Tris HCl buffer is a commonly used buffer in biochemical experiments to stabilize the pH value. Due to its original state as a powder, many laboratories or manufacturers prepare it into a solution during use. Compared to powder, the solution is more susceptible to external influences, so there are certain limitations on its preparation and storage. This also makes many people doubt whether the prepared solution must be ready to use. Next, we will analyze this issue specifically for everyone.
1、 Tris HCl buffer powder
Due to the stable buffering effect provided by Tris HCl over a wide pH range, it is suitable for biochemical and molecular biology experiments. At the same time, due to its high water solubility, only deionized water needs to be used to prepare a buffer solution with the required concentration.
2、 Tris HCl powder storage
Tris HCl has good stability within an appropriate pH range. If storage conditions are improper or exceed its stable range, the pH value will change, leading to poor buffering performance. Therefore, in response to this situation, the storage of Tris HCl powder has become extremely important. The optimal storage method is to store it in a dry and sealed container, avoiding moisture absorption and exposure to the air, while keeping it away from direct sunlight to avoid excessive temperature.
3、 Tris HCl powder ready to use
In order to ensure stable performance of Tris HCl buffer, it is necessary to prepare and use it immediately. Powder is susceptible to external interference, and of course, the solution is no exception. As it has been prepared, long-term storage can easily breed bacteria. If stored improperly, it can also cause the solution to deteriorate and produce a pungent odor, which not only wastes raw materials but also affects the experimental process. Furthermore, the solution is affected by thermal stability, and after being prepared, it is prone to degradation after multiple openings, resulting in ineffective buffering performance.
To ensure the reliability of the experimental results, everyone must pay attention to ready-to-use and use according to the experimental operating standards. Of course, the prerequisite for using Tris HCl is the reliability of product quality. If Tris HCl itself is not reliable, it is not necessary to pay attention to storage methods and preparation details.
