The ph scale is traceable to a set of standard solutions whose ph is established by international agreement. Primary ph standard values are determined using a concentration cell with transference, by measuring the potential difference between a hydrogen electrode and a standard electrode such as the silver chloride electrode. If youre interested in testing the alkalinity or acidity of a liquid, you can use ph strips to help you determine the ph level. If youve never used a ph strip, though, it might look like just a plain strip of. In order to deal with these large numbers more easily, scientists use a logarithmic scale, the ph scale. Each one-unit change in the ph scale corresponds to a ten-fold change in hydrogen ion concentration. The ph scale is theoretically open-ended but most ph values are in the range from 0 to 14. The ph scale runs from 0 to 14, with each number assigned a different color. At the bottom of the scale sits red, which represents the most acidic, and a dark blue at its opposite end represents 14 and alkalinity. Lower numbers are increasingly acidic, while higher numbers are increasingly alkaline (or basic). Ph indicator strip may be used during the synthesis of modified nucleotides, for site-directed dna photoaffinity labelling of rna polymerase iii transcription complexes. Features and benefits each strip has an identification scale and printed ph scale. The strips can be utilized in colored solutions and suspensions with very high precision. The brilliant color scale is optimally matched and aligned to the test pads on the strips, resulting in quick, easy and safe ph determination. In contrast to common indicator papers, the indicator dyes in ph-fix test strips are chemically bound to the test pads.

Using these test strips is fairly easy, the ph value is measured semiquantitatively by visual comparison of the four reaction zones on the test strip with the fields of the color scale, perfectly matching the reaction color. The clever safetyedge boxes allow for safe storage and convenient withdrawal of the test strips.
