Need Ideas for a crap trap
Hey forum, Im looking for ideas on how to build a crap trap for putting between my filter and my vacuum pump. I think I can make a basic one using an
old bong of all things, but that wont be a permanent solution. Is there instructions for how I would do that already on these forums? Anyone have
experience building one?

My first worry was about letting liquids get into my vac pump, so used an old de-calcifier thing in the build of the new fume hood.
The very first thing i used it for was to vacuum filter something in acetone, so the clear plastic part isn't clear anymore due to the acetone fumes.

It depends upon the crap !
In general you need to filter out particles, dust, water, solvents and, corrosive vapours.
Wash bottles (e.g. https://www.alibaba.com/product-detail/Gas-Washing-Bottle-Dr... )
or something similar are required,
(Mine are just 600 ml aluminium bicycling water bottles (£1 each) with glass tubing araldited through the stopper(s)
to trap bulk liquids
to trap particles and dust I use stainless steel wool 'wetted' with vacuum pump oil
for solvent vapours, dry ice/acetone or similar is required, I can't afford that,
for corrosive fumes you need to bubble through the 'antidote' for the particular vapour,
