We offer a selection of high-quality pipette droppers. Often called eye droppers, they allow to dose a product drop by drop, applying it accurately in the amount and on the location required. A dropper also ensures that your product does not get contaminated during use. Indeed, only the drop will touch the specific body part (skin, mouth, etc.) concerned which leaves the pipette intact. A pipette dropper is generally made from three parts: a rubber bulb, a hole cap (the body) and the pipette.

All quantities are rounded to the number of pieces per safe packs.


Child-resistant packaging is created to prevent children from getting access to the contents of, e.g., medicine. Child-resistant closures have a special feature that provides a certain resistance when a child wants to open a particular product. It, therefore, reduces the risk of children consuming a substance that might be harmful to them.

Series II, III

The number in the series indicates the shape of the cap and the tamper-evident element of the dropper caps. For instance, II suggests that the closure has a tampered evident ring attached to the closure, and because the cap is made of only one material/mold, it has 4-6 ridges on the side. Series III has a thicker rim and features a more luxurious tampered evidence element. This series is made from multiple molds, which means that a different system of tempered proof is used consisting of retention fingers instead of ridges on the tear strip, making it less easy to manipulate.


Tamper-evident is designed as an integral safety band that offers protection against tampering. Upon first opening, the consumer automatically detaches the cap from its safety band; this happens because the band is attached to the bottle or jar around the closure perimeter.

Let’s talk about threads

...But what exactly are threads?

Simply put, threads are the protruding lines curved around the neck of the bottle. They ensure that the matching closure will have a tight fit to protect your natural ingredients from being tampered with or from leakage. The threads size depends on the size of the bottle neck as well as our range of closures. Our bottles and jars as well as the corresponding closures must have matching threads. If in doubt, it is always advisable to contact the sales department.

DIN168/GL18 (DIN18)

DIN is the industry standard for dropper bottles in Europe, and DIN18 is the German-based norm. It refers to the standard size of the neck, height, and diameter. With a DIN18 threaded closure, pipettes go hand in hand with the Orion dropper bottles up to 100ml (3 ½- oz), featuring the DIN18 thread and a tamper-evident transfer ring. For pipettes, it is important to note that the length of the glass cylinder also plays a crucial role in choosing the right combination.


GPI and GCMI are the US norm of neck finishes and are followed by two numbers written like this: 22/400*. The first number indicates the neck finish diameter and is measured across the outside of the bottle’s threads. The second number refers to the height and thread style. Meaning, the number of threads turns around the neck. Simply match the GPI or GCMI code listed in the product description to purchase the corresponding items.
* Please note that if a bottle has an additional ring in the neck, this may affect the choice of matching closure. For more details, please get in touch with your representative.

TPE and NBR bulbs

TPE (thermoplastic elastomer) is the standard bulb (material) most commonly used for alcohol-based and low acidity products that cannot damage the rubber bulb. The NBR (nitrile butadiene rubber) bulb is a specialized bulb for oil-based and high acidity liquids. If you are unsure of which bulb to choose for your product, it is best to contact our sales department for tips. If you are using tips that have not been tested and validated, we highly recommend that you always test their performance to ensure they produce reliable results in the long run.


PP is also known as polypropylene and falls under the plastic identification code number 5. The material is easily produced and has a high degree of purity. It comes with a range of benefits, so is it difficult to break, lightweight, easily and 100% recyclable. Due to its properties, PP is suitable for various applications, including food, cosmetic, and natural healing product packaging.

Conical or straight tip vs. bent or straight ball

Conical or straight is chosen when you need to move volume, e.g., 0.5 ml. Conical pipettes are especially useful when you apply your substance to a specific surface (precision work). Pipettes with a bent ball are the most widely sold, and for a reason, as they allow for dosing a product drop by drop. The size/shape of the surface determines the size of the drop that comes out. Liquid tends to stick to the element it comes out, and this creates a droplet. With the ball, you get an average dispensing volume per drop. Additionally, the advantage of a bent ball is that you can get the last bits out of your bottle just a little easier, because the bent ball allows you to get into the corner of the bottle neck when you carefully rotate the container.

At MIRON Violetglass we ensure that our closures always fit the corresponding bottles and jars. However, it can sometimes be a bit of a challenge to find the right closure which complements the needs of your natural ingredients. We are always happy to answer any questions you may have and to become a part of your products journey.
