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.
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.
