Micro-vials are small containers or vials designed to hold very small volumes of liquid or samples. They are typically used in scientific research, medical diagnostics, and pharmaceutical industries, where precise and accurate measurements of small quantities of substances are required.Micro-vials are commonly made from materials such as glass or plastic, depending on the specific application. They are designed to be airtight and leak-proof to prevent contamination or loss of the sample. The vials often have a small opening or cap that allows for controlled dispensing or extraction of the liquid or sample.
