• Tritest L indicator paper has 3 different indicator zones separated by two hydrophobic barriers

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

• Gradation (pH): 1 - 2 - 3 - 4 - 5 - 6 -

• 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 detection of aluminum and zirconium

• In the presence of aluminum (Al3+), it shows bright red spots on a yellow background

• Color reaction: yellow to bright-red

• Limit of sensitivity: 10 mg/l Al

• 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): 1.0

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

• Color change: white to red-violet

• 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

• Allows the quick and easy determination of the water quality in swimming pools

• Measures free chlorine, alkalinity and pH

• Gradation (Alkalinity): 0 - 80 - 120 - 180 - 240 mg/L CaCO3

• Gradation (Free chlorine): 0 - 0.5

• Allows the quick and easy detection of lead on surfaces including metal surfaces, dishes, ceramics and toys

• In criminal investigations, it is used to search for traces of bullets

• The surface in question is moistened with distil

• Wet-strengthened, slow, ashless filter paper with very fine particle retention

• Standard paper for critical gravimetric analysis of fine precipitates like barium sulfate or metastannic acid

• The smooth surface allows fiber-free f

• Gradation (pH): 9.0 - 9.5 - 10.0 - 10.5 - 11.0 - 11.5 - 12.0 - 12.5 - 13.0
