Key Components

Bis Tris Buffer Recipe: The key components of this buffer include Bis and Tris as the buffering agents. Bis, also known as bis-tris, is a zwitterionic organic compound that maintains a stable pH in the buffer. Tris, or trishydroxymethylaminomethane, acts as a buffering agent with its neutralizing properties. It helps to maintain the stability of the pH level in the buffer solution.

Preparation And Recipe

Bis Tris buffer is commonly used in the laboratory for a variety of applications. Here is a simple recipe for preparing Bis Tris buffer:

Ingredients:

  • Bis Tris: This is the main component of the buffer solution.
  • Phosphoric acid: Used to adjust the pH of the buffer.
  • Sodium hydroxide: Also used for pH adjustment.
  • Distilled water: Used as the solvent for the buffer.

Step-by-step Instructions:

  1. Determine the desired final volume of the buffer solution.
  2. Calculate the amount of Bis Tris needed based on the concentration desired.
  3. Measure and add the appropriate amount of Bis Tris to a clean glass beaker.
  4. Add a small amount of distilled water to dissolve the Bis Tris completely.
  5. Slowly add phosphoric acid or sodium hydroxide to adjust the pH, using pH paper or a pH meter to monitor the pH level.
  6. Once the pH is adjusted, add distilled water to reach the desired final volume, while continuously stirring the solution.
  7. Transfer the buffer solution to a clean storage container and label it appropriately.
