Filling a dropper bottle is simple, but a few details decide whether the result is clean, leak-free and easy to dose. This guide covers the steps for glass dropper bottles with an assembled dropper (teat, collar and pipette), such as DIN18 (GL18) bottles, and the mistakes that cause most problems. Before you start Bottle and…
Introduction A dropper bottle dispenses small amounts of liquid and is used for essential oils, cosmetic serums, CBD oils, tinctures and similar products. Capacity ranges from a few millilitres to 100 ml, depending on the bottle. This article explains which sizes are common, how to check the real capacity of a bottle and what to…
Introduction Dropper bottles are used to store and dispense small volumes of liquid, for example essential oils, tinctures, serums and pharmaceutical drops. The bottle is usually made of glass or plastic, and metal and silicone appear in some designs. A dropper is also an assembly of several parts, each made of its own material. This…
Introduction Dropper bottles store and dispense small amounts of liquid. They are used for essential oils, tinctures, cosmetic serums, oral drops and other liquids that are applied by the drop.

Short answer Standard dropper teats are not designed for contact with acetone. Acetone is a strong solvent, and many common elastomers swell, soften, harden or crack when exposed to it. The most reliable prevention is to choose a compatible material and to test it with your own liquid. Coatings and handling tricks are only a…
Introduction Hydrogen peroxide is a strong oxidiser. Elastomer teats that are in prolonged contact with it, or with its vapour, can harden, crack, swell or turn sticky. This article explains what drives that damage and what you can do to limit it. Why hydrogen peroxide damages teats Oxidisers attack the polymer chains in many elastomers….
Short answer A used dropper teat is a small elastomer part and is normally not accepted in kerbside recycling. In most cases it goes into general (residual) waste. Rules differ between countries and municipalities, so check your local waste guidelines. Before you throw it away Empty the dropper: use up the contents where possible. Do…
Why teat cleaning matters The teat is the part of a pipette dropper that you squeeze to draw liquid into the glass pipette. It is in contact with the pipette and often with the contents, so residue on it can affect the next fill. This guide covers how to clean teats for DIN18 (GL18) droppers…
Short answer Sometimes. Whether a teat can be sterilised depends on its material, the method used and how many times the process is repeated. Rubber and elastomer teats differ in how well they tolerate heat, steam and chemicals, so there is no single method that suits every teat. The material specification or the supplier’s guidance…
Introduction A glass pipette for droppers and a graduated cylinder both handle liquids, but they are designed for different jobs. The pipette is part of a dispensing closure that takes liquid from a bottle and releases it in drops or small doses. The cylinder is a stand-alone vessel for measuring a volume.
