The pathoscreen medium comes in pillows (like sachets) with enough powder to test 100ml of water. The sample water is put in sterilized bottles, and the contents of PathoScreen Medium powder pillow is added and left for 24 hours. The change in colour indicates the safety of the water. For more details read the attached document.

In the time that the powder is working, the sample should be stored at a temperature between 25 and 35 degrees Celsius.
