CASE STUDIES
Spectrum tubes have long been used in chemistry classrooms to teach atomic structure and emission spectra. However, legacy power supplies were outdated, unsafe, and inefficient — offering minimal protection around high-voltage terminals (up to 5000V) and relying on fragile glass tubes that degraded quickly. Educators needed a safer, more intuitive system with improved tube longevity, user control, and classroom durability.
Steiner Enterprises delivered a ground-up redesign that addressed safety, usability and product life. A patented spectrum tube cartridge system dramatically improved durability and reduced breakage. Safety was further enhanced with the use of magnet and reed switch integration, allowing power to flow only when the cartridge is properly installed. For even greater ease-of-use, Steiner also developed a rotating carousel version that enabled quick switching between tubes — a breakthrough for classroom speed and efficiency.
Extended tube life and reduced user handling errors
Magnetic reed switch disables high voltage unless the tube is fully seated
Simplifies switching tubes mid-lesson for seamless teaching flow
Clean enclosure design with printed labels and robust feel
Improved reliability and reduced glass failure rate lowered lifecycle cost
Leveraged both domestic and international supply chains with final assembly and safety testing in the USA
The reengineered Spectrum Tube Power Supply has become the new standard in classroom spectroscopy, delivering unmatched safety, longevity, and ease-of-use. Teachers benefit from faster setup, fewer broken tubes, and increased student engagement, while institutions benefit from reduced replacement costs.
