Manufactured from amber PET (polyethylene terephthalate) for excellent clarity, chemical compatibility and recyclability. Each bottle includes a polypropylene (PP) screw cap with an inner polyethylene (PE) liner to help create a tight, leak-resistant seal. Amber pigmentation provides increased protection against UV and visible light for light-sensitive formulations.

Rinse bottles with warm soapy water or an appropriate solvent and allow to fully dry before first use. Fill bottles leaving a small headspace to allow for expansion. Secure the screw cap firmly to ensure a tight seal. Label bottles clearly with product name, batch and date. For best results, use a filling rack or funnel for consistent fills in bulk applications.

Designed for small businesses, makers and laboratories: essential oil producers, herbalists, cosmetic formulators, supplement companies, apothecaries, e‑commerce sellers and research labs who need reliable, affordable 50ml amber bottles in bulk.

Not suitable for autoclaving or microwave sterilization. Avoid prolonged exposure to high heat or open flame. Test compatibility before storing highly concentrated solvents (e.g., acetone, strong acids) as some aggressive chemicals can degrade plastic. Keep out of reach of children. Store capped bottles in a cool, dark place to preserve formulation integrity.
