Methanol based solutions will turn base-neutral solutions yellow and acid solutions red. Instantly know whether your solution has been pH adjusted for base-neutrals or acid extractions. The color indicator is non-extractable and will not affect results. Color coded surrogates are supplied in 25mL volume screw top vials.
 
All surrogates are supplied with Certificate of Analysis and MSDS.
 
Store surrogates in refrigerator.
