Borosilicate Laboratory Glass Tube 2.23g/cm3 Density 820°C Softening Point for Pharmaceutical and Industrial Applications
Borosilicate tube glass is a specialized glass formulation containing high concentrations of boron trioxide and silica, making it more heat resistant than standard glass types while remaining safe and environmentally friendly.
Compared to ordinary glass, borosilicate glass offers superior mechanical properties, thermal stability, water resistance, alkali resistance, and acid resistance without toxic side effects. This revolutionary base material finds applications across chemical, aerospace, military, medical, and household sectors.
| Stage | Process |
|---|---|
| 1 | Silicate forming |
| 2 | Glass liquid forming |
| 3 | Clearing |
| 4 | Homogenization |
Glass liquid flows from the furnace through the throat into a rotating cylinder, forming tubular shapes under controlled rotation speed. The tubular shape is stretched and formed into glass tubes via graphite guide rollers.
Glass liquid flows from the throat into a heat-resistant alloy pipe, forming tubes under compressed air function.
