How much powder is required for Bicine buffer preparation

Release time:


Bicine is an important chemical buffer widely used in biology, medicine, and chemical experiments. As a high-quality buffer, Bicine buffer has many unique advantages, such as high stability, high pH buffering range, and good ion strength. However, when using Bicine buffer, we need to know how to properly prepare it, especially how much powder is needed. Below, we will discuss in detail the Bicine buffer and the required amount of powder.

Bicine powder

Characteristics of Bicine buffer solution

1. High stability: Bicine buffer has high stability and can maintain a stable pH value over a wide range of pH, making it an ideal choice for many experiments that require long-term pH stability.

2. High pH buffering range: Bicine buffer has a very wide pH buffering range, ranging from pH 7.6 to pH 9, which can adapt to various experimental conditions and meet the needs of different pH values.

3. Good ion strength: Bicine buffer has good ion strength, which can effectively maintain ion balance in the solution and accurately control the experimental ion concentration.

The required amount of powder for Bicine buffer solution

When using Bicine buffer, we need to know how to properly prepare it, especially how much powder is needed. Generally speaking, the concentration of Bicine buffer solution depends on the specific requirements of the experiment. We can calculate the required amount of Bicine powder using the following formula:

Required powder amount (mg)=target concentration (mM) × Solution volume (mL)/1000

Among them, the target concentration refers to the concentration of Bicine buffer you want to obtain, and the solution volume refers to the volume of solution you need to prepare. This formula can help you determine the required amount of Bicine powder. However, it should be noted that this formula is only a general calculation method, and the actual required amount of powder may vary depending on the specific needs and conditions of the experiment. Therefore, in practical use, adjustments may need to be made according to the specific situation of the experiment.

Preparation method of Bicine buffer solution

Material preparation:

Bicine powder, distilled water, high-precision pH meter, NaOH or HCl (used to adjust pH)


1. Weighing Bicine powder: According to the required concentration and volume, weigh an appropriate amount of Bicine powder. Generally, the optimal concentration range for Bicine is 0.01 M-0.5 M.

2. Add distilled water: Slowly add Bicine powder to a container and add an appropriate amount of distilled water. Stir and dissolve until Bicine is completely dissolved.

3. PH adjustment: Use a high-precision pH meter to detect the pH value of the solution. If necessary, add NaOH or HCl dropwise until the target pH is reached. Note that the pKa of Bicine is approximately 8.3, so adjusting the pH should take into account the exact pH range required for the experiment.

4. Volume adjustment: Adjust the total volume of the solution with distilled water to ensure that the concentration and volume meet the experimental requirements.

Precautions for using Bicine buffer solution

1. Storage: Bicine buffer should be stored in a dry, cool, and dark place, avoiding mixing with strong acids, bases, and other substances. At the same time, it should be sealed and stored to prevent deliquescence and spoilage.

2. Usage: It should be prepared according to the specified concentration and proportion to avoid excessive use or high concentration, so as not to affect the experimental results. Meanwhile, use the correct pH range to ensure accurate experimental results.

3. Safety: Bicine buffer has a certain degree of irritancy, avoiding direct contact with skin and eyes. When operating, protective equipment such as gloves, masks, etc. should be worn.
