when pulling out the naphtha

[shago]

If I do 3 naphtha pulls in the A/B extraction. Should I put the 3 extractions in the same baking dish to let it evaporate? or put it in 3 different containers and then freeze?

Do the 3, and combine them, let that evaporate until it's more viscous (probably about 1/2 original volume) then slap that in the freezer. Preferably using a pyrex baking dish which has a large surface area, and a lid to keep out Naptha fumes from the fridge and water from getting in.

I was thinking to use test tubes for freeze precipitation or it's better to use baking dishes?

it may be difficult to get the crystals out if you do it in a test tube..but you may be able to do it
