说明

應用

Dissolve in water to make a 0.1M solution. No pH adjustment is necessary. Guaranteed accuracy: ±0.1 pH units.

Tris has a significant temperature coefficient, so select the mixture to give the desired final pH at the desired temperature.
From 5 °C to 25 °C, the pH decreases an average of 0.03 pH units per °C.
From 25 °C to 37 °C, the pH decreases an average of 0.025 pH units per °C.

If a different concentration is desired, note that there is a concentration effect on the pH of the solution.

该产品经细胞培养测试。它还经过了低内毒素水平检测并分析了是否已去除核酸酶和蛋白酶。

其他說明

This product is a pre-mixed combination of Trizma base and Trizma HCl that can be used to prepare a common pH value for Tris buffer.

某些pH电极不能使用Tris缓冲液提供准确的结果。
