Pyrex® 50ML class b volumetric flask, tooled neck
PYREX 50mL Class B Volumetric Flask, Tooled Neck
PYREX economy flasks are designed for use in applications 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. Heavy duty necks are tooled for polyethylene snap-caps.
