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
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.

Analysis Note
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
所有缓冲液的 pH 值与温度和浓度都有关。对于 Tris 缓冲液，温度每降低 1°C，pH 增加约 0.03 个单位，浓度每稀释 10 倍，pH 降低 0.03-0.05 个单位。 对于精确应用，使用带有玻璃/甘汞复合电极的经仔细校正的 pH 计。
