The Macherey-Nagel Visocolor ECO pH 4,0 - 9,0 is a special mixture of indicator dyes. It takes on a characteristic colour at any pH value. Due to the favourable ratio of sample volume and indicator quantity, the indicator error (acid-base error) is low. This makes reliable pH determinations possible even in weakly buffered solutions. High contents of neutral salts and colloids as well as organic solvent contents above 10 % can falsify the measurement result.
- Range: pH 4,0 – 9,0
- Sufficient for 450 determinations
- Sea water suitability: Yes
- Not evaluable with compact photometer PF-12
safety information in accordance with GHS
Signal word: Warning
- H225 Highly flammable liquid and vapour.
