These quality glass test tubes are made from borosilicatae glass. Borosilicate glass offers excellent durability and chemical resistance while also reducing pH changes and contaminants that are potentially leached from tubes made from soda lime glass. Six popular sizes are available. The bottoms of the tubes are uniform and rims are fire-polished. Packaging is neat with 250 tubes per box. They are shrink-wrapped in film to help keep them particle free.
