PL A micro pestle is a small laboratory tool used for grinding and homogenizing samples in microcentrifuge tubes. It is typically made of plastic or glass, ensuring durability and chemical resistance. The design allows efficient crushing of tissues, cells, or small solid samples. It fits perfectly into microtubes for easy and precise sample processing. Micro pestles are commonly used in molecular biology and biochemical experiments. They are easy to handle, lightweight, and often disposable or reusable. This tool is essential for sample preparation in research and diagnostic laboratories.
