i would love for someone more experienced to tell me if this is improper technique or not but what i meant was
you get a big sturdy thick ziplock baggie without any holes (besides the one you will create in a minute). one that is big enough to hold alll the mixture easily without it leaking.
get some latex/medical/dish cleaning gloves, or at the very least have someplace to wash your hands or any spills nearby.
pour your mixture into the baggie.
let it fully separate, until there are no emulsions, if the layers already separated in a jar previously you may still have to wait a bit since pouring the contents into the baggie will naturally mix it back up, depending on how precise and patient you are with pouring
when there are two distinct layers you carefully hold the bag at one top corner with one hand, and with another and some scissors you carefully snip a very tiny hole in the bottom angled corner and let it start to drain (of course, into whatever containers you want each layer to pour into)
you can make the hole bigger or smaller depending on how fast you want it to drain out, however, the tinier the hole the easier it will be
to make a precise separation.
at this point you have two different containers (normally two jars/flasks or one jar flask/one evaporating dish ((pyrex, usefully))
and you let the bottom layer pour into one and then quickly switch to the other letting a little bit of the top layer go with if necessary for a clean separation. if it helps you can use your gloved hands to pinch the tiny hole at the time when it gets close to the division (this helps especially in a little emulsion still needs to settle)
and well, there you go...
the only thing is i am unaware if there are any safety concerns for the use of plastic like this. because for example some solvents like acetone for example can dissolve certain plastics. (which you might know if you ever tried cleaning a plastic (not glass

)waterpipe out with acetone instead of isopropyl or boiling water.
hope this helps.
to err on the side of safety glass is always the way to go if you can find something that might work. dmt polyplastic whatever won't do anyone any good
