The expanded uncertainty (k=2) due to weighing, volumetric preparation and homogeneity is calculated in compliance with EURACHEM/CITAC Guide: Quantifying Uncertainty in Analytical Measurements as ±2.5%.

TRACEABILITY IN THE PRODUCTION OF THIS STANDARD

This product was prepared gravimetrically on a weight/volume basis. The solute was weighed on a balance calibrated by Reagecon engineers using OIML traceable weights. Reagecon holds ISO 17025 accreditation for calibration of non-automatic weighing machines (265C). The resulting Balance Certificate of Calibration was issued in accordance with the requirements of ISO/IEC 17025. The balance was calibrated under monitored environmental conditions and atmospheric pressure. Tests were performed for capacity, readability, repeatability, eccentricity and linearity. Dilution of the final product to volume was performed using internally calibrated Class A volumetric glassware.

STORAGE/USAGE INSTRUCTIONS:

Please store this product in a freezer (<-15°C). To open product, invert at least 10 times (do not shake) and sonicate if solid material is apparent. Break the ampoule open at the lower neck mark (caution: sharp glass) and transfer to vial. Allow to return to room temperature before use. Store after opening in a freezer. Invert, sonicate and allow vial to return to room temperature before each subsequent use. Use only Class A volumetric glassware for dilutions and ensuring thorough mixing.
