Product Overview and Fluorination Technology

The 250ml white fluorinated bottle (SKU: P1518616) is manufactured using an online fluorination process, in which the interior surface of the bottle is exposed to fluorine gas during production. This treatment substitutes hydrogen atoms on the polymer surface with fluorine atoms, creating a barrier layer that markedly reduces the permeation of organic solvents, aromatic compounds, and other aggressive chemicals through the container wall.

Online fluorination is performed during the blow-moulding stage, ensuring uniform surface treatment across the entire inner wall. The resulting bottle is well suited for storing reagents that would otherwise interact with, or permeate through, standard untreated polyethylene bottles. The white body allows for easy label application and basic content visibility checks.

This SKU does not carry a UN hazardous goods code, indicating it is supplied as a standard laboratory packaging component rather than as a UN-certified transport container for dangerous goods. Researchers should verify their own regulatory requirements for transport and storage.

Compatible Closure and Liner Specifications

Proper sealing is critical for maintaining reagent integrity and preventing leaks. This bottle is designed to be used with two specific accessories:

• [P1134] Red anti-theft cap (42 mm outer diameter): The tamper-evident red cap provides a secure, visually distinctive closure. The 42 mm outer diameter is matched to the bottle neck finish, ensuring a reliable fit that minimises the risk of accidental opening or tampering during storage and transit.
• [P6896] Double-sided coated PE foam gasket (39.2 × 2.0 mm): This gasket is inserted inside the cap to create a hermetic seal between the cap and the bottle lip. The double-sided coating enhances adhesion and chemical resistance, while the precise dimensions (39.2 mm diameter, 2.0 mm thickness) are engineered to match the 42 mm cap assembly, providing consistent compressive sealing force.

Using non-specified caps or gaskets may result in inadequate sealing, potential leakage, or chemical incompatibility. Aladdin Scientific recommends always pairing P1518616 with accessories P1134 and P6896 for optimal performance.

Chemical Compatibility and Recommended Applications

Fluorinated polyethylene bottles offer substantially improved chemical resistance compared with standard HDPE bottles, particularly for:

• Aromatic and aliphatic hydrocarbon solvents (e.g., toluene, xylene, hexane)
• Halogenated solvents (e.g., dichloromethane, chloroform)
• Agricultural chemicals and pesticide formulations
• Essential oils and fragrance compounds
• Certain acids and aggressive reagents at moderate concentrations

The fluorination barrier reduces both solvent permeation through the bottle wall and the absorption of active ingredients into the polymer, helping to preserve reagent concentration and purity over time. This makes the bottle particularly valuable in analytical chemistry, formulation science, and long-term sample archiving.

Note: Chemical compatibility should always be verified independently for specific reagents and concentrations. Fluorination does not render the bottle compatible with all chemicals, and compatibility data for the specific reagent should be consulted before use.

Ordering, Regulatory, and Safety Considerations

UN Code Status: P1518616 is supplied without a UN hazardous goods code. This means the bottle itself is not certified as a UN-approved packaging for the transport of dangerous goods under international transport regulations (e.g., ADR, IATA, IMDG). Customers requiring UN-certified packaging for the transport of classified hazardous substances must source appropriately certified containers and verify compliance with applicable regulations.

Ordering Accessories: To complete a functional packaging assembly, order the matching cap (P1134) and gasket (P6896) separately. Ensure quantities of caps and gaskets match the number of bottles ordered.

Storage of the Empty Bottle: Store empty fluorinated bottles in a clean, dry environment away from direct sunlight and sources of heat to preserve the fluorinated barrier layer and prevent deformation.

Disposal: Dispose of used bottles in accordance with local regulations for plastic waste, taking into account any residual chemical contents.
