A cell sorter with brand new technology offering excellent operability and user-friendly maintenance. Unlike a conventional cell sorter, all fluids remain on a sterile and disposable microfluidic chip. The microfluidic cell sorter not only resolves the inherent issues of the conventional sorters, but also enables analysis/sorting of cells suspended in culture medium. Cells are sorted by On-chip's unique "flow shift" method in microchannels, avoiding shear stresses, pressure changes, collisions, and strong electrostatic field which might damage or alter the cells. Because our sterilized microfluidic chips are disposable, cross-contamination between samples does not occur. It is compact enough that it can fit inside a biosafety cabinet, with no generation of aerosols. This is an ideal solution for safe handling of biohazardous materials, where safety is paramount. Small sample volumes (~20 μL) can be analyzed without almost no dead volume. On-chip Sort is the most suitable instrument for the analysis and sorting of precious samples. Maintenance of On-chip Sort is easy. Fluids does not get in contact with the instrument, so no cleanup is required. On-chip Sort is easy to operate and does not require hours of training. Run the sort with your preferred buffer: culture media, sea water and even oil.
