Kimble® KIMAX® Class A Square Volumetric Flasks with [ST] Glass Pennyhead Stopper, 28040

This KIMAX® volumetric flask has a square cross-section and a width less than the widest diameter of a usual round flask. Especially designed to take up less area and pack more closely to conserve storage space, they require 25-35% less area than conventional flasks. Due to the added glass weight and the square section, these flasks also provide greater stability. Calibrated 'To Contain', there is a blasted on graduation ring and marking spot. A standard taper ground glass stopper is supplied with the flask. Designed from ASTM Specification E288, Class A unserialized requirements. Replacement stopper is 41900R.
