LF Standard 1413 µS/cm is a conductivity calibration standard supplied in single-use seal-edge pouches for laboratory sensor work. Each package contains 30 pouches of 20 mL, giving a practical stock of fresh aliquots for routine checks without opening a bulk bottle. The defined conductivity value of 1413 µS/cm supports adjustment and verification of conductivity sensors in analytical, quality-control and process environments. NIST traceability links the reference value to recognised metrological standards, and a quality certificate accompanies the product. Seal-edge pouch packaging protects the solution until the moment of use and simplifies clean handling at the bench. Laboratories can build the pouches into regular maintenance schedules for conductivity measurement systems and reduce contamination risk compared with repeatedly opened containers. This standard from manufacturer Mettler-Toledo OnLine is delivered as one complete package with a gross weight of 0,77 kg. The single-dose format helps preserve solution integrity between successive calibrations and fits everyday laboratory material workflows where reliable conductivity references are required.
This article belongs on pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Cond stand. 1413 uS/cm, sachets 30x20mL
What is this article?
Cond stand. 1413 uS/cm, 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 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.
