In tegenstelling tot conventionele indicatorpapieren zijn de indicatorkleurstoffen van pH-Fix-sticks substantieel gebonden aan de cellulosevezels (DE-PS 24 36 257). Hierdoor wordt de mogelijkheid van kleurbloeding, zelfs in sterk basale oplossingen, vermeden.
Gebruiksaanwijzing
Verwijder een teststrip uit de verpakking, dompel de strip in de oplossing of vloeistof die wordt getest, vergelijk de kleurverandering op de strip met de kleurenkaart op de verpakking om de pH-waarde te bepalen

These pH-Fix testing strips from Macherey-Nagel measure the range from 6.0 to 10.0. There are other versions of this product that test other ranges of pH value, all the way from 0 to 14, to others that focus on specific ranges, some of which are for medical purposes. I experienced some uncertainty when aligning my test strips with the reference values that are printed on the packaging. Each testing strip is 84mm long and made of plastic so you can do your best to avoid touching the chemical that you are testing. This is obviously important for strong acids and alkalines but not particularly important for the relatively weak range that these strips test. But in any case you don't want to be contaminating your sample by touching it.These testing strips cost about three times as much as others you can get on Amazon. That's quite a difference for a seemingly similar product.

As a nutritionist I encourage people to alkalise their diet as much as possible. These test strips are vital for testing the ph of their urine to see how the alkalising of the body is going. any illness are from having an acid diet and body and alkalising is a great benefit. These strips are perfect and give the mid range of the ph . These strips work perfectly and give a correct indication ot the acidity or alaclinity of your system .They are great to have.
