pH Calibration Buffers
The pH buffers are essential for routine pH meter calibration to capture accurate pH range of acid or base. Ready-to-use prepared solutions eliminate the time, expense, and contamination risks of mixing buffers. pH buffers can be used to identify weak acid, conjugate base, strong acid, blood pH etc. With colored and colorless pH buffer options available, researchers can efficiently select the correct indicating solution for any test. Powder pillows and sachets permit laboratories to store the concentrated substances for longer time periods without being affected.

Vernier® pH Buffer Capsules, 3×10
The pH Buffer Capsules (3x10) kit is a convenient set of three vials containing capsules to make pH 4, pH 7, and pH 10 buffer standards for calibrating pH sensors. Each vial contains 10 capsules, each of which produces 100 mL of solution when mixed with DI water. Add three drops of the buffer preservative to 100 mL of your buffer solution to prolong the shelf life. Hydrion Color Key Buffer Preservative is a combination mold inhibitor and universal indicator for color coding the buffer solutions: orange for pH 4, green for pH 7, and blue for pH 10.
