I have try cyb's max ion tek but i always have a small amount of naphta in my vessel. I'm not able to pull all the naphta out with my turkey baster. How can i extract all this stuff?

I have a separatory funnel, can i filter the basifyed solution to remove the bark and after put it in the funnel?

Or maybe someone have a tip to use turkey baster efficiently.

Just keep doing pulls, adding fresh naphtha for each, until nothing comes out. Then you never have to worry about getting every drop of naphtha out.

Or, using the syringe/baster/pipette, suck up the very top layer, including some basified mix if necessary, and let it separate inside the instrument. Expel the basified mix out the bottom, plus a drop or two of naphtha to be sure to get everything out, then decant. You can also be less careful and just put it into a thinner container to separate and be decanted again.

Ok perfect, thanks for advices

Here's a quick tip.
Invest in a lab grade pipette, I bought a 10ml glass pippete + it's rubber bulb for less than 12 bucks online, it will greatly simplify the pulling process, if you suck some of the basified mix you can easily get rid of it by gently releasing the pippete against a corner of the precipitation dish, then slightly tilt the dish and the solvent will run down to the other side leaving the mix exposed, then simply wipe it off.

Practice and patience padawan. Practice and patience and a steady hand.

Thanks all. I will maybe buy a better pipette and continu practice my hand. ^-^

My first try with cyb's tek gave me 550mg from 50g of MHRB.

Overall i think my technic is not so bad.
