Test sticks for fast, semi-quantitative determinations of different parameters in solutions. Indication test papers meet the requirements of a modern testing method:

Fast: dip in and read off
Easy-to-use: only a test stick is required for a screening test – no apparatus equipment is needed
Long life: can be used for 2 years when stored below 30°C
Indicator test sticks are packed at container.
