Universal Graduated Sterile Low Retention Filtered Tips

Oxford Lab Products universal fit pipette tips are engineered for laboratories that need reliable, low-retention performance without the premium price tag. Unlike tips that rely on silicon additives or surface coatings to reduce sample adhesion, Oxford integrates hydrophobic properties directly into the medical-grade polypropylene resin. This eliminates the risk of leaching while delivering retention performance that matches or exceeds leading competitors - independent testing shows up to 74% less retention with surfactant-containing solutions and near-zero DNA loss at working concentrations, making these tips well suited for molecular biology, cell culture and analytical chemistry workflows.

Every tip is manufactured using diamond-finished molds in a Class 100,000 clean room environment with fully automated, touch-free processes. The result is an ultra-smooth interior surface and consistent tip-to-tip dimensions that support reproducible pipetting across high-throughput and precision applications alike. All tips are certified free of DNase, RNase, ATP, PCR inhibitors, endotoxins and pyrogens, with gamma-irradiated sterility achieving a SAL of 10⁻⁶. The polymer itself is BPA-free, phthalate-free and USP Class VI certified.

Graduated markings on all tip sizes allow quick visual volume verification, and the thin-wall design maximizes sample recovery from each aspiration. These tips are available in six volumes (10, 50, 100, 300, 1,000, and 1,250 μL) with pack and case quantity options, giving labs the flexibility to scale purchasing to their throughput needs. With broad chemical resistance covering common organic solvents, acids, bases and oxidizers, Oxford tips perform reliably across routine and demanding protocols alike.
