What is Reagent Bottle

Reagent bottles are integral parts of laboratories for storing chemicals, solutions, and reagents safely and preserving them properly. Crafted from either glass or high-grade plastic materials, these durable containers offer chemical resistance while being long-term storage solutions. Reagent bottles come in different sizes for individual experiments as well as bulk storage needs, with wide mouths designed for easy pouring and filling as well as secure screw caps or stoppers to help seal them shut securely. Glass and plastic bottles offer safe handling of substances by preventing leakage or contamination, and feature transparent designs to allow visual inspection.
Glass bottles offer visual verification while lightweight plastic ones offer lightweight and shatterproof qualities - some bottles even feature graduated markings for precise measurement. Reagent bottles play an essential role in maintaining the quality and integrity of laboratory substances, providing accurate scientific analysis and experimentation. From research labs to pharmaceutical manufacturers and educational settings, reagent bottles provide essential tools for safe chemical handling.

2 Commons Types of Reagent Bottle

Market offerings provide various reagent bottle types that suit laboratory requirements and needs. Understanding their differences is critical in selecting an option most suited to your applications; here, we offer an in-depth overview of amber, brown, and clear glass reagent bottles available today as well as their distinctive characteristics, advantages, best uses, and special considerations to take into account when choosing between these options.

Amber Glass Reagent Bottles

Amber glass reagent bottles (commonly referred to as brown glass bottles) are distinguished by their dark brown color. Their primary function is protecting stored substances from UV and visible light that can degrade light-sensitive substances over time, providing greater integrity and stability for stored reagents. Amber glass filters out harmful light rays effectively protecting stored substances while providing UV and visible light protection - these bottles are often used for light-sensitive chemicals, pharmaceuticals, and solutions which degrade when exposed to light exposure; furthermore, these bottles also boast excellent chemical resistance making them perfect candidates for lab applications requiring light protection as well.

Clear Glass Reagent Bottles

Clear glass reagent bottles (also referred to as transparent or colorless glass bottles) are among the most frequently utilized laboratory bottles, offering easy observation and measurement of their contents. Chemically inert and corrosion-proof, clear glass reagent bottles protect stored reagents while remaining chemically inert and secure - perfect for general chemical storage, sample collection, and solution preparation - plus their transparency can provide precise measurements or visual inspection for specific tasks such as chemical storage.

Special Considerations

When selecting a particular reagent bottle type, there are a few special considerations to keep in mind. Firstly, it is essential to consider the light sensitivity of the substances being stored. Light-sensitive reagents must be stored in amber or brown glass bottles to protect them from degradation caused by UV and visible light. Secondly, the compatibility of the reagents with the bottle material is crucial. Glass reagent bottles are generally resistant to chemical reactions and offer excellent chemical compatibility, but for highly corrosive substances, it may be necessary to opt for specialized chemically resistant plastics. Lastly, it is important to consider the volume requirements, storage conditions, and specific laboratory protocols when selecting the appropriate reagent bottle type.


The availability of different reagent bottle types allows laboratory professionals to choose the most suitable container for their specific needs. Amber, brown, and clear glass reagent bottles offer distinct advantages and are designed for different applications. Amber and brown glass bottles provide protection against light, making them ideal for storing light-sensitive substances, while clear glass bottles offer excellent visibility and chemical resistance for general laboratory use. By considering the light sensitivity of the reagents, compatibility with the bottle material, and other specific requirements, researchers and laboratory professionals can ensure the integrity, stability, and efficiency of their experiments and storage practices.
