Sample Prep

Especially useful with precious or difficult samples, magnetic levitation allows users to separate live from dead cells in a fast, simple, and gentle process.

  • Highly efficient separation of only live/viable cells
  • Resistant to clogging and debris
  • Ideally suited to downstream single cell analysis workflows

For detection and screening of circulating tumor cells (CTCs), the Levitas system solves key technical challenges.

  • Marker independent, not epCam specific
  • Not based on size or shape
  • Demonstrated clinical sensitivity


Accurate separation and identification of key cell types, such as activated leukocytes and transfected cells

  • Produce fully viable, unmodified cells
  • Ideal for high-throughput applications
  • Highly selective


Real-time drug response offers a fast, accurate, and simple approach to antibiotic resistance testing.

  • No culture required
  • Fast assay
  • Ability to collect and analyze both affected and unaffected fraction

Stem cells

Effective, fast, and simple separation of differentiated cells from stem cells or iPSCs.

  • Homogeneous cell population regardless of the initial percentage of differentiated cells
  • Fast assay
  • Ability to collect and analyze both differentiated and undifferentiated fractions

Levitas technology can also be used to separate cells based on real-time response to drugs and stressors.

The platform is simple, allowing users to begin with unprocessed whole blood samples or any sample with cells in suspension. In a matter of minutes, the instrument and its software automatically perform levitation; label-free separation; quantification of results based on high-resolution imaging; and analysis by cell number, morphology, and levitation profile. Internally, the system relies on a cell densitometry platform consisting of two magnets mounted on either side of a millimeter-wide capillary channel with mirrors on either side to measure levitation height with a microscope. Both brightfield and fluorescence images are collected.
