These are the same rings I used in the pharmaceutical labs in which I worked. I used them to hold separatory funnels for doing extractions. Buy some, you won't be disappointed.

these aren't to the exact size, so careful, i am just not returning because its a hassle, but for me i needed 65mm not 68mm, so it's useless to me.

This support ring is of high quality,it's longer and the metal rod used to produce it was also thicker compared to the one that came from a lab stand kit i've bought a couple years ago.
