  • Patent number: 10052633
    Abstract: An ergonomic vial and tube rack is disclosed for retaining a plurality of vials or tubes containing fluid therein in inclined or vertical upright positions, features of which a mechanism for a variable incline angle; lid/cap receptacles positioned either on a shelf above the vial holders or inside the cover when in an open position; an ice or heat pack compartment or a sealed compartment underneath the vials and/or behind the vials for the limited temperature control; rack to rack pin-to-hole locators for stackability, ease of transportation, and storage; color-coding of vial racks for convenience and work-flow assistance; a transparent front panel or an opening in front of each vial receptacle for additional verification of reagent labels; a rack cover with rows of circular indentations, with or without a disposable lining, for use as shallow reaction dishes for qualitative or quantitative chemical assays, such as pH testing.

  • Patent number: 5773299
    Abstract: A method and reagent for the simultaneous or independent enumeration of reticulocytes in a whole blood sample, without the need to separately incubate the sample and reagent. The reagent contains a reticulocyte staining amount of an unsymmetrical cyanine dye, from about 40 mM to about 60 mM of a buffer selected from the group consisting of imidazole, Tris and Bis-Tris and a dye stabilizing amount of a non-ionic surfactant selected from the group consisting of N, N-bis?3-D-Glucon-amidopropyl! cholamide and a polyoxypropylene-polyoxyethylene block copolymer. The reagent has a pH from about 6.8 to about 7.2 and an osmolarity adjusted to about 280 to about 310 mosm/l with a mono-, or di-, valent alkali salt selected from the group consisting of NaCl, KCl, LiCl, CaCl.sub.2, MgCl.sub.2 and ZnCl.sub.2. The method utilizes the reagent in a no incubation process that also allows for the simultaneous determination of CBC as well as reticulocyte counts and maturity indices.

  • Patent number: 5648225
    Abstract: A multipurpose reagent system for rapid analysis of a whole blood sample allowing the determination of at least five classes of peripheral white blood cells, nucleated red blood cells, and lymphocyte immunophenotyping on automated hematology instrumentation. The multipurpose reagent system lyses red cells rapidly, while it concurrently fixes white cells and preserves surface antigens on lymphocytes. The multipurpose reagent system comprises from about 3 to 7 grams per liter of a non-quaternary ammonium salt, from about 0.04 to about 0.10 percent by volume of an aliphatic aldehyde with one to four carbons, from about 10 mM to about 20 mM of a non-phosphate buffer which is inert to the aliphatic aldehyde, and a sufficient amount of water to give a pH between 5.5 and 7.5 and an osmolality of between about 160 to about 310 mOsm per liter.
