Is this ok? (recrystallization)

[Just a Ride]

Swim is doing a recrystallization and put the shotglass in a ziplock bag. Is that ok? Swim's main concern is nathpa evaporating in his fridge / freezer.

as long as the bag is airtight it will be fine. Its probably worth getting yourseld a small container with a well fitting lid.

I just use tin foil as a lid...works fine...no smell, no evap

 

[Just a Ride]

haha when I read the first reply I decided to switch that out and put on a tinfoil lid. You guys for feedback!

Heres a 1g Re-x pic. In a drinks glass (used tin foil lid)
Dried with fan for 20 mins after the Nap is poured out (make sure you dry well)

I like the way it grows out along the 'tide line'...very light and fluffy...Yum!

I have one of these for re-xing, it works very well. I think its ~25ml or something, not that exact kind, but the same design from a different supplier.

You can also take a look at reagent jars which also have wide mouth gong lids. Take a bit of veggie/sunflower oil and smear it around the joint to get an airtight seal before putting it in the freezer to prevent naptha/heptane vapor leakage, or water vapor contamination/condensation.

They're pretty cheap if you look on ebay. :thumb_up:
