These student grade, economy flasks are designed for use in schools that do not require the precision accuracy of Class A flasks. The shape, body and wall are the same as regular flasks but display the large triangular marking spot and designation "Student Flasks" unique to the student line. Capacity tolerances are twice those specified for Class A volumetric ware. The graduation line is sharp and permanent. Snap-caps are supplied with all sizes. (C5581)
