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.

Great price for a great product
Color: Coal Black
Excellent quality and great price to boot. Easy to assemble and folds up easily to be stored. We are using it as a privacy screen when we have company that needs to sleep on the couch and also to block off a hallway leading to a guest suite. It looks great and is as described in the ad

No.
Color: Coal Black, Color: Coal Black
This was horribly made and a nightmare to put together. You have to basically bend the bars to get the coverings attached. The sizes don't match. The stickers that label the parts are impossible to remove and if you do get them off theres a lot of residue left behind. On top of that once it was put together I noticed theres a big dirty foot print on it which is definitely not mine.

You have to add weight to it
Color: Coal Black
It does its job and it was easy to put together but it's a little on the flimsy side and it will easily be knocked down. So you're going to have to figure out a way to make the legs heavier? I used cinder blocks, single cinder blocks and it works just fine. Just know that it will knock over super easy

I have 2!
Color: Coal Black
My office is in my loft. But there are things along the wall I don’t want to look at. These work great. Hides what I don’t want to see & is a classy look in the room. Sturdy, easy to assemble, well made.
