General description【一般描述】
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【应用】
It finds its use as a certified reference material (CRM) for the standardization of volumetric solutions in acidimetric titrations.
Features and Benefits【特点和优势】
  • 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【分析说明】
精确浓度、有效期、可溯源性以及详细认证信息,请见每个包装内的证书和认证报告。标签上标明含量和有效期。
Other Notes【其他说明】
所有缓冲液的 pH 值都取决于温度和浓度。Tris 缓冲液,温度每降低 1℃,pH 值增加约 0.03 个单位,每稀释十倍 pH 值降低0.03-0.05 个单位。
对于精确的应用,使用经过精心校准的 pH 计和玻璃/甘汞组合电极。
