These reusable Borosilicate Glass test tube have a heavier wall. They therefore have considerable mechanical strength & excellent thermal shock resistance.
Borosilicate Disposable Culture Tubes
| O.D. × Length (mm) | Wall Thickness (mm) |
|---|---|
| 10×75 | 0.6 |
| 12×75 | 0.6 |
| 12×100 | 0.6 |
| 15×125 | 0.8 |
| 15×150 | 0.8 |
