All PFAS reference standards manufactured by Restek contain more than 1.2 mL of solution in each ampul. We do this to ensure you receive at least 1.2 mL of usable material after minor pipetting or transfer losses. Your CofA shows this as > 1.2 mL.
Note: Restek has not changed how much standard is provided in each PFAS ampul. All PFAS standards manufactured by Restek, even if labeled as 1 mL, contain >1.2 mL.
