Ipomoea- A/B -> FASI

[kerelsk]

Hi I recently made an Ipomoea tricolor extraction as such:

1. Pulverized & ground the seeds to a powder, added cool water that was previosly boiled to remove chlorine. Excess NaOH added with sufficient water to make a relatively thick soup.

2. Extract alks with limonene
3. Extract alk salts with vinegar
4. Evaporate vinegar to smaller volume, add Na2CO3 till no reaction. Dry completely to crust.
5. Pull freebase alk crust with iPrOH
6. Add FASI to iPrOH to precip alk salts
Now I'm left with some pretty xtals it looks like, suspended delicately in alcohol

Any ideas how I can isolate these babies? Feel like filtering with a coffee filter or cotton wouldn't suffice

Can I blot out the alcohol with paper maybe?
