Application
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.
The product is cell culture tested. It is also tested for low endotoxin levels and analyzed for the absence of nucleases and proteases.
