ABSTRACT:
A chromatography cartridge. In some embodiments, the chromatography cartridge can include a tubular housing defining a longitudinal axis and including a relatively non-laser-writable first portion, and a relatively laser-writable second portion. The relatively laser-writable second portion can be positioned substantially parallel to the longitudinal axis and can define at least a portion of an outer surface of the tubular housing to allow data to be printed on the outer surface of the tubular housing with a laser.
