I have a 20ml sterile vial where i transfered all my gear from amps. Due to the fact that i have a small chunk of rubber on the bottom (luckily it's stuck so it doesn't move) that i got while pinning the stopper at an angle i check my vial VERY carefully under a light spot.
I'm wiping the stopper with a cotton ball soaked in alcohol and i noticed that strings/fibers remain on the stopper when alcohol dries out, i also spotted a string of cotton in my gear and i fished it out. Probably got pushed by the needle through the rubber stopper.
What should i use to vipe the vial top then?
Should i use sterile gauze pads soaked in alcohol? they look like this http://www.sensicare.ro/image-thumbnail-500x500-upl/uplphoto/-produse_662_17615.jpg
Presoaked Alcohol pads are pretty expensive locally : $5 10 pads.
