Wanted: Small size ground glass joints

[themoch]

I need some small joint sizes, like in the range of 6-12 mm.

anybody know if these are out there, i'm sure in some scientific mag maybe.

I'm not going to grind my own as i'm looking for these in a production piece.

thanks in advance.

i just got home from winship and i think i spied some 10mm...

...here (http://www.winshipdesigns.com/home2/ws3/smartlist_59/ground_joints_simax.html) they are.

okay,

so now some questions

on a 14/23 what is the diameter that the male end tapers down to? also, what is the wall thickness on these things?

[Buckeye]

I've seen simax 7/25 and 10/18 which are the smallest I've found, the tapered end of a 14/23 is 12mm and 2mm wall thickness.

i just measured one and it appears to be 12mm at the small end of the 14/23. they're not precision calipers though so it could be off by a fraction. mathematically it's a 1/10 taper so with the 14/23 measurement we should have enough for some basic geometry if you need a precise answer. 11.7mm i think? the wall thickness varies from brand to brand.
