Question 1

Can the black rubber bulb soften over time?

Accepted Answer

Yes, this is one of the limitations of pipette droppers. Certain strong solvents and essential oils — particularly citrus, menthol-rich, or high-monoterpene varieties — can over the long term swell, soften, or discolour the rubber bulb. If you intend to store such material long-term, it is advisable to fit an aluminium cap to the storage bottle and re-attach the pipette only for the duration of dispensing. For shorter periods (weekly or monthly use), the black rubber bulb is suitable even with strong essential oils.

Question 2

Exactly how many drops does a single squeeze dispense?

Accepted Answer

A single squeeze of the pipette draws up roughly 0.03–0.05 ml of liquid, which at essential-oil viscosity typically corresponds to 1–2 drops. With a light press on the side of the bulb, however, you can also dispense drop-by-drop: the smaller the squeeze, the more precise the dosing. For precise recipe compounding it is worth checking the first few drops on a scale, since drop size varies with viscosity. This is particularly important for cosmetic formulations where active-ingredient concentration is critical.

Question 3

Can the pipette be washed in a dishwasher?

Accepted Answer

We do not recommend the dishwasher for either the glass bottle or the pipette cap. The painted layer on the glass may fade in high temperatures and aggressive detergents, and the rubber bulb may be permanently damaged by detergent and heat. For cleaning, unscrew the pipette, draw warm soapy water through it a few times, then rinse clean. For stubborn fragrance residue, a few millilitres of isopropyl alcohol helps — followed by another rinse with water and complete drying before reassembly.
