Xpress Flex® Proper Techniques for Testing

Pour your sample water into the center chamber on the test vial (~80 mL).

Carefully measure prep reagents for Iron Prep and Phosphate Prep, and add to respective chambers.
•  1 level scoop of iron reagent to chamber 1. Note: Powder may not dissolve fully. This will not affect test results.

•  0.5 mL of phosphate reagent to chamber 4.

Use gloves and protective eyewear when handling Iron and Phosphate prep reagents. Immediately clean up any spilled reagents.

Carefully use the syringe to measure sample water from center chamber of test vial and add to chambers 1 and 4.

•  Add 5 mL of sample water to both chambers.

Cap center chamber of test vial and swirl to mix.

Dip timing is important. Pay attention to the sounds and animation as instructed. Remove promptly. Avoid flinging water.

When dipping strips, be sure numbers on clip and testing vial line up.

Avoid handling test strips near pads when loading into Xpress Flex.

Follow all program prompts.

Never dip into the same sample twice.

Keep lids of the test strip bottles closed when not in use.

If Xpress Flex shuttle starts accumulating water, use a dry cloth to remove.
