The Quart bottle can be used with all sprayers. It has 2 unique features that differentiate it from other quart bottles: The molded gradations on the side indicate the number of ounces and milliliters. It also has dilution ratio fill lines so you mix your concentrates properly. You will see lines on the quart marking ratios of 10:1, 5:1, 3:1, 2:1, and 1:1. Pour the water-based concentrate product to the ratio line of your choosing, and then fill with water to the "fill ring" line at the top.
