Macherey-Nagel

• Filter paper with medium retention and flow rate

• This filter paper covers a wide range of filtration applications

• Surface: Smooth

• Basis weight: 85 g/m2

• Thickness: 0.2 mm

• Filtration speed: 27 s <

• 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 ont

• Fastest, wet-strengthened, quantitative filter paper with highest flow rate

• Used for example in analytical procedures of samples with coarse or gelatinous particles

• The smooth surface allows fiber-free filtration, even for high

• Unify pH indicator and reference color chart on one strip

• Any sample color has the same effect on both, the reference colors and the reactive pad, allowing unadulterated pH reading even in colored solutions

• Gradation (pH): 3.8

• For the determination of Nitrite and pH

• Gradation: 0 - 1 - 5 - 10 - 20 - 40 - 80 mg/L NO2- (Nitrite)

• Gradation: 6.0 - 6.4 - 6.7 - 7 - 7.3 - 7.6 - 7.9 - 8.2 - 8.4 - 8.6 - 8.8 - 9.0 - 9.3 - 9.6 (pH)

• Color change: white
