Storage methods and requirements for trimethylaminomethane

 

Trimethylolaminomethane, also known as Tris, has a chemical CAS number of 77-86-1, and is a commonly used biological buffer in the fields of bioscience and industrial chemistry. It is widely used in biopharmaceuticals, in vitro diagnostics, cosmetics, and architectural coatings.

 

Tris is used to adjust the pH value of the solvent, effectively adjusting the range of acid base between 7-9, and playing a role in neutralizing and stabilizing the acid base value of the reagent. The appearance is white crystalline powder, easily soluble in water. In the process of use, we usually configure it as a solution because it is relatively sensitive to temperature environments, so how to properly store the prepared solution has become a difficult problem. Let's take a brief look below.

 

When tris is in a crystalline powder state, it is necessary to pay attention to moisture prevention and must be stored in a dry, cool, and ventilated location. If the sample is opened, it is necessary to seal it as soon as possible. After tris is configured as a solution, it is greatly affected by temperature, and temperature differences can lead to changes in its pH value. Generally, it is recommended to store in a 4-degree refrigerator, which can also be stored at room temperature, or frozen at - 20 degrees. The temperature requirements for powder storage are not too high, but when preparing a solution, special attention should be paid to the ambient temperature:

 

"For example, the pH of the buffer solution at 4 ℃ is 8.4, while the pH at 37 ℃ is 7.4. For solutions prepared at different temperature conditions, the temperature requirements for use scenarios vary.". If it is necessary to configure a buffer solution that can only be used under a specific temperature environment, configure it according to the measurement temperature requirements.

 

"Because tris is prone to react with carbon dioxide in the air, the prepared buffer solution needs to be sealed and stored.".

 

Some PH electrodes may interfere with Tris buffer solution, so it is necessary to select electrodes compatible with this buffer solution.

Before use, it is also necessary to check whether the solution has any turbid or flocculent matter. If so, it cannot be used again.
