boil some water in a large bowl. put a cup in the bowl, dont let water get inside bowl. put the vial in the cup. cover the entire thing with a thick clothAlright, educate me on this.
Do the vials need to be warmed before filtering? If so, in the oven.. won't this damage the rubber stopper?
Alternately, I could use the 0.22mm disposable filter for each pin?
