Archival, Field and Laboratory Products for Canadians
With a simple swipe of Lineco's pH testing pen, you can determine whether the paper you are using is acidic. This easy, convenient, method allows you to distinguish between safe (neutral or alkaline) paper and acidic materials. Easy to use, simply draw a small line on the material you wish to test. The chlorophenol red indicator solution in the pen will turn purple on any paper with a pH of 6.8 and above. A clear or yellow color indicates the material is probably unsuitable for conservation purposes. Please note: unreliable results may occur on colored or coated papers.
