            "a": "U-100 means 100 units per milliliter. The numbers on the syringe barrel count in units where 1 unit equals 0.01 mL or 10 µL. It is a concentration standard from insulin manufacturing, not a quality grade."
        },
        {
            "q": "How do I convert U-100 syringe units to microliters for peptide reconstitution?",
            "a": "Multiply the unit reading by 10 to get microliters. So 10 units = 100 µL, 25 units = 250 µL, 50 units = 500 µL. This works because U-100 means 100 units per 1 mL, making each unit exactly 0.01 mL."

            "q": "Can I use a U-100 insulin syringe to measure bacteriostatic water for peptide reconstitution?",
            "a": "Yes. U-100 syringes offer fine graduations suited to small-volume bench work. Convert your target µL to units by dividing by 10, draw from a sealed USP-grade bacteriostatic water vial, and inject slowly through the peptide vial septum."
