The classic apothecary look of green glass became a defining visual element of pharmaceutical and perfumery production for good reason: its filtering range extends beyond amber into longer wavelengths, providing particular protection for citrus and terpene-rich essential oils against light degradation. This 255-piece pack of 5 ml bottles arrives without caps, allowing you to freely combine the bottles with the closure best suited to your recipe — aluminium cap, pipette dropper, child-resistant or tamper-evident cap.
What the 255-piece pack contains
The pack contains 255 green glass dropper bottles, each with a nominal fill capacity of 5 ml, supplied without caps. Each bottle is approximately 45 mm tall, with a diameter of about 22 mm, and an average empty weight of 24 g. The total gross weight of the pack is 6.171 kg. The neck is manufactured with a standard GL18 thread, making it compatible with the widely available 18 mm caps and droppers on the market.
Green glass and dual light filtration
Green glass not only blocks the ultraviolet range but also moderates the blue wavelengths of visible light — exactly the combination valued by makers working with citrus oils (bergamot, lemon, orange, grapefruit). Monoterpenes and terpene aldehydes that are sensitive to blue light oxidise more slowly, so the scent profile of the oils is preserved longer. Glass is chemically inert: it does not react with essential oils and contains no plasticisers.
Why it comes without a cap
The cap-free format is a deliberate choice: if you work on several recipes in parallel, it is worth ordering the bottles separately with your preferred closure. You can use the same bottle body for a perfume base with a pipette dropper and for a child-resistant formulation with a CR cap. Thanks to the standard 18 mm neck, you can freely combine components in your workshop.
Areas of use
- Small sample bottles for your own essential oil blends
- Dispensing vintage perfume bases and cologne samples
- Long-term storage of citrus and terpene-sensitive essences
- Trial batches of facial serum samples and skincare recipes
- Bottling your own cosmetic line in a DIY workshop
Cleaning and recycling
Before first use, wash the bottles with warm water and a mild detergent. Stubborn scent residues can be removed with a 70% alcohol rinse. Avoid the dishwasher, as the high temperature and harsh detergent can damage the glass surface and make subsequent labelling difficult. Green glass is fully recyclable.
