They stay sterile for 24 hours as long as you dont take the lid off. As soon as you take the lid off to get a bottle out you either need to take them all out and assemble them in which case they are still sterile for 24 hours or you need to re sterilise them all. I assemble once mine are sterilised and put them in the fridge so I know what has been sterilised and what hasnt.
i had an electric steam steriliser, which had a count down on the front of 3 hours to let you know when the bottles were sterile. I always made up my bottles straight after sterilising though always doing 4 at a time xx
