Chemical laboratory equipment high borosilicate glass test tube 30*200mm

Product Overview

Description

The temperature of hardening point is about 1730C, which can be made at 1100C for a long time With a maximum temperature of 1450 "C.The thermal shrinkage coefficient is very small, can be subjected to violent temperature change, quartz glass heated to about 1100C, put in room temperature water will not burst
In the purple inner line to the red inner line all spectral bands have good transmittance, visible light transmittance is more than 93%, especially in the ultraviolet spectrum, the maximum transmittance can reach more than 80%.
The resistance value of quartz glass is a good electrical insulation material, even at low temperature also has good electrical properties
