ABSTRACT:
To make an inexpensive chromatographic column and perform chromatography with it, column walls and a column end with an inlet port are molded integrally from plastic and a snap-on end is molded integrally with an outlet port from plastic. A filter is placed in one end of the column and the column is filled with packing material up to the second end. A filter is placed on top of the packing and a snap-on end with a molded outlet port is snapped onto the body with linear motion until an interference fit is formed. As the body and snap-on end are moved together cantilever members formed integrally with the snap on end are bent outwardly by detent members until the detent members are captured by an opening in the cantilever members.
