Rollflaschen<\/a>?<\/p>\n\n\n\nA: This is usually due to “Thermal Expansion” or “Capillary Action.” Essential oils have a high coefficient of expansion. If a roller essential oil bottles is filled to 100% capacity in a cold environment and then moved to a warm one, the oil expands, forcing its way through the thread. Engineers solve this by specifying a “Maximum Fill Line” (usually 90% of brimful capacity) to allow for a thermal “Air Buffer.”<\/p>\n\n\n\n
Q2: What is the benefit of “Vitreous Enamel” graduations on essential oil dropper bottles?<\/p>\n\n\n\n
A: Unlike standard ink, vitreous enamel is actually a form of liquid glass. Once fired, it becomes part of the bottle’s structure. In an essential oils bottle environment, where the oils can act as a solvent to remove standard printing, vitreous enamel is the only way to ensure the dosage markings remain visible for the life of the product.<\/p>\n\n\n\n
F3: Kann ich 18\/400- oder 18\/410-Verschl\u00fcsse austauschbar auf Flaschen mit \u00e4therischem \u00d6l verwenden?<\/p>\n\n\n\n
A: No. While the “18” refers to the diameter in millimeters, the “400” or “410” refers to the thread finish (the number of turns). An 18\/410 finish has more thread turns than an 18\/400. Using the wrong cap on an essential oils bottle will lead to “Thread Stripping” or a failure of the hermetic seal, causing the oil to oxidize.<\/p>\n\n\n\n
Q4: How does the “Shore A Hardness” of a dropper bulb affect user experience?<\/p>\n\n\n\n
A: Shore A Hardness measures the flexibility of the bulb. A bulb that is too hard (High Shore A) makes it difficult for the user to control the number of drops dispensed. A bulb that is too soft may not have enough “Suction Power” to draw up thicker oils. For most essential oil dropper bottles, a Shore A of 45-55 is the “Sweet Spot” for control and durability.<\/p>","protected":false},"excerpt":{"rendered":"
