一般描述

Trizma® 碱是在严格条件下以最高精度分析生产的容量法滴定标准品。其含量通过使用组合pH玻璃电极的体积中和滴定法测定。标准品的认证值和不确定性测量满足 ISO 指南 35 的要求。

应用

其可作为标准物质,用于在酸量滴定法标定滴定溶液。

特点和优势

  • 以坚固玻璃瓶装固体形式提供,确保开封前整个保质期内的稳定性。
  • 高纯度材料,可追溯至 NIST SRM
  • 高品质材料,可提供精准的滴定测定
  • 随附分析证书(CoA)

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。

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°C,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。
