Protected Storage for Light-Sensitive Formulations

Designed for Photostable Storage, the Blue Glass Dropper Bottle, 50 ml (GL-18) delivers reliable Light Protection for formulations prone to photodegradation. The colored Glass reduces transmission in the UV/visible range, which preserves active ingredients during short- and medium-term storage. This Bottle geometry also supports controlled headspace, minimizing oxidation risk for sensitive extracts and tinctures.

Precise Dispensing and Closure Flexibility

With a GL-18 Screw Neck and compatibility with Droppers, Pumps and Glass Pipettes, this Bottle enables controlled dosing workflows in production and R&D settings. The 50 ml Volume and narrow Neck facilitate reproducible fill volumes and reduce product loss during transfer. Operational teams benefit from reduced dosing variability and streamlined assembly when using standardized Closures.

Robust Handling and Logistic Advantages for Professionals

The lightweight construction (approx. 55 g) simplifies manual filling and reduces transport mass while maintaining dimensional stability for automated lines. Packaging unit tiers (VPE) are tailored to commercial fillers, and full Pallet Units are available for bulk Buyers, allowing efficient stock planning and optimized inbound logistics for contract filling operations.

Choose the Blue Glass Dropper Bottle 50 ml (GL-18) to standardize dispensing processes and secure light-sensitive contents in both laboratory and small-series production environments.

Core Features

Blue Glass for Photoprotection and Stability

The Blue Glass minimizes harmful light exposure and thereby extends the shelf integrity of light-sensitive formulations. This Bottle is specifically shaped to reduce surface exposure and ensure consistent protection across filled units, supporting quality retention for actives and botanical extracts.

GL-18 Screw Neck for Universal Closure Options

A standardized GL-18 Neck enables rapid adaptation to a wide range of Closures, from dropper inserts to fine bore Pipettes and spray pumps. This flexibility reduces variant complexity in procurement and allows compatibility with existing dosing accessories in laboratory and production settings.

Compact 50 ml Volume Suited to Sampling and Small Batches

The 50 ml Capacity is ideal for pilot Batches, sample distribution and cosmetic trial sizes, offering a balance between manageable fill volumes and prolonged usability. The Bottle format supports accurate portioning without excessive headspace, facilitating reproducible sampling and QC procedures.
