The pipette dropper is the classic solution for precise dosing: the glass pipette tube combined with a black rubber bulb gives you deliberate, drop-level control over how the contents are dispensed. This 156-piece pack of 20 ml bottles is particularly well suited to formulations where exact ratios are critical — such as essential oil synergies or active-ingredient serums.
What this 156-piece pack contains
156 amber 20 ml glass dropper bottles + 156 black pipette droppers (glass pipette tube + black rubber bulb + threaded closure cap). The bottles are approximately 75 mm tall with a 30 mm diameter. The neck uses a standard GL18 thread. The total package weight is approximately 0.47 kg, with an empty unit weight of around 3 g.
Amber glass and UV protection
Amber glass filters out the shorter wavelengths of visible light and most of the UV spectrum — the photocatalysts that trigger oxidation of volatile compounds and degradation of active ingredients. The pipette design also helps the user avoid unnecessarily opening the entire bottle, dispensing only the amount needed — further reducing oxygen and light exposure.
Black pipette dropper details
The dropper consists of a glass pipette tube, a black rubber bulb (silicone or nitrile) and a threaded closure cap. Squeezing and releasing the bulb draws liquid up into the pipette, with fine dosing controlled by gentle pressure on the rubber. The glass tube does not react with the more aggressive components of essential oils and lets you see the volume drawn up. The rubber bulb may occasionally need replacing — particularly with long-term use of strong essential oils.
Areas of use
- Drop-by-drop precise dosing of essential oil synergies
- Dispensing of active-ingredient face serums
- Tinctures and botanical concentrates
- Aromatherapy formulation work
- Private-label cosmetics in pipette-dropper format
Cleaning and maintenance
Clean the pipette in warm water with a neutral detergent. For strong scent residue, rinse with food-grade alcohol. Do not leave the rubber bulb in concentrated essential oils for extended periods, as it can swell over time. The glass and the pipette tube can be separated, so both can be thoroughly washed and recycled individually.
