SPECTRUM TUBE IODINE VAPOR ,Each

Details

Here is the corrected text: • High-quality design for a greater viewing area • Effectively demonstrates the spectral lines of pure substances • For use with spectrum tube power supply (includes 1 Spectrum Tube) These high-quality spectrum tubes are designed for power supplies holding 26cm spectrum tubes and feature a large 10cm capillary in the center for a greater viewing area. They are designed for operation intervals of 30 seconds, and should be used for 30 seconds on / 30 seconds off. The tubes effectively demonstrate the spectral lines of pure substances. Tubes require a spectrum tube power supply. For intermittent use only; not to be used as a lamp source. NOTE: The expected life of spectrum tubes will vary depending on the gas they contain. If the tubes are used as recommended and not allowed to overheat, their useful life – or the time it takes to detect contamination with usual measuring equipment – is very long.
