The tetra will remove some nasty poly's, but if eudragit is present, there is no way around doing some extra fancy footwork to bring back the goodz gaak-free.
UncleFesters KOH method in the "Deconstructionist Thought" thread or EvilScripter's Best Extraction thread.
Prepuce worked very hard as well on helping develop the latter method!

It's recommended to stop now and do either of the above
But if that isn't an option and SWIM wishes to proceed...this is what Ibee can offer to alleviate most but not all gaaks.
If it's not known if eudragit is present(usually isn't known until it's exposed), pass all the meoh extracted goodz through a fine sieve strainer after drying and scraping up! Recrush what won't pass through the strainer(mortar&pestal) then pass.
It needs to bee fine powder to expose all the polys to the tetra.
Do a tetra wash with 3 times the amount of pillmass, volume-wise. If drypillmass equals 40grams...you'll need 160ml tetra for the wash.
Add tetra to Pillmass and stir thoroughly let sit 30 seconds....stir again...get funnel setup with one single coffee filter lined in the basket.
Pour the tetra/pillmass into funnel and filter off tetra.
Spray down the inside of the filter with tetra(spraytube provided with cans)so all pillmass is on the bottom.
Take filter/Pillmass out of funnel and Squeeze off excess tetra carefully.
Open filter and break up the pillmass over plate and spread pillmass out to dry.
When completely dry...no tetra smell will be present.
Pour Dried pillmass into tall jar with headroom to allow 10 times the volume of meoh...ie...40g pillmass=440ml meoh.
Add alcohol and stir!
Let settle til clear! 3-4hours
Pull and put through fine filtration(charminplugged filterlined funnel) and collect and evap at roomtemp.
Repeat alky pulls until yield is close to expected.
If eudragit is present in this batch...it will make post-rxn work-up a bitch....it will also cut intial final yield by 50% for about 3 days until the eudragit falls out. The rest can be pulled after that time.
It's best to steamdistill in cases such as that to get higher yields and cleaner end-result.
It will teach what to avoid in the future.
And again...The other better option is to take what's on hand now and do either UF's or EvilS's method on it.
That way eudragit is sidestepped...present or not!
Good Luck!
Keep us posted!
