Frequently Asked Questions
1. What is the advantage of using strips over indicator paper rolls?
Indicator strips, like the LLG Universal series, typically feature non-bleeding indicator zones fixed to a plastic handle, which prevents dye from contaminating your sample and protects your fingers from chemical contact.
2. How accurate is pH indicator paper compared to a meter?
Indicator paper is ideal for rapid screening and typically provides accuracy within 0.5 to 1.0 pH units; for results requiring 0.01 precision, a digital pH meter should be used.
3. What is "DuoTest" paper?
Macherey-Nagel DuoTest paper features two different indicator zones on a single strip, which provides a unique color combination for each pH value, making it significantly easier to read than single-zone papers.
4. Can indicator paper be used in colored or turbid samples?
Highly colored or turbid samples can mask the color change on the paper; in these instances, a pH electrode is the preferred method for accurate measurement.
