  • External material accession systems and methods
    Patent number: 6447661
    Abstract: Methods, apparatus and systems are provided for introducing large numbers of different materials into a microfluidic analytical device rapidly, efficiently and reproducibly. In particular, improved integrated pipettor chip configurations, e.g. sippers or electropipettors, are described which are capable of sampling extremely small amounts of material for which analysis is desired, transporting material into a microfluidic analytical channel network, and performing the desired analysis on the material.

  • Microfluidic matrix localization apparatus and methods
    Publication number: 20020123133
    Abstract: Multiphasic microfluidic apparatus for performing product fluid manipulation and separation in a single continuous unit are provided. Related methods, kits, and compositions are also provided.
    Type: Application

    Applicant: Caliper Technologies Corporation
    Inventors: Tammy Burd Mehta, Anne R. Kopf-Sill
  • PCR compatible nucleic acid sieving medium
    Publication number: 20020012971
    Abstract: Sieving mediums comprising less than about 0.5% polymer, less than about 0.4% polymer, and 0.35% polymer or less are used to perform nucleic acid separations and PCR. The low polymer concentration does not inhibit PCR reactions and is sufficient for performing nucleic acids separations. Microfluidic devices are used to perform nucleic acids separations and PCR reactions in the sieving mediums described.
