Description
Buffer pH=7.00 supplied in sealed-edge sachets is a ready-to-use calibration solution for pH sensors. The pack contains 30 individual sachets of 20 ml each (30 × 20 ml), giving convenient single-use portions for bench or field work. At 25 °C the buffer value is 7,00 pH with an accuracy of ±0,02 pH, supporting precise instrument adjustment around the neutral point. Traceability to NIST together with a quality certificate underpins documented calibration procedures in regulated and routine laboratories. The stated shelf life is 2 years. Sealed sachets help preserve solution integrity until the moment of use and limit cross-contamination relative to multi-dose containers. Intended for calibration of pH sensors, this format from manufacturer Mettler-Toledo OnLine suits laboratories and process environments that need a reliable neutral buffer in practical unit doses. The 30 × 20 ml configuration balances economy with freshness for frequent calibration schedules without opening large stock bottles.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Techn. Buffer pH 7.00 sachets 30x20mL
What is this article?
Techn. Buffer pH 7.00 sachets 30x20mL is the article on this page. Luminix Health distributes Mettler-Toledo OnLine 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.
