Description
Buffer solution, technical grade, pH 9,00 is a ready-to-use alkaline calibration standard for precise pH meter and electrode adjustment. Each single-use sachet contains 20 ml of buffer with a tolerance of ±0,01 pH, delivering a stable alkaline reference for everyday laboratory calibration. The pack comprises 25 sachets of 20 ml, offering a clean unit-dose presentation that reduces cross-contamination and evaporation risks associated with shared bottles. Manufactured to technical quality and supplied with a certificate of analysis, the solution is traceable to NIST standards. This buffer from manufacturer Hanna Instruments supports quality-control, environmental, food, beverage, water-treatment and educational applications that require a dependable pH 9,00 calibration point. Sealed sachets keep the solution protected until opened and streamline workflows for technicians performing frequent calibrations. Net pack weight is 0,65 kg (gross weight 1,65 kg). The convenient sachet format is well suited to laboratories that need documented technical-grade alkaline pH buffers in practical single-use portions.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about 9.00 pH Value @25°C, (25) 20 mL sachets
What is this article?
9.00 pH Value @25°C, (25) 20 mL sachets is the article on this page. Luminix Health distributes Hanna Instruments for laboratory use. It sits in pH buffers & conductivity standards, inside Buffers & pH solutions, in Lab chemicals.
A pH buffer for calibration has a stated pH at a stated temperature, often traceable. A conductivity standard has a stated conductivity. They are not general reagents and they should not be poured back into the bottle. The temperature of the measurement has to be the temperature on the label, or the meter has to compensate.
A buffer resists a change in pH when a little acid or base is added. It does that because a weak acid and its conjugate base are both present. A pH buffer used to calibrate a meter has a stated value at a stated temperature. A biological buffer such as Tris or HEPES is chosen because it holds the pH of a living system and does not poison it. Conductivity standards are the sister articles for a conductivity meter. The ions are on PubChem. Electrode calibration practice sits with EURAMET and BELAC.
