Sanitize a clean and flat working space with disinfectant cleaning solution, paper towels or wipes.
Put gloves on if possible. Avoid touching the inside of the bags with your fingers, as this may cause the test to work improperly.
Tear off the perforated seam on the top of the Whirl-Pak (the small rectangular bag without separate compartment) and open it by pulling apart the two tabs in the middle.
Fill the Whirl-Pak with water up to the 100 mL black line (the bottom line).
Using a pair of scissors, open the Aquagenx Test Medium packet, being sure not to spill any of the powder
Carefully pour the powder into the Whirl-Pak with your water sample.
Roll down the bendable metal seal 3-4 times, ensuring it stays above the water level.
Fold over the metal tabs to close the Whirl-Pak completely.
Gently swirl the Whirl-Pak until the powder is completely dissolved (should take roughly 30 seconds).
Once dissolved, you may set the Whirl-Pak aside and prepare the Compartment Bag.
Tear off the perforated seam on the top of the compartment bag.
Open the compartment bag by pulling apart the two tabs in the middle. Do not touch the inside of the bag with bare hands or fingers.
Rub the sides of the compartment bag together between your fingers so that the water sample can easily run into the compartments.
Slowly pour the water sample from the Whirl-Pak into the compartment bag.
Ensure that each compartment is filled to the black fill line. Tilt the bag and squeeze the compartments to assist in distributing the water.
It is okay if it’s not perfect, but try to align water to the black lines to the best of your ability.
Close the compartment bag by first rolling down the yellow seal 3-4 times, then folding in the sides of the yellow seal that stick out. Make sure not to roll the seal down too much - just above the edge of the compartments is sufficient.
Place the rod-shaped part of the clip against the bag so that it is above the black fill line, but below the edge of the compartments.
Place the U-shaped part of the clip on the opposite side of the compartment bag.
Snap the two pieces together, ensuring that the compartments are now sealed.
