Tri-Chek pH Buffer Sets - Hydrion*
TRI-CHEK Buffer Sets provide calibrated and pre-weighed amounts of buffer
powders at three pH values pH 4.0, 7.0, and 10.0. A correctly calibrated pH
meter will check all three points. This set furnishes the materials needed for
reliable pH meter standardization and verification.
The buffer powders in the package are stable and will keep indefinitely. The
powders dissolve rapidly in water to give fresh reliable standards in just a few
The Color Keyed Buffer Preservative, included in the sets will prolong the
useful life of the solution. A few drops of this preservative added to the
buffer solutions is an effective mold inhibitor and automatically tints each
solution to its own value color.
