These borosilicate glass indicator adsorption columns are used to determine saturates, nonaromatic olefins and aromatics in petroleum fractions that distill below 315°C as specified in ASTM Method D-1319. The standard flourescent indicator column is drawn to a fine point for retaining silica gel. The precision engineered flourescent indicator column has a removable capillary tip joined to the analyzer section by a 12/2 spherical joint. Columns have a 28/12 socket joint at the top.
