PYREX ® VISTA™ 2000 mL Class B, Volumetric Flask with Polyethylene Snap-Cap

(This is the suggested replacement for 5581-2L)

These 2000 mL PYREX VISTA™ flasks are designed for use by customers that do not require the precision accuracy of our Class A capacity flasks. The shape, body and wall are the same as regular flasks but display the large blue marking spot and designation PYREX VISTA unique to the PYREX VISTA line. Capacity tolerances are twice those specified for Class A volumetric ware. The graduation line is sharp and permanent; large blue block letters make inscriptions easy to read. Heavy duty necks are tooled for No. 2000 polyethylene snap-caps. For replacement snap-caps see No. 7666.
