Instructions for water sampling
The minimum volume of water for analysis is 2 liters
1
Leave the water to drain for 5-10 minutes
2
Rinse the bottle and lid with water taken for analysis without using detergents
3
Pour water carefully over the wall of the bottle so that there are no air bubbles in it
4
Fill the bottle with water to the top to keep a minimum of air in the bottle. Close the lid tightly
