Pipes have the meanings of pipes, pipes, wind instruments, etc. when translated into Chinese, so what is pipes buffer? It specifically refers to a buffer that can adjust the pH value of the experimental liquid, abbreviated as 1-4-piperazine diethyl sulfonic acid. It is an amphoteric buffer with a white crystalline powder appearance that needs to be prepared into a solution when used. 1. The characteristics of pipes Pipes cannot be dissolved in water, they are soluble in sodium hydroxide aqueous solution; The buffer range is between 7.2 and 7.4; The chemical properties are relatively stable and do not undergo chemical reactions with most metal ions. 2. Advantages of Pipes Pipes have a low UV absorption range of λ≥ 260 nm; The Pka value is less affected by temperature changes; Strong solubility in sodium hydroxide aqueous solution; Low response to interference received; The steps for preparing a solution are simple. 3. Application of Pipes Pipes are widely used for metal ion buffer solutions and cell culture work; When the concentration of pipes is low, it is suitable for cation exchange chromatography; It can also be used for immunofluorescence reaction and localization of urate oxidase ultrastructure in mouse liver peroxisomes. 4. Preparation method of Pipes When preparing pipes powder into a solution, deionized water and sodium hydroxide are required. First, dissolve 4 grams of sodium hydroxide in 400 grams of deionized water, add 30.237 grams of pipes powder, stir to completely dissolve, and then add deionized water to a constant volume of 1000 milliliters. 5. Precautions for saving pipes When storing Pipes powder, it is necessary to pay attention to avoiding light and moisture, and store it in a ventilated and cool place for better results; Pipes solution is sensitive to light, so choosing a dark container for storage has a smaller impact on the effectiveness of use when ready to use.
