Very easily, as follows:
- Open the peel pouch at the opposite end to the loop.
- Be careful to only touch the handle and not the loop.
- Dip the loop into the water or oil sample you wish to test.
- Ensure the liquid forms a layer across the surface of the loop.
- Transfer the loop to the test kit you are using.
- Agitate the loop in the test kit you are using to transfer the sample to the test kit.
