These four brands share compatible cone dimensions at this volume range — one Caplugs Evergreen SKU replaces OEM tips across all four brands, simplifying procurement and reducing the number of separate tip SKUs a laboratory must manage. The yellow color matches the standard OEM color convention for this volume range, enabling smooth transition from OEM supply without retraining laboratory staff on new color identification. At below-OEM per-tip pricing in 1000\/Bag format, these tips provide meaningful per-tip savings for high-volume labs running hundreds of pipetting operations per day in this volume range.\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.
