Lovibond® UREA Reagent 1

UREA reagent 1 for urea PU = 15 ml Reagent solutions usually do not consist of one preparation, but of several components which must be added to the sample one after the other. Since both the size and number of drops have a decisive influence on the color complex to be formed, the dosage must be extremely accurate. The shelf life of liquid reagents is limited by temporary contact with atmospheric oxygen when the bottles are opened and by unsuitable storage conditions (exposure to sunlight, higher temperatures).
