how to prepare protein sample, if I want to load exact amount on SDS-PAGE

Hello Guys I have a trivial query, I have a protein stock 1000 µg per ml. Now I would like to load on each well 0.25, 0.5, 1, 2, 4, 8, 16 and 32 µgs. For 0.25 µg, 0.25 µl from stock + 0.25 µl 2x sample buffer , total 0.5 µl load on first lane. If I want to load higher amount like 16 µg and 32 µgs
