Pipette Tip KJ422-1 (5 ml) (CAT#: STEM-BC-1049-ZJF)

The KJ422-1 pipette tip is a disposable consumable designed for use with mechanical and electronic single-channel and multi-channel pipettors in laboratory liquid handling. It is manufactured from medical-grade polypropylene (PP) using precision injection molding to ensure consistent inner wall geometry, accurate volume delivery, and reliable seal formation. The tip is certified free of DNase, RNase, endotoxins (pyrogens), and human DNA to prevent assay contamination in molecular biology, genomics, and clinical diagnostics workflows. Low-retention variants are treated to minimize liquid adhesion to the inner wall surface, improving pipetting accuracy when handling viscous, protein-rich, or low-volume samples. Filtered tips incorporate a hydrophobic polyethylene aerosol filter that prevents aerosol and liquid from entering the pipettor body, protecting against cross-contamination. Compatible versions are available for major pipettor brands, including Eppendorf, Gilson, Thermo Fisher Scientific, DLAB, Finnpipette, and Hamilton automated platforms. Conductive black tips are available for use with Hamilton liquid-handling workstations and other capacitance-based liquid-level detection systems. The tips are produced in a quality manufacturing standard-compliant cleanroom and are supplied in pre-racked or bulk reload configurations to reduce handling time and contamination risk. Each lot is quality-tested to verify dimensional conformance, seal integrity, and volumetric accuracy, with traceability maintained through quality manufacturing standard documentation. The product is suitable for a broad range of applications including PCR setup, ELISA, cell-based assays, sample reformatting, and automated dispensing.
