Corning® Pyrex® Economy Volumetric Flasks with ST StopperBy Corning
These Pyrex® economy flasks are designed for those that do not require the precision accuracy of Class A capacity flasks. Capacity tolerances are twice those specified for Class A volumetric ware. The graduation line is sharp and permanent; large white block letters make inscriptions easy to read. Supplied with ST glass stoppers. For replacement stoppers see Cat.No. 1-7650.
