"fixing" my suspension

[vampire]

I've got a bottle of suspension (TNE) 100 mg ml in oil that got exposed to freezing temps (left outside) and now some of the crystals have come out of suspension - they're just floating around. Is there anything I can do to fix this?

Try warming it on the stove in a pan of water.

yes but put a pin in to allow air in while cooking

I've heard of others recommending this as well - I NEVER do it. I bake ALL my homemade gear for 20 min in a pre-heated oven at 250 F. Then let cool for 10 min, sitting on the grill of my downdraft fan that's turn on high. Then repeat 2 times.

My reasoning is that you can bake-out the BA. I want to keep in as much BA to prevent bacteria growth, which is why it's in there. I've never "broken" a vial from not venting a vial. But then again, I've only baked about 30 vials

If you have a bottle of "suspension" the crystals are not dissolved in the first place so you cant really make any crystal form by subjecting it to the cold.

However if you have an oil or Glycol based "solution" heating it would fix any crystals that may have formed in your vial as stated previously.

Thanks, I've had the same problem.

yep, baked it @ 250 degrees for 20 min, let cool for 10 min, repeated X2 - this did the trick, crystals are gone. Thanks for the advice guys
