설명

애플리케이션

Open the foil pouch, dissolve contents in 900 mL of water; add additional water to a final volume of 1 liter to make a 0.1 M solution at a temperature of 25 °C. 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.
