The Spectrum Tube EHV Unit and Tube Support is used to excite gas molecules in spectrum tubes for experiments involving atomic spectra. It provides high voltage safely and can be adjusted for emission or absorption line observations.

The Spectrum Tube EHV Unit and Tube Support is a self-contained unit that can be powered by a 240V AC mains source specially designed for classroom settings. . It is equipped with a stainless steel rod and sliding clamp for supporting different lengths of Spectrum Discharge Tubes. The instrument also features a recessed high voltage terminal located on the top face, and a removable mains cable. This powerful tool provides precise and reliable results. 

Spectrum tubes are long, thin lamps filled with specific gases. When electricity is passed through them, known wavelengths of light are emitted, making them useful for optical experiments. The initial high voltage needed for conductivity is later maintained at a lower voltage, which is provided by the power supply.

Worth the purchase
Color: Orange & Blue Fumbler, Size: 3 x 8.5 x 9 inches (1 Pack)
Perfect for indoor use. My aggressive chewer loves this and has not destroyed it yet after 6 months. I recommend for indoor use as it causes NO damage or noise.

My lab loves t
Color: Orange & Blue Fumbler, Size: 3 x 8.5 x 9 inches (1 Pack)
This toy is my labs favorite toy. She’s obsessed and we were happy to find a toy she loves that can stay inside with us. The problem is how easily she tears it apart. We have to buy her a new one every month because when she bites into it it breaks down the foam inside, and from there she shreds the roping it’s covered in. We try to stop her, but with how often we play with it it’s inevitable. We have resigned ourselves to buying a new one once a month.

Not Chuck-It Durable
Color: Orange & Blue Squirrel, Size: 4.7 inches (1 Pack), Color: Orange & Blue Squirrel, Size: 4.7 inches (1 Pack)
Sadly only lasted an hour. My dog likes to pull apart toys over the course of a few months, with the exception of Chuck-It toys. They usually never get destroyed by him. I think its a good product but if you are looking for the durability like other toys from Chuck It - just wanted to share this is not the toy for you! Made him happy so not regretful of buying it, just wish it lasted longer. Here is him posing with it after he took bites of it like it was an apple.

Boredom breaker!
Color: Orange & Blue Squirrel, Size: 4.7 inches (1 Pack)
Chuckit is my go to for my 60 pound American fox hound! I had a fractured spine and needed something quickly to keep him distracted indoors while I was healing. I love that it was durable but still did not harm my hardwood floors or furniture! It arrived overnight! I highly recommend!
