Replacement 14MM (F) to 14MM (M) borosilicate glass chamber with handle.
Made in the USA with German glass by a family owned scientific glass shop.
After a decade of working with other companies to improve their products, it was high time to start developing my own. Tired of compromising designs, in 2019 I created the original ruby ball heater - and I've been improving it ever since. I have been an obsessive member of the community since 2013 and hope to finally share more concepts I've developed along the way.
