Dropper Cap

Learn More About Dropper Cap

• What are the components of a glass dropper assembly?

  A complete dropper assembly consists of three main parts: a glass pipette, a black or white PP (polypropylene) bulb, and a collar (often made of ABS plastic or metal) that secures the bulb to the pipette. Some designs may also include a PTFE (Teflon) seal for an extra-tight closure.

• Are your dropper assemblies compatible with essential oils and viscous liquids?

  Yes. Our standard droppers are suitable for a wide range of viscosities, from alcohol-based perfumes to thicker oils like essential oils or serums. For very viscous liquids, we can recommend specific pipette orifice sizes and bulb materials to ensure optimal performance.

• How do you ensure the dropper provides an airtight seal?

  The seal is achieved through the precision fit of the collar, which compresses the bulb tightly onto the top of the glass pipette. When inserted into the bottle, the dropper cap screws down, creating pressure that ensures the entire assembly is leak-proof and airtight.

• Can I order just the glass pipette or the bulb separately?

  Yes, we offer individual components. You can purchase glass pipettes, bulbs, or collars separately for assembly at your facility. However, we highly recommend purchasing fully assembled droppers for consistency, efficiency, and guaranteed seal integrity.

• What customization options are available for droppers?

  We offer customization for the pipette (clear or amber glass), bulb color (typically black or white), and collar color/finish. The dropper cap can also be customized to match your main perfume cap. Custom logos on the bulb or collar are available through printing or hot stamping.
