I've been emptying my packets over a piece of paper now, seems easier than trying to get it all out of the little packet into the little vial without spilling any.

Yes, I rinse in RO water after every use. And after filling with water and then powder I also rub the outside of the vial with a towel to be sure it is clean and no finger prints before inserting into the checker.

I cut the packets and make a crease in them, to funnel the powder. I also use the scissors tips to open up the ends inside to be sure no powder stays trapped in there. Then I just hold the vial at a 45 degree angle (easy to over spill powder if held straight up) and tap in the powder from the funnel crease in the packet.
