Amber Topacio glass bottle 20 ml propolis DIN18 no cap - Pack of 135 units

If you produce propolis tincture in compact format or work with samples and single-doses, buying bottles one by one stops making sense — every order adds weight, time and cost. This professional format brings 135 amber Topacio 20 ml glass bottles with DIN 18 neck, ready to fill tinctures, oils or extracts in a single delivery. The same bottle we sell per unit (ref. TOP20MLDIN18), in a full case for craft labs and compounding pharmacies.

The amber glass shields the active compounds of propolis (flavonoids, phenolic acids, CAPE) from visible and UV light, slowing natural oxidation during storage. The standard DIN 18 neck is the classic pharmaceutical mouth for dropper bottles, compatible with any DIN 18 dropper cap with pipette and tamper-evident seal.

The 20 ml capacity is the compact format ideal for samples, single-doses or occasional-use tinctures: typical dose 15 drops/day, ~3 weeks autonomy per bottle. Also useful for pure essential oils, hydroalcoholic extracts or trial presentations before moving to the 30 ml format.

⚠ Dropper cap NOT included. Bottles come only with the DIN 18 neck exposed. To bottle tincture or extract you will also need 135 DIN 18 dropper caps (ref. TAPONDIN18), sold separately, and optionally DIN 18 dropper pipettes as spare parts if you reuse bottles.

Who this pack is for: beekeepers producing propolis tincture in sample or single-dose format, herbalists, craft labs and compounding pharmacies that already manage their own dropper cap supply. If you only need a few separate bottles, order the single unit instead.
