REAGENT SHELF LIFE. All reagents have a shelf life, whether they are liquids, powders, crystals, tablets, or teststrip pads. If kept dry, powders and crystals are very stable; acids are also long lived. Date of manufacture is not the controlling factor when it comes to shelf life—storage
The Folin–Ciocâlteu reagent (FCR) or Folin''s phenol reagent or Folin–Denis reagent, also called the gallic acid equivalence method (GAE), is a mixture of phosphomolybdate and phosphotungstate used for the colorimetric in vitro assay of phenolic and polyphenolic antioxidants. It is named after Otto Folin, Vintilă Ciocâlteu, and Willey Glover Denis.
Once the Reagent is Opened: When stored capped at 28°C, the reagents are stable until the expiration date stated on the bottle and kit box label. Combined reagent is stable for at least 5 days when stored at 2 8°C. Indications of Reagent Deterioration: • Turbidity; • Reagentabsorbance>(1cmlightpath);and/or
For use on containers that store Copper Reagent to ensure the workplace is aware of the immediate chemical hazards that are present. Compliant with the OSHA Hazard Communication Standard and aligned with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) Made in the United States of America

To differentiate free copper from that complexed to EDTA or other complexing agents, use the powder pillow procedure with the information that follows: • Use a 25mL sample and 25mL sample cells. • Add a Free Copper Reagent Powder Pillow for 25mL samples in step 3. Do not add the CuVer 1 reagent.
Copper (CU) is an essential trace mineral, naturally available in some foods and as dietary supplements. CU is a cofactor for several enzymes, known as cuproenzymes, which are involved in connective tissue synthesis, energy production, iron metabolism, neuropeptide activation and neurotransmitter synthesis.
