LabChem® Fluoride Standard, 0.5ppm W/TISAB

LabChem® FLUORIDE STANDARD, 0.5ppm w/TISAB is a certified fluoride ion calibration standard at 0.5ppm, pre-mixed with TISAB (Total Ionic Strength Adjustment Buffer). The TISAB component adjusts and equalizes ionic strength, buffers pH, and complexes interfering ions such as aluminum and iron so the fluoride ion-selective electrode reads free fluoride activity accurately. This ready-to-use formulation removes the need to prepare and add TISAB separately.

It is commonly used to calibrate and verify fluoride ion-selective electrode (ISE) meters before sample analysis, including drinking water, wastewater, and dental product testing. Its certified concentration supports consistent, dependable calibration curves across testing sessions. This reagent should be handled, stored, and used according to established laboratory safety procedures and the manufacturer's instructions.
