Ten Facts About Dropper Cap Assemblies To Sharpen Your Knowledge

dropper caps for wholesale glass dropper bottles

When you or your business is in need of wholesale glass dropper bottles, you probably don’t put much thought into the most important part of many products: the dropper cap assembly.

If you have ever used essential oils, CBD oil, or liquid medication, you’ll know that without the glass dropper, the liquid would not go to its intended place but would instead cause a mess. Valuable products would also be wasted due to the difficulty in pouring just the right amount from the bottle. Glass droppers help customers and those dispensing products to avoid the loss of valuable inventory.

What Are Dropper Cap Assemblies?

Dropper caps are made of three main parts: the rubber bulb, the plastic cap, and the glass pipette. Together, they form the cap of a glass bottle that’s meant to hold liquid. The rubber bulb is the “squeezable” part of the lid, the cap is simply the part that screws onto the bottle itself, and the pipette is simply the glass tube that is connected to the bottom of the cap and extends into the glass bottle. This assembly allows the user to safely remove liquid from the bottle and/or use just as much as is needed, one drop at a time.

The Physics of Dropper Caps

Dropper cap assemblies use the laws of physics to pull liquid from a glass bottle and into the glass tube. First, the user squeezes the rubber bulb on the lid. This forces out the air in the pipette and creates a vacuum. Then the pipette is inserted into the liquid and pressure is released from the cap. The vacuum needs to be filled, so the oil, medication, or other liquid has no choice but to go into the pipette.

The liquid then stays in the pipette until use. Anyone using a dropper cap assembly can then control the amount of product they squeeze out, thanks to the small hole at the end of the pipette. Once done, the extra liquid still in the pipette can simply be squeezed back into the bottle.

Types of Dropper Cap Assemblies

Regular dropper cap assemblies are simply that: a cap, a rubber bulb, and a pipette which may or may not be calibrated.

Another common type of dropper cap assembly is the “Euro” style. This style includes a dripper insert and is useful for bottles meant to hold fragrances, herbal extracts, and oils. It’s used for when precise measurements aren’t needed. The cap comes with the dripper already inside it and can be used by turning the bottle upside down and dripping a liquid one drop at a time.

Tamper-evident dropper caps have a ring that’s broken when the lid is unscrewed, and this allows you to easily see if a bottle has been opened before.

At last, CRC dropper caps are designed to be child-resistant.

Pipettes, and What They Do

The pipette is perhaps the most important part of a dropper cap assembly. They can be made of glass or even plastic, and they’re meant to draw liquid from a glass bottle and then dispense it. The great thing about pipettes is that they let you to dispense a liquid without spilling any extra drops or wasting any product.

To Contain, or To Dispense?

Pipettes are useful in a wide range of industries. Pipettes have two basic purposes. TC (To Contain) means a pipette is meant to hold a precise volume while TD (To Dispense) means that pipette has a design meant to squeeze out a very specific amount of liquid.  This is very useful for, say, dosing.

The Different Pipette Types

The regular type of pipette, or dropper cap, is simply meant to capture and dispense liquid. Etched pipettes have measurements on the pipette itself (typically in ml) and are meant for more specific jobs.

Uses Dropper Cap Assemblies

Dropper caps are useful for everything from pharmaceuticals to fragrances. CBD oil is dispensed using dropper caps and herbal remedies also make use of these products. Laboratories and schools can also find dropper caps with calibrated pipettes to be useful for their studies.

Different Styles and Colors

Since different colors of glass bottles exist, so do different colors and styles of dropper caps and pipettes. Amber pipettes can be ordered to match amber glass bottles, and caps with green pipettes can be ordered to match bottles of the same color. The most common type is flint, or clear, pipettes.

Dropper caps can also come in different colors (usually black or white) and as the regular Boston round cap or the Euro cap.

Different Bottles, Different Pipette Sizes

Pipettes also come in different sizes, ranging from 48mm to 100mm. You don’t want to have a pipette be so long that it touches the bottom of a glass jar, since glass is such a fragile material that easily breaks. It’s also a bad idea to have one be so short that it cannot reach the liquid on the bottom of a bottle.

Handy tables that are included on our product pages will help you find the right size.

Different Cap Materials

Plastics are most commonly used for dropper cap assemblies. Polypropylene and polyethylene are two common materials used to make up the caps, with Euro caps usually made of polypropylene. These materials don’t react with water, don’t easily crack and are durable, which help to prevent damage and leaks.
