A prefabricated micro-quantity reagent dosage unit for an analytical procedure, is provided involving reaction of a chemical reagent with a reaction mixture to be analyzed. The unit comprises a composite structure which incorporates the chemical reagent and includes carrier means for carrying the chemical reagent and magnetizable material to facilitate handling of the carrier means and for effecting movement of the latter, under action of a magnetic field acting on the magnetizable material, when the carrier means is subjected to the reaction mixture. The carrier means is provided with precise micro-quantities of reagent preparatory to a single analysis and by virtue of the magnetizable material the composite structure may readily be handled for storage under conditions favorable for the durability of the reagent, simultaneously enabling transfer of the composite structure to the reaction mixture without risk of contamination of the latter.
A prefabricated micro-quantity reagent dosage unit for use in the course of an analytical procedure involving reaction of a chemical reagent with a reaction mixture to be analyzed, said unit comprising a chemical reagent of predetermined volume, a tube open at both its ends for carrying therewithin said chemical reagent of predetermined volume, sealing means cooperating with said tube for sealingly containing said reagent therein during storage, and a magnetizable material embedded in the wall of said tube to facilitate handling of said tube and for effecting movement of the tube, and thus the reagent carried thereby, when subjected to said reaction mixture, said tube, said reagent, said sealing means and said magnetizable material comprising a composite structure adapted for storage, transfer and use in a single analytical procedure under action of magnetic forces adapted to be applied to said magnetizable material.
