• GL-18 screw neck for standard closures
• No closures included — choose suitable caps
• 33.0 mm outer diameter for compact storage
• Lightweight glass: 45 g per bottle

Proven protection for light-sensitive contents

The blue glass reduces light transmission and supports stability of sensitive formulations. The 30 ml format keeps batches manageable while limiting exposure during handling. Compatibility with standard GL-18 closures maintains dosing accuracy and storage integrity.

Accurate dimensions for process planning

With a 33.0 mm diameter and 78.8 mm height the bottle fits common filling heads and trays. The precise GL-18 neck dimension ensures consistent sealing when paired with matching closures. Weight is 45 g, allowing straightforward calculation of transport loads.

Flexible closure options for varied applications

The bottle is supplied without closures so compatible caps or droppers can be selected per application. Options include droppers, pipettes, or spray pumps from accessories. This flexibility supports both laboratory sampling and small-scale production runs.

Designed for efficient handling and storage

The compact shape enables dense shelf packing and optimizes bench space. Bottles stack securely in trays and fit automated gripping systems. For commercial fillers, VPE scaling is aligned with palletized shipments to facilitate larger orders and handling efficiency.

Material reliability and recyclability

Made from glass and coded under recycling classification 73: GL, the bottle provides chemical resistance and inert contact surface for a wide range of formulations. The robust glass construction supports repeated handling in production environments.

Documentation and traceability

Technical data and the product sheet are available in the accompanying documentation to support QC and process integration. Use the datasheet to confirm neck dimensions, material specifications, and handling recommendations.

Select the Blue Glass Dropper Bottle GL-18 when light protection, dimensional accuracy, and flexible closure choice are priorities for your production or lab workflows.

Core features

Blue glass for light-sensitive formulations

Blue-tinted glass lowers light exposure and helps preserve photolabile ingredients while maintaining chemical inertness and compatibility with most formulations.

Standard GL-18 neck interface

The GL-18 screw neck provides an industry-standard interface for a wide range of caps, droppers, and pumps, ensuring interchangeability across accessory types.

Compact, predictable dimensions

At 33.0 mm diameter and 78.8 mm height the bottle integrates with common filling and capping equipment and supports compact logistics and storage planning.

Supplied without closures for application-specific choice

No caps are included, enabling selection of droppers, pipettes, or spray pumps tailored to end-use requirements and dosing precision.
