Filter pipette tips use a membrane which functions as a barrier between the pipetting head and the liquid it is aspirating and dispensing. These tips undergo a robust manufacturing process and multiple quality inspections to ensure proper tip quality and filter placement minimizing cross-contamination and reducing aerosol intake into the workstation. This makes them ideal for qPCR, NGS, and other sensitive applications.
Sterile
Sterile pipette tips are made from medical grade, 100% virgin polypropylene and have been sterilized using irradiation to the current regulatory maximum of 10-6 SAL. This is equivalent to the sterility assurance level (SAL) required by the medical device industry and ensures a product free from bioburden, human DNA, pyrogens, DNase, and RNase. These tips are optimized for cell culture applications.
Conductive
Conductive pipette tips are manufactured with a small amount of graphite along with the polypropylene to enable an electric current in the tips. The graphite is inspected to ensure a proper conductivity of 1-25 kOhms before the tips are manufactured. These conductive tips allow the Fontus and JANUS® workstations to detect the surface of liquids and pipette from a defined depth relative to the surface of the liquid.
Wide bore
Wide bore pipette tips have a distinct wide shape at the end of the pipette tip. This enables the Fontus and JANUS workstations to aspirate and dispense liquid in a gentler manner and is designed for viscous materials like the buffy coat of fractionated blood. These tips are polished with precision tools to reduce sheer minimizing liquid retention and reducing molecular distortion in sample aspiration. These tips are ideal for working with cellular matrices, genomic DNA, and other viscous sample types.
