High-Precision pH Standards for Analytical, Calibration, and Titration Applications
The VWR® Buffer Solution AVS Titrinorm series is a premium range of ISO 17034-certified buffer solutions formulated for laboratories requiring precise and traceable pH calibration. Manufactured from AnalaR® NORMAPUR® analytical-grade reagents, these buffers deliver exceptional accuracy with a precision of ±0.02 pH units (from pH 1.00 to 11.00) and ±0.05 pH units (at pH 12.00). Each buffer is traceable to Standard Reference Materials (SRM) from NIST and complies with international metrological standards, making it ideal for regulated environments including pharmaceutical, environmental, and quality control laboratories.
These solutions come in a wide selection of pH values and volumes, providing flexibility for pH meter calibration, titration standardization, and routine pH measurement workflows. Each bottle is labeled with a batch number and packing date, and Certificates of Analysis (CoA) are available upon request to support full regulatory compliance.
