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

• Gradation (pH): 3.1 - 3.5 - 3.9 - 4.

• For use in Food processing industry

• For the rapid and reliable determination of chloride in solutions

• The easy dip-and-read-procedure provides a reliable result within 1 minute

• Chloride ions occur in all natural wate

• Wet-strengthened, ashless, very slow filter paper for the filtration of finest particles in quantitative range

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

• Surface: Smooth

• B

• 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

• Best-known indicator paper

• Changes color from red to blue when conditions change from acidic to alkaline

• 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
