pH-indicator strips universal, pH 1-14 non bleeding, 100 tests

Strips of plastic, gradation 1 ph.

• For fast reading
• Ideal for measuring the pH of weakly buffered or highly alkaline solutions
• The indicators do not bleed because they are bound to the cellulose fibres, no pollution, so the solution can be reused for other determinations
• Reliable measurement of weakly buffered solutions because the strip can remain immersed in the solution until the definitive colour is obtained
• Different coloured indicator zones which are sufficiently separated to ensure a clear reading
• Rigid plastic strip for improved handling
• Transparent plastic box containing: 100 strips 6 x 80 mm + colour scale
• Dim.: 6 x 80 mm
