Product Details

Specifications

1.high SiO2 ( >99.998%)content
2.No lining, no bubble, no scratch in first grade quality
3.high temperature resistance

The advantage of quartz test tube

1.high temperature resistant,can work under 1200°C continuously,and in short time can even work under 1450°C.

2.The softening temperature is 1650°C,and the melting temperature is 1750-1800°C.

3.Corrosion resistant, Except hydroelectric acid, quartz test tube do not react with any acid and base

except hydroelectric acid.the stability is 30 times of the ceramic,and 150 times of stainless steel.

4.Excellent thermal shock stability

5.High transmission to 85%

6.Electric insulation ,it is 10000 times of usual glass
