Transparent Narrow Neck Quartz Glass Flask for Laboratory

1. Purity:

SiO2 content is more than 99.9%, transparent quartz glass tube can reaches above 99.95%.

2. Temperature :

Softening point temperature is about 1730 degrees Celsius ,1250 degrees Celsius in a long time used ,short-time maximum use temperature is up to 1450 degrees Celsius.

3. Anti-corrosion:

Quartz glass is acidic materials, except hydrofluoric acid and 300 degrees Celsius thermal phosphoric acid, on any other acids were shown to be inert, is the best anti acid materials. At room temperature, alkali and salt on quartz glass corrosion degree is minimal.

Transparent Narrow Neck Quartz Glass Flask for Laboratory is a new type high purity and high temperature-proof quartz glass material, the strong points are:

1.low thermal conductivity,

2.small expansion coefficient,

3.high temperature proof,

4.excellent thermo stability and cost lowerthan other quartz glass.

5.It has been widely used as long nozzle and immersion nozzlebrick for the continuously flood steel,

6.flood gate brick and flood gate brickand flood channel for the float glass production, material bowl and material tubefor the ware glass kiln,

7.crucible for melting special glass, quartz glassceramics rollers for the horizontal glass toughened furnace, oxygen furnace brickfor aluminium production in the field of metallurgy,

8.chemical industry, buildingmaterial, national defense and science research
