Trizma® base is a volumetric standard produced under rigorous conditions and measured with the highest possible precision. Its content is determined by volumetric neutralization titration using a combined pH glass electrode. The certified value and uncertainty measurement of the standard are in accordance with ISO Guide 35.
Application
It finds its use as a reference material for the standardization of volumetric solutions in acidimetric titrations.
Features and Benefits
- Available as a solid in a secure glass bottle to ensure its stability for the entire shelf life until opened.
- High-purity material traceable to NIST SRM
- High-quality offering accurate titer determinations
- Accompanied by a certificate of analysis (CoA)
Analysis Note
Exact concentration, expiry date, traceability and detailed information on certification can be found on the certificate and certification report, included in each package. Content and expiry date on label.
Other Notes
Le pH de tous les tampons dépend de la température et de la concentration. Pour les tampons Tris, le pH augmente de 0,03 unité pour chaque 1 °C de réduction de température, et diminue de 0,03-0,05 unité par dilution d′un facteur dix.
Pour les applications précises, utiliser un pH-mètre soigneusement calibré avec une électrode de verre au calomel.

A new water-soluble, multisite-coordinating ligand LH(7) was prepared by the condensation of tris(hydroxymethyl)aminomethane with 2,6-diformyl-p-cresol. LH(7) is a selective chemosensor for Cu(2+), under physiological conditions, with visual detection limits of 20 ppm (ambient light conditions) and 4 ppm (UV light
