I want to clear up some misinformation in this post - you are partially correct in most of what you said.
*weather changes won't produce moisture in the vial unless you are letting it in. (I.E. sticking a needle through the septa while the stopper is swill wet after swabbing, or if you inject air into your vial when the humidity is high)
*I agree, the only way to get moisture out would be to heat it. But just think...water isn't the only thing that evaporates. Solvents, oil, everything can evaporate.
If you have water in your gear, you are doing something wrong with your injection technique/sterility measures or the lab you use is not operating properly.
**Just because there is alcohol in something does not mean bacteria can not grow.
--A certain % will prevent bacterial growth, and a certain % will KILL bacteria. 2% BA is not enough to kill "all bacteria" like you are saying.
Yeah, a bottle of rubbing alcohol will stay sterile even though you open it multiple times. Rubbing alcohol is 70%-99% isopropyl alcohol...and the oils we inject are anywhere from 0.9%-3%. No where near a bottle of rubbing alcohol, you just can't compare the two.
If all I had to do to sterilize gear was put some BA in it, then why the hell do so many people get infections? Most UGL's overdose their BA as a safety precaution to begin with...
Another thing is that bacteria DOES get into the bottle of rubbing alcohol. They just die when they come in contact with the alcohol, leaving their corpses to float in the alcohol (or dissolve...) for lack of a better way of putting it. Same thing with your oils - even if the alcohol content is high enough to kill bacteria that you let in, there is still remnants of the dead bacteria in your oil which can lead to PIP and other issues.
You won't be able to create enough pressure in the vial to crack it just by heating it within the range we need to evaporate water or put crashed gear back into solution. If you make a vial explode with heat, your hormone was damaged long before that could happen anyway.
(I'm not pick on you, I'm just clearing up misinformation so people don't end up with infections)

I agree and disagree on the venting post. Some gear gets cloudy from weather changes and produces moisture in the vial or moisture was already present in the vial. The only way to get moisture out is to heat it but it has to be vented to allow for the moisture to escape, if its not vented the moisture will not get out of the vial and the gear will clear up then cloud up again once the moisture turns from a vapor back into a liquid. There has to be a way for it to escape, this is why a lot of times when you heat gear to clear it and it clouds right back up shortly after, because the water didn't escape and is still in the vial. I have had gear that clouded up and I heated it only to have it cloud back up, and this was with venting but I didn't leave it on the heat long enough to get all the moisture out. You will see drops of water on and around the vent pin when you heat gear that has moisture in it. It take alittle bit of time but it will eventually all get out and the gear will clear up and stay clear and not have to be reheated. As far as bacteria getting in through the vent pin I understand where that is coming from but you have to understand that the gear has BA in it which is an antimicrobial meaning it kills all bacteria and prevents bacteria from growing in the vial. If you think about it a bottle of rubbing alcohol is opened and closed all the time and no bacteria gets in it when you take the whole cap off for minutes sometimes hours at a time, if you forget to put the cap back on, bacteria wont grow in anything with alcohol in it so the worry about bacteria getting in it is a valid worry but it isn't going to happen once the BA is in the gear. Its a good concern though but not going to happen. You can heat the gear with no vent pin but more than likely it will cloud back up shortly thereafter or you can vent it and get the moisture out and not have it cloud back up again. Another thing with not vening is you can run the possibility of cracking the vial if the pressure inside gets too great that it expands beyond the point where it needs to escape and cant, kinda like a car tire when its cold it looks low but after driving for awhile it heats up and the air inside expands and the tire looks fuller after driving.
Just a couple things to think about but in any case the gear is good clouded or not, just more watery clouded.
