Hello

Because I have a small freezer for now, can i put in two dishes, inserted one into the other?
reduced air flow matters?

Not completely sure what you mean but what's more important is how cold your freezer gets (colder = better) and how saturated your solvent is.

You could combine the two dishes of solvent into one and pre evap some (until cloudy) then freeze.

Good luck

You don't need space for pre evap. You just let the solvent evaporate (fan can make the process quicker) so the solvent is more saturated leading to more product crashing. (Good thing)

If your solvent isn't saturated enough. You might not get anything to form.
So if you haven't done so I recommend pre-evaping.

Also a closed container is by far better. No water going into the solvent and you don't stink up your freezer.

Hmmm, i'm not sure if you did understand the process (correct me if i'm wrong).
You have 2 solutions for cristalizing :
1- you evap outside until no more NPS
2- You freeze precipitate = you seal the container to avoid evaporation in the freezer. And as Boogerz said, you can pre-evap = you evap a part of the NPS before to put your sealed container in the freezer

always I put into the freezer, and it always work (from 50g MHRB i can make somethig about 0.5g, only one extraction with 200ml Heptane at once)

what is point of pre evap ? more product out?

always afraid to evaporate, I live a block and a weak air circulation is here. You know, poisoning or something


Edit:
it make a differences if i add 200ml heptane at once and shake something about 10 times, between adding 50ml x 4times?

Step Six: Adding the Non-Polar Solvent
1.Measure out 50ml of naphtha (lighter fluid) and pour into the bottle.
2.Lightly shake and roll the mixture in a 'figure of 8' fashion (or like peddling a bike) for 20-30 seconds.(The idea is for the naphtha to 'touch' every part of the base mix)
3.Unscrew the cap momentarily to release any pressure build-up then tighten again.
4.Place back in a heat bath. (Heated pulls draw more product)
5.Leave for a while until the naphtha separates again. (edit: This has been reported to take an hour or so the first time (occasionally))
6.REPEAT THIS four times (shake/separate) to thoroughly mix them together. This should take around 45 mins.

i would reoommend to evap for a while on those pyrex and then use 2 mason jars, mason jars need less space on the freezer and have a lid that will prevent the freezer to be contaminated.

other thing you can do is place 1 pyrex on the freezer while evaporating the other outside, when the first one has precipitated then you place 2 second one on the freezer,
