More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the tube is made of glass having a linear coefficient of expansion not exceeding 5 x 10^-6 per Kelvin within a temperature range of 0°C to 300°C
This alternative covers laboratory glassware of other glass with specific thermal properties, which may apply if the fused quartz composition differs.
If the tube is not specifically of fused quartz or other fused silica
This residual heading covers other laboratory glassware not made of fused quartz or low-expansion glass.
