• Gradation (pH): less than 7.2 - 7.2 - 7.5 - 7.8 - 8.1 - 8.4 - 8.7 - 9.0 - 9.3 - 9.7 - greater than 9.7

• Singly sealed to ensure long-term stability and protection against many external influences

• Have to be placed in the plastic reel with color scale to be used

• Gradation (pH): less than 7.2 - 7.2 - 7.5 - 7.8 - 8.1 - 8.4 - 8.7 - 9

• Tritest indicator paper has 3 different indicator zones on a single paper

• The 3 zones guarantee optimal color differences and safe determination of in-between values

• Gradation (pH): 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 - 11 <

• 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 <

• Quick and easy determination for neutralisation analyses

• White paper, which changes colour to red when the pH exceeds 8.3 towards alkaline conditions (red at pH > 10)

• 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): 1 -

• Gradation: 0 - 5 - 20 - 50 - 100 - 250 mg/L Mo6+

• Color change: white to green

• The fastest qualitative filter paper with highest flow rate

• This very soft filter paper is used for example in routine clean up of large volumes of sample with coarse particles

• Surface: Smooth

• Basis weight: 85 g/m2 <

• MN 615
• Equivalent to Whatman Grade No. 1
• Medium fast filtration for general laboratory use

• Equivalent to Whatman No. 40

• Ashless filter paper, which is slightly more retentive than MN 640 m with corresponding increase in filtration time

• Surface: Smooth

• Basis weight: 85 g/m2

• Thickness: 0.2 mm

• Quick and easy determination of water hardness

• Gradation (Total Hardness): < 54 > 90 > 180 > 270 > 360 > 450 ppm CaCO3

• Color change (Total hardness): Green to red

• Allows the specific detection of lactoperoxidase in milk

• In the dairy industry, the test is used for the quick and easy quality control of highly heated milk

• In contrast to the alternative guaiacol method, Peroxtesmo MI is odor

• Wet-strengthened, ashless filter paper, which is slightly more retentive than MN 1640 m with corresponding increase in filtration time

• The smooth surface allows fiber-free filtration, even for highly acidic and basic media

• Surf

• Gradation (pH): 8.0 - 8.2 - 8.4 - 8.7 - 9.0 - 9.2 - 9.6 - 10.0
