microsyringe

A microsyringe is a specialized syringe designed for dispensing very small, precise volumes of liquids, typically in the microliter range. It is characterized by its fine scale markings and a plunger that moves with extreme accuracy, allowing for reproducible measurements. The barrel of a microsyringe is usually made of glass or plastic and has a very narrow internal diameter. The needle is also very fine, often with a point that is beveled at a specific angle to minimize liquid displacement upon insertion.

Microsyringes are widely used in various scientific and technical fields where precise liquid handling is critical. Common applications include gas chromatography, where they are used to inject samples onto the column, and in liquid chromatography. They are also employed in molecular biology for tasks such as DNA and RNA manipulation, in chemistry for titrations and sample preparation, and in medicine for administering minute doses of drugs or for sampling biological fluids. The design and calibration of microsyringes are crucial for ensuring accuracy and reliability in experimental results. Different types of microsyringes exist, including fixed-needle and interchangeable-needle models, and those with specialized plungers for specific applications.
