Sampling Bottles Comprehensive Guide: Materials, Classification and Application Scenarios 1. Overview of Sampling Bottles Sampling bottles are specialized containers designed for the collection, temporary storage, and transportation of various samples, which are engineered to maintain the physical, chemical, and biological properties of samples unchanged during the handling process. Unlike ordinary containers (such as glass cups, plastic bottles), sampling bottles have strict requirements for material purity, sealing performance, chemical compatibility, and sterility, to avoid sample contamination, component loss, or chemical reactions between the container and the sample. The core functions of sampling bottles include three aspects: sample protection (isolating external factors such as air, moisture, light, and microorganisms to prevent sample degradation, oxidation, or contamination), operational safety (preventing sample leakage, volatilization, or operator exposure to ...
