Tris includes a pKa of 8.1 so Tris buffer is created at pH 7 to pH 9. You are able to prepare this buffer at any concentration and then any volume and employ it to avoid large swings within the pH of the solution.
Tris Buffer Materials
- TRIS powder
- muriatic acidity
- sterilized water
- pH meter
- glasses
How you can Prepare Tris Buffer
- You have to figure out what concentration (molarity) and amount of Tris buffer you need to make. After you have made the decision what you're making, calculate the amount of moles of Tris which are needed by multiplying the molar power of buffer by the level of buffer being made.
moles of Tris = mol/L x L

- Next, determine the number of grams of Tris this really is by multiplying the amount of moles through the molecular weight of Tris(121.14 g/mol).
grams of Tris = (moles) x (121.14 g/mol)
