Hydrion Tri-Chek Buffer Set
The Hydrion Tri-Chek Buffer Capsule set is perfect for easy and quick pH meter calibration. When mixed with de-ionized or distilled water, they will accurately produce 100 ml of solution at pH 4.00, 7.00, and 10.00. Hydrion Buffers are free flowing soluble powders that prepare color safe solutions in minutes.
The set contains 1 vial of each buffer standard. Each vial contains 10 capsules. Each capsule produces 100ml of solution. 1 vial of Hydrion Color Key Buffer Preservative which prolongs the shelf life of the solution and automatically tints each solution to its own color value: orange for ph 4.00, green for ph 7.0 and blue for ph 10.0, is included in the set.
Directions: Empty the contents of a buffer capsule into 100 ml of de-ionized or distilled water. If desired, to extend shelf life, add 3 drops of Hydrion Buffer Preservative per 100 ml of buffer solution and mix thoroughly.
