Important notes for using the Algae Management Colorimetric
Comparator Test Kits
Before testing clean the glass vials and the large syringe by rinsing it with the water to be
•
tested.
After testing rinse all syringes and vials with RO or distilled water before storing. If vials are
•
left unwashed a residue can form that will affect the results of future tests. Use a slightly
acidic solution such as vinegar to remove the residue.
In order to ensure an accurate drop size always hold reagent bottle vertically above the
•
test vial, and gently squeeze out each drop
• Close all reagents tightly immediately after use.
The test reagents are stable up to the date stated on each bottel when stored closed
•
between 15 – 25 °C.
Store the reagents and color card in the plastic box to prevent damage from prolonged
•
exposure to light.
