A reagent storage and delivery apparatus comprises a reagent cartridge having a plurality of fluidic chambers and includes a flange means for receiving a label to define a code indicating information concerning the contents of the cartridge. Preferably, a binary code is defined through use of windows formed in an extending portion of the cartridge which cooperate with a formed portion of the label applied to the cartridge. The binary code is optically read and translated to a digital information signal for instructional use with an analytical instrument.

A reagent storage and delivery apparatus for an analytical instrument performing chemical analysis, comprising: a reagent cartridge comprising a plurality of chambers for containing fluidic reagent, each chamber having an entry port and resealable seal means for receiving a probe to withdraw reagent

A reagent storage and delivery apparatus for an analytical instrument performing chemical analysis, comprising: a reagent cartridge comprising a plurality of chambers for containing fluidic reagent, each chamber having an entry port and resealable seal means for receiving a probe to withdraw reagent from the cartridge, and further comprising a flange member extending outwardly from said cartridge and including a plurality of openings formed therethrough to define windows through which an optical signal may be transmitted; label means for cooperating with said flange member, said label means comprising an end portion selectively formed to cover selective ones of the windows of said flange member to determine a grouping of open and closed windows which may be used to define a binary code; receiving means for receiving said reagent cartridge for operation with an analytical instrument, said receiving means defining a receiving space closely fitting the shape of said cartridge to precisely guide the cartridge for insertion into said receiving means to permit probes held by said receiving means to transfix said seal means of said cartridge to enter said entry ports for withdrawal of reagent from said cartridge; and means for reading said code defined by said cartridge and said label means, to provide information contained by said code to the analytical instrument for facilitating chemical analysis.
