Needed these to make another tube furnace for the lab. I was a bit skeptical as I became aware of the country of origin but was pleasantly surprised to find 5 tubes at precision length, consistent I.D. and O.D., and the tubes were packaged in styrene with small cardboard separators. I'll need more in the future of various diameters and will elect to use this supplier.

No matter what you use these for as far as quartz tubing goes they are the best quality you could find. I’ve purchased these 3 times already and will continue to do so as they are needed

After using these tubes for some high heat experiments, I can say im amazed at what they can take. I was able to form one into a test tube using an oxy acetylene flame, while white hot, dunked it into ice water. No breaks, cracks or marks. They are great for decomposition reactions.
