Full Description

The HI-93710-01 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. These reagents follow the Phenol Red method in which the reagents produce a range of colour that is pH-dependent. By simply adding 5 drops from the bottle of reagent to the sample, the reaction between the sample and reagent causes a tint in the sample that varies from yellow to red. The intensity of colour is determined by a compatible photometer and the concentration will be displayed. The results will be displayed in pH units with a resolution of 0.1 pH. These reagents are designed to be used with samples that have an expected range of 6.5 to 8.5 pH.

Tip for an accurate measurement

It is important that the sample does not contain any debris.

When the cuvette is placed into the measurement cell, it must be dry outside and completely free of fingerprints, oil or dirt. Wipe it thoroughly with HI-731318 or a lint-free cloth prior to insertion.

Shaking the cuvette can generate bubbles, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the cuvette.

Do not let the reacted sample stand for too long after reagent is added, or accuracy will be lost.

After the reading, it is important to discard the sample immediately, otherwise the glass might become permanently stained.
