The rigid plastic sticks measure 85mm (length) x 6mm (width) and feature four separate pH test zones to cover the intended pH range. Each test zone has been infused with a non-bleeding pH indicator compound, optimized to prevent contamination of the solution and to allow the measurement of highly alkaline or weak buffer solutions. When testing the pH value, the strips cause a permanent color change, even if they are left in place, e.g. when testing solutions with low ionic strength. An immediate result is obtained by comparing the color of the four test zones with the enclosed pH color chart. The pH color chart accurately matches both the color and the position of the pads on the strips. The results are easy to interpret and can be reliably determined as the pH gradations are in 0.5 steps. The pH indicator sticks are suitable for many applications, both in the laboratory and in the field. They have the advantage over other methods of pH measurement in that they do not require additional equipment compared to liquid test kits and digital meters. This makes them more portable, more durable and easily replaceable. The pH indicator sticks are supplied in packs of 100 disposable sticks. They can be stored unopened for 2 years without sunlight.\u003c\/p\u003e\u003c\/div\u003e\u003cbr\u003e","brand":"Alpha Laboratories Ltd.","offers":[{"title":"Default Title","offer_id":57032361574732,"sku":"MD-AL-01853","price":169.27,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/1056\/9036\/files\/BC_Upload_611301b9-82fb-4328-80ac-6ceb1dd9ed2c.jpg?v=1773999365","url":"https:\/\/aurosan-shop.de\/en\/products\/ph-fix-7-9-9-8-indikatorstabchen-6x85mm-10x100st","provider":"aurosan-shop.de","version":"1.0","type":"link"}
