[0026] For example Figure 1 As shown, the filter module 100 is placed in the water area 600 , and the water sample can be pumped from the filter module 100 to the debubble device 200 by a pump. The water sample can be precisely filtered through the filter module 100 to reduce impurities in the water sample entering the debubble device 200 .
