The Twin Quartz Tube has smooth and colourless surface. Properties: high purity (SiO2 > 99.99%), abrasion resistance (any acid), fire resistance (softening point 1700 centigrade), low coefficient of thermal expansion (5.5 x 10-7/centigrade, heat the tube to around 1100 centigrade, then place it in the normal water, the tube won't crack); the surface can be done with gold plating. Sizes: single outer diameter x double outer diameter (mm): 8 x 17, 11 x 23, 15 x 33, length (mm): 400-4000.
