MACHEREY-NAGEL Test papers for qualitative determinations/ AQUATEC Test strips
Qualitative determination of ions and chemical compounds
With the aid of test papers for qualitative determinations, the presence of Ion and chemical compounds can be asserted with low effort.
A color change is effected, if the concentration of the researched substance is situated above the specific detection limit.

MACHEREY-NAGEL AQUATEC Test strips
Quick and easy determination of water in oil tanks
This test allows the quick and easy measurement of the water amount at the bottom of petrol and fuel oil tanks.
In petrol and fuel oil tanks water accumulates over time building a layer at the bottom. To measure this layer the PE strip is fixed onto a flat steel sheet so that the lower ends coincide. It is then lowered into the tank with a tin cord until it reaches the bottom. Any water present beneath the fuel will dissolve the blue layer (testing time about 15 - 20 seconds). The thickness of the water layer corresponds to the color less part of the strip.
