Buying advice

Choose a base that matches your application’s strength and safety needs: solid NaOH or KOH for high-pH work, ammonia for liquid buffering, Ca(OH)₂ or Mg(OH)₂ for food-grade or mild uses, and triethylamine when an organic, non-aqueous base is required. Consider purity, storage conditions, and handling precautions when selecting.
