Compound library management uses PS deep well plates for DMSO compound stock storage and daughter plate generation where the DMSO concentration is low enough for PS compatibility. High-throughput screening laboratories use PS deep well plates for aqueous sample pooling, buffer transfer, and compound dilution steps where organic solvent contact is minimal. For strong organic solvent workflows (protein precipitation with acetonitrile, LLE with ethyl acetate), the PPC alternatives (222-8649-080 for 0.5 mL non-sterile, 222-8664-08N for 1.0 mL sterile) provide better material compatibility.\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.
