High Temperature Heating Quartz Glass Test Tube - 15-100mm (5 Pack) - Transparent Lab Glass Tube for Chemistry Experiments & Scientific Research

The mall specializes in producing and selling high-purity experimental products for "scientific research institutes, universities and other" scientific research institutions and laboratories. For experiments, we should buy high-cost and high-purity products instead of low-cost and low-purity products. We should buy according to the actual use. Although the purity of industrial products looks the same. We should avoid low purity industrial products entering the laboratory, which will affect the accuracy of experimental results. 1、10-75mm (5) in the option is equivalent to 5 quartz flat mouth round bottom tubes with a diameter of 10mm and a length of 75mm. Other specifications in the option also mean the same. 2、Characteristics of quartz test tube: it can be used below 1100 ° C for a long time and below 1450 ° C for a short time. The melting point temperature is close to 1730 ° C. 3、Good insulation, strong acid resistance (except hydrofluoric acid), visible light transmittance of more than 93% and ultraviolet spectral transmittance of more than 80%.
