“The team demonstrated CVs of less than 1% over a wide pipetting range, from ~15µL to ~400µL.”
Right: A plot showing CV against aspirated volume, from ~15uL to ~400uL. The experimental set-up used a VCM without a pipette tip, so that fluid-tip interaction inconsistencies could be mitigated. We used a high-sensitivity liquid flow sensor and integrated the output to calculate dosed volume. Details of this setup are presented in Application Note AN049.
