Sample Preservation

Sample preservation refers to the methods used to protect biological, environmental, or material samples from degradation or contamination after they are collected. Proper preservation ensures that the samples maintain their integrity, composition, and reliability for tests and analysis. Techniques can include refrigeration, freezing, drying, or using preservatives. The goal is to keep the samples as close as possible to their original state, allowing for accurate results when studied, whether in a laboratory, research, or medical context. Good preservation practices are critical for obtaining valid and trustworthy data.
