If you want a sprayer or lotion pump with a glass or plastic bottle, you've probably noticed that each sprayer or pump has a dip tube that runs all the way to the bottom of the bottle. Some of them bend slightly to reach the corners of the push-up, while some sit up straight and reach the very top of the push-up. What you might not know is that each of these sprayers has a dip tube length that's specifically measured to fit the bottle it's paired with.

    A dip tube is a hollow plastic tube, usually made of LDPE plastic, that connects to the bottom of the sprayer or pump mechanism to extend the pump's reach to the bottom of the bottle. The function of the dip tube is to draw the product contained in the bottle from the bottom of the bottle, passing the liquid or cream product through the actuator to the sprayer or pump mechanism and to the consumer's hand. Most dip tubes are custom-made to fit a specific sprayer or pump, and the diameter of the dip tube is usually related to the output of the sprayer or pump. That's why you'll often see thicker dip tubes attached to lotion pumps compared to thinner ones for sprayers.

    Because these pumps and sprayers are designed to fit a variety of bottles with different interior heights and capacities, manufacturers typically produce sprayers and pumps with "standard" dip tube lengths of 10 inches or longer.
