Calibration solution set pH 4,01/7,00/10,01 + 3M KCl with Calbox provides a complete ready-to-use system for multi-point pH calibration and electrode maintenance. The set includes four 250 ml bottles—pH 4,01, pH 7,00, pH 10,01 buffers and 3M KCl storage solution—plus a sealable Calbox that holds up to four solutions and simplifies every calibration step. Accuracy of pH 0,015 supports highly precise three-point calibration. Colour coding ensures rapid identification: pH 4,01 red, pH 7,00 green and pH 10,01 blue. The 3M KCl solution preserves the sensitivity and accuracy of pH and ORP electrodes. All buffers are liquid and can be used immediately without dissolving powders. Traceable to NIST standards, the kit delivers reliable reference values. Supplied as a 1-set pack with a net weight of 1,0 kg from manufacturer APERA Instruments, it combines long shelf life, online batch certificates and the practical Calbox for organised laboratory workflows in research, quality control and process monitoring.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Calibration Solution Set pH 4.01 / 7.00 / 10.01 + 3M KCl (250ml each) + Calbox
What is this article?
Calibration Solution Set pH 4.01 / 7.00 / 10.01 + 3M KCl (250ml each) + Calbox is the article on this page. Luminix Health distributes APERA Instruments for laboratory use. It sits in pH buffers & conductivity standards, inside Buffers & pH solutions, in Chemicaliën.
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.
