I have 2 sep. funnels and im loving them.
They really work good.
Also they are not so expensive if buying ebay china stuff.
But the prizes goes up dramatically when sizes get over 1 liter.
I have one 250ml and one 1000ml.
Get the ones with teflon or PTFE stopcock as the glass stopcock ones needs to be lubricated.
The PTFE ones just work right out of the box, no lubrication needed.
I would also recommend getting a cheap vacuum filtration set.
I have this set with a 100mm buchner funnel, filter papers, heavy wall filtration flask with vacuum outlet, the rubber stopper and a hand vacuum pump with meter on.
It was not so expensive to buy and it has worked really good.
When filtrating gooey stuff it is just fantastic.
I was warned that the plastic hand vacuum pumps usually breaks down after a while but so far it is working great.
Even if the hand pump do break down it will be easy getting a small electrical pump for replacement.
The sep. funnel and the vacuum filtration set is the 2 things i certainly don't want to be without, they make everything so much easier.

Growing active and sacred plants and mushrooms is fun.
Chemistry and technology is fun.
Anger, violence and restricting rules are NO fun...
