Clinical serology and blood bank laboratories use the standard transfer pipet as the primary manual reagent dispensing tool for tube serology testing — one pipet per reagent per patient in the daily antibody screen and type-and-screen workflow. Microbiology laboratories use them for broth-to-tube inoculation, colony suspension, and organism transfer in the laminar flow hood. Histology staining labs dispense hematoxylin, eosin, and counterstaining solutions from staining trays using transfer pipets, where the single-use sterile format eliminates cross-staining-bath contamination. At 500\/Bag, the standard transfer pipet is the highest-volume SKU in the series — sized for daily high-throughput serology and serology reference laboratories.\u003c\/p\u003e \u003ch2\u003eU.S. Manufacturing, Quality \u0026amp; Institutional Procurement\u003c\/h2\u003e \u003cp\u003eCaplugs® Evergreen products are manufactured in the United States under ISO 9001 quality management from FDA-compliant, food-contact-grade resins.
