Indicator papers to check the pH value quickly and easily directly in the solution of
interest.
Used in analytical chemistry, they are immersed or placed in contact with the sample to be analyzed in order to know it
acidity or alkalinity.
The maps are ready to use with no need for calibration, preparation or maintenance. Therefore the
pH determination is really simple, regardless of experience and chemical background of
each.
The plastic handle of the strip protects against the possibility of direct contact with the sample,
thus allowing to work with toxic, dangerous or aggressive substances in complete safety.
