Robotic Isolation Technology CellSorter

CellSorter develops smart technologies for single cell handling, sorting, and isolation. We design flexible hardware and software for diverse applications(Single cell DNA/RNA sequencing, CTC detection or Protein engineering).

Main Features

  • High throughput single cell sorting directly from the Petri dish
  • One single cell arrives to each PCR tube
  • 10 PCR strips containing 80 tubes can be filled in a cycle
  • Glass cover slip for testing single cell deposition in situ
  • Drop volume less than 1 ul for adherent cells
  • Pick up volume of ~1 nl for suspended cells
  • 15-20 seconds per cell
  • Isolates a subpopulation of live adherent cells expressing fluorescent or luminescent markers
  • Both unlabeled and fluorescent cells are recognized by computer vision
  • Viable cells after sorting
  • Sorts cells labeled by fluorescent molecular probes highlighting specific cellular activities
  • Collects single cells for further cultivation, cloning, RNA or protein preparation
  • Any adherent and non-adherent cell type can be sorted
  • Cell culture needs minimal preparation before sorting
  • Average sorting process takes only a few minutes
  • Multichannel detection using the fluorescent filter setup of the microscope
  • When collecting multiple cells sorting speed is 1 cell/second. Number of cells picked up in a single run: 1-1000

New Piezoelectric Sorting Head for Single Cell Isolation

Pipetting nanoliter scale volumes is challenging due to several technical difficulties including surface tension, adhesion and evaporation effects. We developed a fully automated piezoelectric micropipette with a precision of <1 nanoliter. The piezo micropipette can be fully automated using either fluorescent or transparent illumination on a microscope.

Main applications   single cell isolation, single cell printing, and nanoliter droplet printing.


  • Compact design
  • Excellent liquid handling precision: 0.1 nanoliter
  • Outstanding >90% single cell isolation efficiency
  • Built-in LED illumination for phase contrast imaging
  • No tubes
  • No syringes
  • Control unit with USB connection to the computer ​

Robot Picking Single Cells Controlled By High Speed Valves


  • CellSorter control unit with 2 high speed fluid valves and USB connection to the computer
  • High precision micropipette holding console manufactured from hard aluminum equipped with LED illumination for micropipette focusing and connected to the motorized micromanipulator via a rotatable arm.
  • Special aluminum insert fitting to the microscope stage with a hole and magnetic fixing ring for the 35 mm Petri dish and 80 holes for 10 PCR stripes and a hole for a 32x24 mm2 glass cover slide for testing and high resolution imaging and a hole with a calibration cross­hair
  • Accessories, fittings and tubing for liquid control
  • Compatible with most inverted microscopes
  • Modular structure makes it versatile and helps to fit the device to the specific application
Hardware Requirements
  • Inverted microscope with digital camera, motorized focus, and stage
  • Syringe pump
