Frequently Asked Questions Narrow Mouth Bottle

This certification means the polypropylene resin used to manufacture these bottles meets the strict requirements of the US Food and Drug Administration (FDA) as outlined in Title 21 of the Code of Federal Regulations. It confirms that the material is safe for direct contact with food products and pharmaceutical ingredients, as it does not release harmful substances into the contents under normal conditions of use.

Yes, when the polypropylene screw cap is properly sealed, these bottles are completely leakproof. The closure system is designed to provide a tight, secure seal, making them suitable for the safe storage and transport of liquids without the risk of spills or leaks.

To autoclave these bottles safely, always loosen the cap by one full turn to allow steam to enter and pressure to equalize, preventing deformation or implosion. Autoclave at standard cycles of 121°C (250°F) at 15 psi. Repeated autoclaving will not degrade the polypropylene, ensuring a long, reusable lifespan.

Yes, polypropylene maintains its mechanical strength and flexibility at low temperatures, making these bottles suitable for freezer storage down to -80°C. When freezing liquids, especially aqueous solutions, remember to leave at least 10-15% headspace to accommodate volume expansion and prevent the bottle from cracking.

While dimensions can have minor tolerances, the approximate sizes are:
2000 ml: 185 mm (H) x 120 mm (Dia)
4000 ml: 245 mm (H) x 160 mm (Dia)
8000 ml: 325 mm (H) x 190 mm (Dia). For precise specifications, please consult our technical datasheet or contact our support team.

These polypropylene bottles offer excellent resistance to a wide range of substances, including most dilute acids, bases, alcohols, and aqueous solutions. However, they may not be suitable for strong oxidizing agents, concentrated sulfuric acid, or some non-polar solvents like toluene and xylene. Always consult a chemical resistance chart for your specific reagent.

For initial cleaning, wash the bottles with a mild, non-abrasive laboratory detergent and warm water. Use a soft brush for the interior if necessary. Rinse thoroughly multiple times with tap water, followed by a final rinse with distilled or deionized water. Allow them to air dry completely before first use or proceed with sterilization if required.
