Kettle clamps

I made a kettle clamp from a sheet of brass (0.032" thick) using tin snips, a drill press and a Dremel tool. Thumb screws and knurled knobs are used to hold it together. I made the one on the right first, but didn't finish it yet.

I suggest to use two metal rings in addition to the clamps for to avoid the risk of breaking out of the glass.

Nice reactors. Thats about exactly what I am after. To sad its US-Ebay though......

edit: I just now recognize that there is one ring - why dont use two rings and spring supported screws? This would keep constant pressure over a wide temperature range on the seal without risking to break the glass. I have seen this otherwise and found the principle quite convincing.

Ever considered to shave your hands? ;)

The brass is resilient already so using springs wouldn't help much. Two rings might be better. It takes a while to make them. I have get another piece of brass, too.

Organikum, aren't these just Schott "Planschliff" reactors?

They should be commercialy available to the public (as anything of schott is), so I guess there should be some second hand floating around.



One shouldn't accept or resort to the mutilation of science to appease the mentally impaired.
