PH buffer solutions in sachets

PH calibration buffer solutions in 20 ml sachets are the ideal choice for those who want a product that is reliable, stable over time and conforms to the highest manufacturing standards. Each package contains 25 sachets with pH values ranging from 4.01 to 10.01, perfect for calibrating all types of portable or laboratory pH meters.

Manufactured to ISO 3693 / BS3978 standards, these solutions are produced using pure salts, deionised water and certified measuring instruments. Production takes place in temperature-controlled environments using certified thermometers, ensuring maximum accuracy and repeatability of measurements.

Each pH value is guaranteed to be accurate to ±0.01 pH at 25°C and fully traceable to NIST standards, making them suitable for professional, industrial and laboratory applications.

These sachets are particularly suitable for users who do not perform frequent calibrations, as each sachet is perfectly sealed to keep the value stable until use. In addition, the solution contains no dyes, avoiding the risk of staining the junction or the electrode reference cell.

Each sachet carries a lot number and expiry date, information that is essential for traceability and proper calibration management. The sachets can last up to 5 years if unopened, while the outer packaging protects the contents from UV rays that can alter the stability of the pad.
