first time tek'er without a good freezer

[jmurda]

here's the situation, SWIM has access to all nessacary components to preform Nomans tek with 250g MHRB. SWIM has access to a freezer but only for short periods of time. SWIM doubts whether the freezer is even cold enough to parcipitate out any crystals.

So... evaporation seems like the way to go.

after reading :: Freezing vs Evaporating - FAQ - All your basic questions and answers - Welcome to the DMT-Nexus

SWIM has a vague idea of the differences but the only post there that focused on evaporation mentioned a waxy result rather than white crystal.

Can anyone here elaborate on the differences and how evaporation can be used if using vm+p naptha.

SWIM will test the naptha once acquired in order to see if it leaves any residue. If it does not, will the evaporated product be less "waxy"?

thanks

Just do an evap rather than a freeze precip and then recrystalize.
It might take a few more passes, but you're pulling the same amount of spice either way.

sounds like a plan.


after evap, one should expect a larger yeild before recrystalization in compaison to freeze precip..? SWIM is going to recrystalize anyways for the most pure product.

Does going evap > recrystal have an effect on purity as opposed to freeze > recrystal or just freeze?

Thanks

Not really the only difference being that if you freeze precipitate first you get rid of a lot of the impurities right away. Its just as easy to evaporate your whole solution and recrystallize it using smaller volumes of liquid etc.
