This amber 100 ml bottle, supplied without a cap, is designed for makers who work with larger volumes of essential oil blends, massage oils, hydrosols, or tinctures, and who want to pair their bottles with their existing caps, droppers, or pumps. The cap-free format gives you full flexibility: combine aluminium caps, tamper-evident dropper caps, black pipettes, or childproof closures freely depending on the end product.
What you receive
One amber UV-blocking glass bottle with a nominal fill capacity of 100 ml. The price is for one bottle; for larger quantities, simply enter the number you need in the basket. The bottle is approximately 130 mm tall and 52 mm in diameter. The neck is a GL18 standard thread, so virtually any 18 mm closure on the market will screw on.
Amber glass and UV protection
Amber glass filters both the UV spectrum and the shorter wavelengths of visible light. These wavelengths trigger the oxidation of volatile compounds in essential oils, carrier oils, and tinctures. Stored in amber glass, your preparations retain their original scent profile, colour, and active ingredient content significantly longer. Glass is chemically inert: it does not react with oils and contains no plasticisers.
Why cap-free
If you already have a stock of caps, droppers, or pumps — or you would like to seal your finished product with a custom or branded closure — the cap-free bottle is the economical choice. The bottle neck is a standard GL18 thread, so aluminium caps, glass pipette droppers, childproof caps, and tamper-evident dropper caps will all screw on directly. The 100 ml size is particularly practical for larger massage oils and fragrance concentrates.
Areas of use

Cleaning and reuse
Clean the bottles by soaking in warm water with a neutral detergent. For stubborn scent residues, rinse with 70% isopropyl alcohol and dry thoroughly. Avoid the dishwasher, as the intense heat and alkaline detergents can damage any labelling or printed surface. Properly cleaned glass bottles can be refilled many times, and at the end of their life they can be placed in the glass recycling stream.
