Details

This high-quality Spectrum Tube effectively demonstrates the spectral lines of pure water vapor when placed in a spectrum tube power supply (not included). It is designed for use with power supplies capable of holding 26cm spectrum tubes (Eisco p/n ESRPH1197B). The 26cm long tube is made of durable, transparent soda glass and features a large 10cm capillary in the center for greater viewing area. For best performance and longest life, the spectrum tube should be operated in 30 seconds on / 30 seconds off time intervals. Includes instructions.

NOTE: For intermittent use only, not to be used as a lamp source. 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, the useful life - or time it takes to detect contamination with the usual measuring equipment - is very long.

..I contacted Geyer via email. I had an email back within minutes!.. A back and forth via email sometimes takes days with other companies and customer service doesn’t happen like this very often. When it does, it’s much appreciated. Brett at Geyer was very polite and accommodating!

The customer service rep went as far as to reach out to the manufacturer of a product to answer my question, and then provided pictures. She really went above and beyond and answered the question thoroughly and gave me exactly the information I was looking for. This entire process was also extremely fast.

I called to ask how to submit a Tax Exempt Certificate for my library and spoke to a real person, no automation or asking me to press a number. He was friendly, helpful and got our Tax Exempt status established immediately.

...I don't think I've ever experienced that level of customer service before, and taking it into consideration along with the quality of their products, I would absolutely recommend Geyer to fellow teachers.
