  • Publication number: 20210008566
    Abstract: Systems and methods for handling a variety of sample and preparatory fluids in a rack specifically configured for compatibility with predetermined liquid handlers such as automated pipettors or multi-channel manual pipettors and set up for magnetic based sample preparation. The rack can hold all of the necessary sample and reagent vials, and present them to the pipettor in some embodiments in a way that allows for parallel operation. The rack includes slidable magnets that in some embodiments are actuatable directly by the pipettor, eliminating a layer of complexity. Combined with a suitable pipettor the magnet enabled rack supports a multistep magnetic based sample preparation capability in a high throughput manner at one station that enhances sample purity throughout magnetic separation processes.

  • Publication number: 20190283022
    Abstract: A highly parallel microfluidic blood separation device for isolation of variety of analytes for large-scale clinical trials. The device can be utilized for isolation of number of different target analytes, which may be the starting materials for variety of diagnostic methods including NGS, PCR, FISH, IHC, and others. Separation is achieved via magnetic sheath flow principals and is highly parallel. The separation device achieves effective magnetic separation, functions during sample flow in a vertical geometry and may fasten to standard multi-well plates for highly multiplexed sample recovery. Operating in vertical orientation allows multiplexing, more cards/slot/bay on instrument, allows effective use of real estate on instruments and bench tops.
