FAQ

Can these bottles be used with solvents or chemicals other than water-based solutions?

The bottles are made from a high‑grade, food‑safe polymer that is compatible with most water‑based liquids, mild acids, and alcohol‑based solutions such as essential oils. However, they are not recommended for strong solvents like acetone, chloroform, or concentrated acids, which can degrade the plastic over time. For aggressive chemicals, we suggest using containers specifically rated for chemical resistance. Always test a small amount first if you are unsure about compatibility. Storing the bottles away from direct sunlight will also help preserve the material’s integrity over prolonged use.

How do I clean and sterilize the dropper bottles for reuse?

To clean the bottles, first rinse them with warm water to remove any residue. Use a mild, non‑abrasive soap and gently scrub the interior with a soft brush or cotton swab, paying special attention to the dropper tip and the neck threads. Rinse thoroughly to eliminate soap traces. For sterilization, place the bottles and caps in a dishwasher’s top rack or immerse them in a 70 °C water bath for 10 minutes. Allow them to air‑dry completely before refilling. Avoid using harsh chemicals such as bleach, as they may damage the polymer and affect future dosing accuracy.

Is the funnel included compatible with other bottle sizes?

The funnel is designed with a wide mouth that fits the 15 ml bottle neck perfectly, but its dimensions also accommodate standard 10‑15 ml laboratory bottles with similar thread sizes. It will not seal tightly on significantly larger containers, so for bottles above 20 ml a separate funnel is recommended. The transparent plastic construction allows you to see the liquid level while pouring, reducing the chance of over‑filling. If you need a funnel for a different size, Notoke offers a range of compatible accessories.

Can I use these bottles for storing medication drops for children?

Yes, the bottles are suitable for storing pediatric medication drops, provided the liquid is compatible with the polymer material. The clear white design makes it easy to monitor the remaining volume, and the leak‑proof cap prevents accidental spills that could be hazardous to children. Always label the bottle clearly with the medication name and dosage instructions, and keep it out of reach of unsupervised children. Consult your pharmacist if you have any concerns about chemical compatibility. Store the bottle upright and avoid exposing it to extreme temperatures to maintain medication stability.
