You either weight it in a glove box, under dry nitrogen gas, if your that worry about it absorbing water. Or you weight it normally as the time taken to absorb water is a lot longer than the time it takes to weight it out.

It doesn't take on water all that quickly. Most of the bench grade stuff you get has traces of water in it anyway. If you were really keen to exclude moisture, you'd have to use a glove-box to transfer it between containers, but if you're just worried about the uptake of water spoiling your weight-measurements, it's unlikely to make a difference for most purposes.
