Dropper Bottles

Discover our Orion dropper bottle series, inspired by the very popular round-shaped Boston, with its short, curved shoulders. It’s designed so that the slope of the round shoulder allows products to easily slide out of the bottle when tipped. This makes it ideal for a wide variety of uses and compatibility with a large selection of closures. Each item has a DIN18 neck finish, except for the 200 ml which comes with a 24/410 thread. Dropper bottles are made to naturally protect your high-quality essential oils, homeopathic and skincare products, lotions, creams, gels, tinctures, serums and so much more.

Let’s talk about threads

...But what exactly are threads?

Simply put, threads are the protruding lines around the neck of the bottle. They ensure that the matching closure will have a tight fit to protect your natural products from being tampered with or from leakage. The thread size depends on the size of the bottle neck as well as our closures. Our bottles and jars and corresponding closures must have matching threads. If in doubt, it’s always advisable to contact our 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. Pipettes go hand in hand with the Orion dropper bottles up to 100 ml, featuring the DIN18 thread and a tamper-evident transfer ring. For pipettes, it’s 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 for 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 thread turns around the neck. Simply match the GPI or GCMI code listed in the product description to purchase the correct corresponding items.
* Please note that if a bottle has an additional ring on the neck, this may affect the choice of matching closure. For more details, please get in touch with your MIRON representative.

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