Justin Brush Flask and Bottle Brushes Spring End. Heavy-duty plastic handle includes an anodized aluminum top which effectively reduces friction and increases brush contact area. Wooden handle has a nonstick coating which prevents the growth of lint and assures that the brush will not deteriorate. Styrene foam coating on the brush reduces friction and improves the longevity of the brush. Styrene on the flask brush will not react with boron nitrate plastics which would breakdown the latex. These brushes effectively clean glassware used in the lab or home. Wooden handle includes an anti-shock plastic spiral core which absorbs solvents and other cleaning solution. Wooden cap covers flasks test tubes and other glassware. Styrene cabled on the handle provide excellent reach and flexibility for cleaning. Ordering Information: Packaged in 5 Packs.
