Measure out concentrated liquids without making a mess!

I like to buy car care products in bulk. Their shelf lives are usually years and I know I’m going to use them eventually. The only downside is getting concentrated products from the big container into a smaller, usable container. I always spill some, which defeats the whole purpose of saving money! That was until I got the Pro Blend Bottle Proportioner.

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!


The Bottle Proportioner Combo comes with two different sizes: gallon and quart. The Gallon Pro Blend has a 38 mm cap with a 12” tube. The Quart Pro Blend has a 28 mm cap with a 9 ½” tube. The tubes can be cut to size if necessary. Both fill cups hold up to 3 ounces.

If diluting products has got you all wet, get the Pro Blend Bottle Proportioner. It makes the process of measuring out concentrates neat and easy so the only one covered in car care products is your car!


Note:The Bottle Proportioner is intended for low viscocity (thin) liquids.
