The starsan bottle has two screw on lids, one over the main container, the other over a much smaller volume container. Both are connected by a small tube. You squeeze the big side until enough fluid is in the small side (it has marks for 1/4 and 1/2 oz) and then pour it out of the small container. Sonds like your bottle does not have this feature? (I would post a photo but #2 daughter appears to have filed our camera with my watch that #1 daughter filed somewhere a few years ago (yet to be found...))
