The sterile
filter does not sterilize your final product. It is just a
filter the is sterilized for filtering. Though it has been said that some laboratories use
those
filters for filtering bacteria out of medicines. That bacteria are too large to get through the pores of those
filters, but viruses are smaller and they can pass through. But it is rare to have a virus in such a solution.
If you desire to sterilize your final product and it is highly recommend, Bake it for 250 degrees for 15 min then let cool and repeat 2 more times. 250 degrees is not enough to melt the stopper. (Some advocate putting a pin in the stopper to let air escape, but being careful not to stick the pin in so far that your liquid spurts out as it heats.) This process is not to evaporate alcohol but heating and cooling 3 times is to kill bacteria. The boiling point for BA is over 400f, so your right, baking wont remove it. Also keep in mind that the BA(ie magic solution) is what allows us to suspend 75mg+ per ML and without it we risk having the tren/AAS precipitate and sit on the bottom of the vial.
