Addition funnel frustration
I've been having a very painful time getting consistent drop rates from my addition funnel, it has a glass stopcock and seems to be very prone to
freezing up but also it's extemely difficult to get it set to the desired rate.
Is there any trick to it? lubricant or similar to deal with the lockup and make the action of the stopcock more smooth?

Are you not greasing it?

Sounds like that would be the problem, is silicone grease a suitable choice and are there limitations I should be aware of?
Cheers!

Silicone grease is fine. Don’t use too much, and try to avoid getting it into the hole in the stopcock. It’s impossible to avoid a little grease
contamination in your material whenever you use a greased glass stopcock though. Because of that I try to avoid glass ones whenever possible, and
greatly prefer the PTFE variety since they don’t freeze and don’t require grease.
