Frequently Asked Questions Reagent Bottles (Narrow Mouth)

This certification means the polypropylene material used to manufacture these bottles meets the strict requirements of the US Food and Drug Administration (FDA) under Title 21 of the Code of Federal Regulations. It ensures that the material is safe for direct contact with food, pharmaceuticals, and clinical samples, and will not leach harmful substances into your reagents.

Yes, these polypropylene bottles are designed to withstand autoclaving at 121°C (standard sterilization temperature) even when filled with liquid. However, it is important to loosen the cap slightly during autoclaving to allow pressure equalization, and to ensure the liquids being autoclaved are compatible with PP at high temperatures.

The PP cap features a built-in seal ring that creates a highly effective leakproof closure. When tightened properly, the seal ring compresses against the bottle neck, preventing liquid leakage even when the bottle is inverted or shaken. This makes these bottles ideal for storing volatile reagents and for transport between laboratories.

Narrow mouth bottles, like these, are designed for storing and dispensing liquids with controlled pouring. The smaller opening reduces evaporation, minimizes spillage, and allows for precise dispensing. Wide mouth bottles are better suited for solid materials, powders, or viscous substances that require easier access with spatulas or scoops.

Polypropylene (PP) has good chemical resistance to many organic solvents, including alcohols, acetone, and dilute solutions. However, it may not be suitable for strong non-polar solvents like toluene, xylene, or chloroform, which can cause swelling or degradation. Always check chemical compatibility charts for specific solvents before long-term storage.

This packaging strategy reflects typical laboratory usage patterns. Smaller volumes (4 ml to 60 ml) are often used for precious reagents, single-use aliquots, or multiple samples, requiring higher quantities. Larger volumes (125 ml to 1000 ml) are typically used for bulk storage of frequently used buffers and solutions, where fewer bottles are needed. This approach provides the best value and reduces waste.

Excellent contact clarity refers to the transparency of the polypropylene material when in direct contact with liquids. While PP is naturally translucent rather than completely transparent like glass, these bottles are manufactured to maximize clarity, allowing you to clearly see the liquid level, color, and any particulate matter inside without opening the bottle.
