These high-quality pipette tips are compatible with the JANUS® G3 VariSpan™ pipetting module and can be used for a variety of automated liquid handling applications. Each individual tip has a small amount of graphite added, to enable the detection of the surface of liquids, a membrane filter, to create a barrier between the VariSpan pipetting head and the liquid, and a distinct wide shape at the end of the pipette tip, to aspirate and dispense more viscous materials in a gentle manner. Volume range 100 to 900 µL.
