Stir bars and retrievers are laboratory tools designed to support efficient mixing and safe handling of magnetic stir bars. Stir bars, typically coated in PTFE (or Teflon) for chemical resistance, enable consistent and uniform stirring of liquids in beakers, flasks and other vessels, while retrievers allow for easy and safe removal of stir bars without contaminating the sample. Suitable for research, industrial, quality and teaching laboratories, these tools provide reliable performance for routine and precise laboratory workflows.
