CHROMATOGRAPHY COLUMNS

These columns are for use in general chromatographic work for extraction of components, with special applications in isoenzyme and protein studies, hemoglobin fractionation, and desalting. Chromatography columns are precision-molded in 5" and 7" sizes from premium grade, chemically inert plastics.

Polystyrene columns are glass-clear and appropriate for use with mild acidic (exept oxidizing acids) and alkali solutions. Polypropylene columns are contact-transparent, more-chemically resistant, and appropriate for use with organic solvents and stronger acids (except oxicizing acids) and alkalis.

Chromatography columns include resovoir & end caps, and pylyethylene filter matrix suports in one of three porosities.

EXTRACTION COLUMNS

These columns are for use in drug extractions, HPLC sample preparation, general chromatography applications, and other research procedures, and may also be use "piggybacked."

Columns measure 3 3/8" long and include a medium polyethylene filter matrix support. Large reservoirs and cartridge portions with straight sidewalls accommodate solid-phase packing material such as silica and alumina. Columns are available in either natural polypropylene or light-shielding amber color.

Evergreen has added two mini-columns molded in polypropylene in the study of molecular biology.

The first one is 1.9 inches overall in height. It has a capacity of 0.5 ml. This column features a HDPE filter of medium porosity (45-90 micron).

The second column is 1.5 inches overall in height. It has a capacity of 5 ml. This column features a HDPE filter of medium porosity (45-90 micron).
