Macherey-Nagel

• Equivalent to Advantec Filter Paper No. 5C

• Equivalent to Whatman Filter Paper No. 42

• Ashless, slow filter paper with very fine particle retention

• Standard paper for critical gravimetric analysis of fine precipitates

• With chemically bound indicators which prevents bleeding and therefore contamination of the sample

• Gradation (pH): 4.0 - 4.4 - 4.7 - 5.0 - 5.3 - 5.5 - 5.8 - 6.1 - 6.5 - 7.0

• Length: 85 mm

• Width: 6 mm

• Allows the quick and easy detection of low range total Chlorine (total chloramines). The easy dip-and-read procedure provides reliable results within 20 sec

• Chlorine is mainly known for its use as a disinfectant, but used in many other a

• 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 <

• Equivalent to Whatman No. 41

• Fast, ashless filter paper

• Recommended for analytical procedures involving coarse particles or gelatinous precipitates

• Surface: Smooth

• Basis weight: 85 g/m2

• Thicknes

• Yellow paper which changes to blue when the pH exceeds 6 towards alkaline conditions (greyish blue at pH 7, blue at pH >?8), e.g. for neutralization analyses

• Color change (pH): yellow-blue to violet

• Length: 70mm

• Widt

• Allows the quick and easy detection of hydrogen sulphide, which occurs in the processing of raw oil. It is toxic even in low concentrations. Therefore, critical points are carefully checked. Sulfide containing solutions also give a positive reaction

• Wet-strengthened, general purpose, ashless filter paper with medium speed and medium retention

• Typical applications include gravimetric analysis for components, quantitative determinations of sediments and high purity clean up procedures

• 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): 0.5 - 1.0 - 1.5 - 2.0 - 2.5 - 3.0 - 3.5 - 4.0 - 4.5 -

• Gradation: 0 - 5 - 20 - 50 - 100 - 250 - 500 - 1000 mg/L Fe2+ 3+

• Color change: white to dark red

• Equivalent to Whatman No. 4

• Fast filter paper with excellent retention of coarse particles and gelatinous precipitates

• This soft filter paper is used for example in routine clean up of biological or organic solutions

•

• Allows the rapid and reliable detection of oil contaminations of water and soil

• The sensitivity largely depends on the nature of the respective hydrocarbon

• For detection of oil in soil, press the paper firmly against the soil t

• Ashless, very slow filter paper for the filtration of finest particles in quantitative range

• Surface: Smooth

• Basis weight: 100 g/m2

• Thickness: 0.2 mm

• Filtration speed: 195 s

• Material: Cellulose

• With chemically bound indicators which prevents bleeding and therefore contamination of the sample
