperature changes far better, and resists most chemicals. Choose it for heating, boiling and reactive samples.
- Neutral glass suits storage, mixing and routine tests at room temperature, at a lower cost.
