quartz funnel

The quartz glass is the fine acid-proof materials, except the hydrofluoric acid and 300 above the phosphoric acid, any density's acid solution until achieves the boiling point, corrodes to the quartz glass minimum, although also the ability neutral substance's corrosion, it has with the alkali should, but the reaction rate is quite small, therefore, the quartz glass is one kind good bears the chemical corrosion material.
