Transparent Glass Tube
Inquiry
Product introduction
Transparent glass tubes are mainly composed of silicon dioxide (SiO₂) and boron oxide (B₂O₃) (accounting for 78-80% and 12.5-13.5% respectively), supplemented by aluminum oxide (Al₂O₃) and alkali metal oxides (such as Na₂O, K₂O), and a uniform and stable glass structure is formed through a high-temperature melting process. Its core features include:
High light transmittance: Visible light transmittance is as high as 92%, suitable for microscopic observation, spectral analysis, and other scenes requiring optical transparency 27.
Temperature resistance: The thermal expansion coefficient is as low as (3.3±0.1)×10⁻⁶/K and can withstand an extreme temperature difference of -50℃~500℃ (3 times that of ordinary glass), and there is no risk of deformation or crystallization at high temperatures 15.
Chemical stability: Except for hydrofluoric acid and hot phosphoric acid, it can resist strong acid and alkali corrosion and maintain permeability after long-term immersion to avoid contamination of experimental samples or industrial materials25.
Mechanical strength: It has high hardness and strong pressure resistance and can be processed into capillaries with ultra-fine inner diameters (such as 0.6mm) for single-cell capture, microreactors, and other precision scenarios24.
