You have never had an issue with your vials coming out wet from washing before you put them in? If that's the case I'm assuming you're using a autoclave with a drying function and not any other kind of eating element such as a household oven or a lab oven because 99% of people will tell you unless sterilizing it at 400° for 2 hours which is way too long considering it is only called for $350° f 45 minutes but if you do it like that 99% of people will tell you the vials will come out still wet. Which is why some people dip them in alcohol personally I spray the inside with a mist of alcohol so that it will dry in the 45 minutes that it's in the oven and the extra 20 minutes or more that it takes to cool down
