Poşetin içindeki plastik pipet ile 3-4 damla su alinarak ok ile işaretlenmiş olan numune kuyucuğuna boşaltılır.

Thank you very much in advance

 Sounds like you are in a chemistry lesson!

Take 3 or 4 drops of the water using the plastic pipette in the bag, and empty it out into the sample well (type of test tube?) marked with the word OK.

Teşekkürler

You are welcome.
