This chromatograpy apparatus features a flask that increases the efficiency and standardization of neutral oil determination by: permitting automatic transfer of weighed crude oil samples onto alumina columns; and converting column operation to a semi-automatic level, thereby reducing the cost of operation

The complete apparatus consists of: 175mL reservoir with a 4mm PTFE stopcock, [ST] 19/22 inner joint at bottom and #27 stopper joint at top; 20mL flask with [ST] 19/22 joints at top and bottom and a [ST] 7/15 joint on inner tube; base with [ST] 19/22 joint; extension tube with [ST] 7/15 joint; and 19mm I.D. column that is 270mm long from the top of the [ST] 19/22 joint to the tip, with 2mm PTFE stopcock and Porosity C (25-50 micron) fritted disc.
