The rigid plastic sticks measure 85 mm (length) x 6 mm (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 strongly alkaline or weak buffer solutions. When testing pH, the strips produce a permanent color change, even when left in place, e.g., when testing solutions of low ionic strength. An immediate result is obtained by color matching the four test zones with the enclosed pH color chart. The pH color chart accurately matches both the color and position of the pads on the strips. Results are easy to interpret and can be reliably determined, as the pH gradations are in 0.3 increments. The pH indicator sticks are suitable for many applications, both in the laboratory and in the field. They have the advantage over other pH measurement methods that they require no additional equipment compared to liquid test kits and digital meters. This makes them more portable, durable, and easily replaceable. The pH indicator sticks come 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":57032361017676,"sku":"MD-AL-01848","price":19.46,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/1056\/9036\/files\/BC_Upload_e2d6a0d0-e6e6-464f-8508-8a9a6763b4c2.jpg?v=1773999361","url":"https:\/\/aurosan-shop.de\/en\/products\/ph-fix-5-1-7-2-indikatorstabchen-6x85mm-100-st","provider":"aurosan-shop.de","version":"1.0","type":"link"}
