关于该商品的更多信息

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.
