S-1320 Chromatographic Apparatus Nuetral Oil

This designed flask increases the efficiency and standardization of neutral oil determination. Permits automatic transfer of weighed crude oil samples on to alumina columns, converts column operation to a semiautomatic level, thus reducing cost of operation and allows the chromatographic procedure to be performed in laboratories which are not air conditioned.
