The Pasteur pipette (225mm) is a staple laboratory tool widely manufactured in China for both high-precision and general transfer tasks. These pipettes are typically available in soda-lime glass or borosilicate glass variants, with the 225mm length being a standard industry size alongside the 150mm model.
