Camlab 1138846 PEHANON pH 4.0-9.0 Strip, 11 mm Length x 100 mm Width (Pack of 200)

• An invisible hydrophobic barrier just above the top colour field prevents liquid reaching the fingers

• Supplied in plastic boxes containing 200 strips 100x11mm
• Graduation: 0.5

The PEHANON range of pH indicator strips combine the pH indicator and reference colours (with corresponding pH values) onto each strip. This eliminates the need for a separate colour chart, so you will never have to worry about losing it again. The strip should be immersed so that all colour zones are wetted, enabling coloured solutions to be accurately tested if required.
