Filter Tips by Qiagen · SKU 990352 Overview Qiagen 1000 µl wide-bore filter tips are disposable pipette tips designed for liquid handling tasks that require increased orifice diameter to minimise shear stress and facilitate aspiration of viscous or particulate-containing samples. The integrated aerosol barrier helps reduce the risk of contamination entering the pipette shaft during pipetting. Manufactured from polypropylene, the tips are designed for compatibility with standard 1000 µl air-displacement pipettes. The wide-bore geometry supports handling of sensitive biological materials such as genomic DNA or cell suspensions by allowing smoother sample transfer. These tips are suitable for routine laboratory workflows that require controlled aspiration and dispensing while maintaining sample integrity. Highlights Nominal volume capacity of 1000 µl Wide-bore tip opening designed for viscous or shear-sensitive samples Integrated aerosol barrier filter to reduce pipette contamination Polypropylene construction compatible with standard 1000 µl pipettes At-a-glance Product type Wide-bore filter pipette tips Manufacturer Qiagen SKU 990352 Volume capacity 1000 µl Tip style Wide-bore Filter Integrated aerosol barrier Material Polypropylene Compatibility Standard 1000 µl air-displacement pipettes Condition New / Unused Applications Wide-bore filter tips are used in molecular biology and cell biology laboratories for transferring viscous solutions, genomic DNA, or suspensions containing cells or beads. The enlarged orifice reduces shear forces during aspiration and dispensing, supporting gentle sample handling. They are suitable for routine liquid handling tasks where contamination control and sample integrity are important, including nucleic acid workflows, enzymatic reactions, and general laboratory pipetting.
