일반 설명
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.
애플리케이션
It finds its use as a reference material for the standardization of volumetric solutions in acidimetric titrations.
특징 및 장점
- 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)

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.
기타 정보
The pH values of all buffers are temperature- and concentration-dependent. For Tris buffers, pH increases about 0.03 unit per °C decrease in temperature, and decreases 0.03-0.05 unit per ten-fold dilution.
For precise applications, use a carefully calibrated pH meter with a glass/calomel combination electrode.
