Buffers
Resisting pH changes, buffers protect samples when acids or alkali is added. Powder and liquid forms efficiently track proteins during electrophoresis isolation and separation. The salty buffers can also be used to calibrate and standardize pH meters for accurate readings. Blocking substances stop antibody attachment to membrane free sites that would produce an interfering background. In various concentrations to fit any need, the buffers may come in liquids or dehydrated formats.

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.
