How do I store my lipid in an organic solution?

Phospholipids supplied as an organic solution should be stored in a glass container layered with argon or nitrogen at -20°C ± 4°C. Storage of organic solutions below -30°C is not recommended unless the solution is packaged in a sealed glass ampoule. The closure for the vial should be lined with Teflon. Organic solutions should never be stored in polymer or plastic containers, or transferred with pipette tips (polystyrene, polyethylene, polypropylene, etc.) as this will leach impurities out of the plastics.
