(Part 2) Best lab funnels according to redditors

Those.... don't look like powder funnels. The "drip tip" is the red flag; none of those are going to have particularly wide stems and the long stem is just going to get clogged with powder.

If you're on a budget I'd look for a plastic funnel with a stem OD <24 mm like this one or this one. If you're willing to fork over a little more cash and get a glass one there are nice 24/40 joint funnels like this small one or this huge one.

A glass funnel like this to hold the paper

plus a vacuum flask

or a 2-Neck flask

to hold the coffee and let the displaced air escape. It wouldn't work as nicely as a chemex but if you like the look of labware in your kitchen go for it.

Note: I didn't take the time to find the right size funnel and you would want a bored rubber/cork stopper to put on the funnel.

here's 2000ML funnel I just found on amazon:

a bit pricey, but the higher in volume you get, the more expensive..
