Macherey- Nagel 92110 0-14 pH Indicator Strips 100box

Macherey- Nagel, 92110, 0-14 pH Indicator Strips 100/box

Macherey- Nagel, 92110, 0-14 pH Indicator Strips 100/box - Coming with a complete color chart the test strips are already calibrated. This protects the sample against contamination and enables measurements in weakly buffered or strongly alkaline solutions. For careful testing of dangerous, poisonous or aggressive liquids the strips have the optimal design. The color chart exactly matches both color and position of the pads on the strips. They are always ready for immediate use. Patented technology for optimal sample protection in the production the indicator reacts with the paper of the test pad to form a chemical bond. The dye is fixed to the test strip and can not bleed into the sample. Brilliant colours for exact results ph-fix test strips feature up to four different indicator pads to cover the complete ph range. Ph-fix test strips are used for rapid ph testing directly at the point of interest. This enables highly precise ph determination and makes the test strips rapid and reliable. As single use devices they are completely maintenance free. The longest available handle effectively protects the user from contact with the sample. Always ready for use. This increases the safety of operation and adds handling ease.
