Description
Technical buffer solution pH 2,00 is a ready-to-use standard for pH meter calibration, filled in single-use sachets for clean, portion-controlled handling. Each sealed sachet holds 20 ml of technical-grade buffer with a stated value of pH 2,00 ±0,01 at 25 °C, supporting consistent electrode checks in routine laboratory and technical workflows. The pack contains 25 sachets, so a fresh aliquot can be opened for every calibration and unused solution is not returned to a bulk bottle. Traceability is referenced to NIST, and each pack is supplied with a certificate of analysis to document the stated pH value. This format from manufacturer Hanna Instruments suits multi-user benches, field kits and quality-control stations where contamination control and simple stock rotation matter. Net weight is 0,624 kg (gross 1,624 kg), reflecting the full carton of sachets. The technical grade addresses everyday calibration needs without unnecessary complexity, while the sachet presentation keeps preparation fast and reduces cross-contamination risk between measurements.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about pH 2.00 Technical Calibration Buffer Sachets (25 x 20mL)
What is this article?
pH 2.00 Technical Calibration Buffer Sachets (25 x 20mL) 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.
