WD-35850-12 Buffer Capsules, pH 4; 10/Pk by Oakton
Buffer salts inside capsules require 100 mL of deionized or distilled water to produce a clear pH calibration solution accurate to ±0.02 pH (at 25°C) with traceability to NIST standards. Capsules are easier to store and transport than prepared aqueous buffer solutions. Capsules are color-coded for easy identification if mixed.
Store buffer solution in an airtight container at room temperature for three weeks. Unused capsules have a five-year shelf life. Each vial contains 10 capsules.
Fresh pH calibration solution anytime and anywhere
- Each capsule mixes with 100-mL of deionized water to create a clear, 4.00 pH solution
Includes
Ten red-colored capsules.
