Buffer Solutions (e.g., Phosphate Buffered Saline, Tris Buffer)
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Buffer solutions, such as phosphate-buffered saline (PBS) and Tris buffer, are aqueous solutions that maintain a stable pH when small amounts of acids or bases are added. They are widely used in biological and chemical experiments to provide a consistent environment for reactions, assays, and cell cultures. These buffers play a crucial role in ensuring accurate results by preventing pH fluctuations that could affect biological activity or chemical stability.
