Product resistance as a function of dry layer thickness for 5% and 10% sucrose under same load condition (i.e., one shelf) with 2- and 4-mL fill volume. Closed and open triangles are for 4- and 2-mL fills, respectively, of 10% sucrose, and closed and open circles are for 4- and 2-mL fills, respectively, of 5% sucrose. The difference between the 4- and 2-mL data for 10% sucrose is just outside the usual 10–15% reproducibility and may not be significant
