Pro-Blend Bottle Proportioner Green | 1 Gallon 38/400Neck

These will fit any bottle with a 38/400 neck. This is a very common size for 1 gallon jugs.

This clever device saves you the trouble of trying to measure out concentrated products and pour them into another bottle. The Proportioner does it for you. Simply twist the Proportioner onto a bottle of your favorite product. Twist the black top to raise or lower the green regulator to the desired amount of liquid. Squeeze the bottle and watch the reservoir fill. Measurements in ounces and milliliters are marked on the side of the reservoir. Release the bottle and the liquid will drain down to the amount you selected. Flip the pop-top and pour the precisely measured liquid into another bottle. No dripping, spilling, or waste!
