hello, you seem to know a little about autoclaves. i bought one 8L autoclave and ultrasonic cleaner.
do i need the ultrasonic cleaner?

when im going to use the autoclave should i just clean it with alcohol then pour destilled water into the "tank" on the top?
and then start it?

also do you know if the vacuum removes "hairs" and stuff that is in the air that sometimes gets in the vials?

thanks
