I premeasured powdered formula in what I thought was dried bottles and left it in there overnight and the next day when I added water and gave it to the baby he spit it back out. I then smelled the milk it had a sour smell. I guess some moisture must have gotten into the bottle. Either way I don't recommend premeasuring powder formula in the bottle. The formula i used was Similac.
Re: FYI-Don't premeasure formula in bottle
Do you have any formula dispensers? BRU has a few kinds, you can get them at Target too.
You are always supposed to add water first, then the formula since the formula thickens the water and so a 3oz bottle ends up being more than three ounces when mixed together. If you add the powder first, you won't have the correct amount of water.

my friend who also formula feeds, premeasures the preboiled water into the bottles and leaves them out on the counter, and then uses a formula dispenser that can later be a snack carrier, available at BRU or Target, athen it is easier she said at night to do feedings as well and does not have to heat the formula after as it is already room temperature.
you are also not getting the right ratio of water and formula by putting the powder in first. I ould not do this anymore.
