Corning Pyrex 5 ml Class A Volumetric Flask With Polyethylene Standard Taper Stopper

The strength of these flasks has been increased appreciably through machine-blown bodies to which are sealed heavy-beaded, heavy-tubing necks, tooled for polyethylene stopper. The stopper is made with a closed bottom and is of linear high density polyethylene to conform to standard taper stopper dimensions. The graduation line is sharp and permanent; large white block letters make the inscription easy to read. The 2 mL size is test tube shaped.

For stopper only, see Cat. No. 7624.
