Silicone Grease

[nkk]

I use Dow Corning High Vacuum Silicone grease which has no additives. It is very thick and we use it to seal stopcock and other glass joints for lab equipment. It is available in 150 gram tubes at roughly 32-cents per gram. The tubes are relatively large and I dare say that you would never run out unless you repair pens for a living.

 

+1. I get mine from Fisher Scientific for the lab (and they get it from somewhere...I do not think they actually make it, just rebrand and sell it). Either way, this stuff is chemical lab pure, so there are no contaminants. It works very well.

I think a lot of us use dow corning (or fisherbrand) because that's what's already at hand in the drawer in the lab.

:embarrassed_smile:

That's where I get mine...

"Darling, wherever do those non-scientists get their talc, stopcock grease, transfer pipettes and syringes??? Good heavens, they don't even have access to a decade timer or a variac!"
