Blue Glass Bottle, Matte Black Dropper With Shiny Strip, 15 ml

This blue glass bottle with a capacity of 15 ml and a black dropper is used for packaging small quantities of liquid preparations that are dispensed drop by drop. Blue glass reduces the amount of light reaching the contents, so light-sensitive contents stay in their original condition longer than in a clear container. The dropper lets you take exactly as much as you need, without pouring and without your fingers touching the contents.

The set is supplied as one piece. The pharmaceutical bottle with an 18 mm neck and the dropper fit together, so you do not need to choose them separately. The black matte head with a glossy stripe distinguishes the packaging from ordinary all-black or white droppers, which is useful for your own brand or a gift set.

Suitable uses

• Facial and oil serums – a small amount is applied drop by drop directly onto the palm or skin.
• Essential oil blends – concentrated fragrance blends are diluted drop by drop, and blue glass slows their ageing in light.
• Alcohol-based preparations – glass does not react with alcohol, and the dropper makes precise dispensing into the finished product easier.
• Samples and trial batches – when testing a new recipe, it is enough to fill 15 ml rather than a whole retail bottle.

Filling and dispensing

The bottle has a nominal volume of 15 ml, which is the amount it is intended for in normal filling. The total brim-full volume is larger and can be found in the parameters. The difference between the two values provides a reserve for the dropper tube immersed in the contents and for the expansion of the contents when the temperature changes. For this reason, fill to the nominal volume, not up to the neck.

Dispensing is done by squeezing the bulb, immersing the tube in the contents and releasing it slowly. Thin oils and serums are drawn in smoothly. Thicker oils are drawn in more slowly and the drop is larger, which should be taken into account in the dispensing instructions.

Good to know

• Preparation before first filling – wash and disinfect the bottle and the dropper and let them dry completely. For the dropper, draw the solution through the tube as well.
• Glass and heat – pour in the contents only after they have cooled, as a sudden temperature change can damage the glass.
• Dropper materials – the dropper combines polypropylene, glass and silicone. With undiluted essential oils, solvents or a high proportion of alcohol, check the tightness and the behaviour of the silicone and plastic parts with your specific formulation before sale.
• Suitability for cosmetics – the dropper has a declaration of suitability for contact with cosmetic products, and the document is provided with the product. The bottle itself does not have such a declaration. The set is not approved for contact with food.
• Reuse – after thorough washing and disinfection, the set can be used again. Before refilling, check that the silicone part keeps its shape and that the dropper still draws in liquid.
• Other closures – other closures with the same neck type stated in the parameters also fit the bottle. You can find ready-made combinations in the Handymade range; if you make your own combination, check the tightness.
