This 50 mL Schellbach burette features a vertical white backing with a central white line opposite the graduations, providing enhanced contrast with the meniscus for accurate readings. It is classified as Class B and manufactured from borosilicate glass with 0.1 mL white graduations. The Schellbach design significantly reduces parallax error in meniscus reading. The burette is suitable for titration and other volumetric analysis procedures in educational and analytical laboratories.
