Description
N 61eis is a pH electrode designed specifically for titrations performed in non-aqueous media. It incorporates a glass shaft, a triple platinum diaphragm, L 5014 electrolyte and an Ag/AgCl reference system, finished with a spherical A-glass membrane. The sensor measures 170 mm in length and 12 mm in diameter, covers the pH range 0 to 14 and is rated for operation between +10 and +40 °C. The triple platinum diaphragm ensures low junction potential and stable readings even in challenging organic solvents. These design features make the electrode suitable for non-aqueous titration methods used in pharmaceutical, chemical and quality-control laboratories. Offered as a single piece from manufacturer SI Analytics – a Xylem brand, the electrode combines proven glass chemistry with a compact form factor that fits standard titration vessels. Its defined temperature window and full-range pH capability support reproducible endpoint detection across a variety of non-aqueous sample types.

Questions about N 61eis, pH electrode for titrations in non-aqueous media with glass shaft, 3 x
What is this article?
N 61eis, pH electrode for titrations in non-aqueous media with glass shaft, 3 x is the article on this page. Luminix Health distributes SI Analytics - a Xylem brand for laboratory use. It sits in Burettes, inside Volumetric glassware, in Labware.
A burette delivers a measured volume through a stopcock, which is how a titration is read. Class A and class AS state the tolerance. The stopcock, glass or PTFE, and the volume of the burette are the choices. A dirty bore changes the delivered volume.
Volumetric glassware is glass that has been calibrated to contain or to deliver one stated volume at a reference temperature. That calibration is the whole point. Class A and class AS have a tighter tolerance than class B. A volumetric flask contains. A pipette and a burette deliver. A measuring cylinder is the coarser reading, used when the volume is not the result. The classes sit under ISO laboratory glassware. The chain back to the unit of volume is the work of the BIPM and of NIST.
