WOLF G2 Cell Sorter

At < 2 psi, the WOLF G2 are gentler than any conventional cell sorters, enabling healthier cells post-sort, especially for engineered lines, primary cells, and stem cells.

All laser configurations afford < 250 MESF sensitivity, along with forward and back scatter, providing as low as 1 μm resolution.

At 2 cubic feet, NanoCellect’s benchmark for access and performance allows every lab for the flexibility to do analysis and sorting into tubes or 96- and 384-well plates.

Intuitive software, fixed optics, no fluidics cart and less than one minute clean-up time.

Disposable, aerosol-free microfluidic cartridge allows for sterile sorting that protects the sample from the environment and scientist from the sample.

With two lasers and up to nine fluorescent channels, the WOLF G2 aligns with a broad set of research applications and experiments. Three different laser configurations allows options specific to your needs.

Healthy Cells. Broad Capabilities. Better Science.

The WOLF Cell Sorter, born out of a team’s determination to tackle the challenges of biological research, has evolved alongside scientific progress with introduction of the WOLF G2 Cell Sorter pushing the boundaries of gentle benchtop microfluidic cell sorting. Equipped with two lasers and up to nine colors, it empowers researchers with expanded capabilities while maintaining user-friendly workflows for bulk sorting or precise single-cell dispensing. Leveraging the N1 Single-Cell Dispenser, the WOLF G2 Cell Sorter facilitates single-cell sorting into 96- or 384-well plates. This remarkable flexibility, combined with the enhanced functionality of the second laser, makes it a go-to solution for diverse fields like single-cell genomics, cell line engineering, gene editing, antibody discovery, immunology, infectious disease, plant biology, basic research, and more. Experience the future of advanced cell manipulation with the WOLF G2 Cell Sorter and unleash the potential of your research.

Cartridge based fluidics

NanoCellect’s innovative approach to cell sorting encompasses both bulk and single-cell sorting through its unique and exclusive microfluidic cartridges. The microfluidic sorting cartridges operate at less than 2 psi to enable gentle sorting that preserves cellular viability and RNA integrity, as well as eliminate aerosol generation. With a 100% disposable fluidic pathway, these cartridges are particularly advantageous for laboratories handling numerous samples, mitigating concerns related to cross-contamination and biohazard cleanup. The combination of zero aerosol generation and the sterile microfluidic sorting cartridges provides an end-to-end fluidics path, that delivers one of the safest sorting experiences available. Additionally, these cartridges offer remarkable flexibility, allowing users to sort cells using their preferred buffers and media while consuming only approximately 50 mL of sheath fluid per day. Experience the power of single-cell dispensing, cell line engineering, and single-cell isolation with NanoCellect’s cutting-edge microfluidic sorting cartridges.

The WOLF G2 uses laser-based flow cytometry technology for detecting and sorting a variety of cell types, including mammalian, plant, fungal, and bacterial cells. The WOLF G2 cell sorter utilizes typical Forward- (FSC) and Back- (BSC) scatter detectors—as well as 3 different laser configurations to broaden its capabilities. In combination with the N1 single cell dispenser, scientists can complete both bulk and single-cell sorting. A simple cytometer, with powerful impact, allows researchers to sort their own cells on their own bench.

WOLF G2 Cell Sorter


  • WOLFViewer software walks users though a simple workflow by offering step-by-step wizards to make the sorting process as straightforward as possible. As a result, the software uses an intuitive workflow allowing users to quickly complete setup.
  • After setup, WOLFViewer makes analyzing and creating gates simple—while still providing full-featured flow cytometry tools.
  • Key tools like automatic compensation and index sorting, are streamlined and included.
  • When sorting is complete, shutdown and cleanup is literally less than a minute, allowing users to rapidly conclude their work.
  • Researchers have the option of 2-way sorts for bulk sorting and 1-way sorts for single-cell dispensing through the WOLFViewer software.

The WOLF is a technology that enables small companies to do things they could not do before.” “The microfluidics capability is something that I have been excited about. The nature of how the WOLF works is being extremely attractive to us. Some of the experiments we’d like to do in the future could not be done on any other device.

Justin Chartron, Ph.D. Protabit LLC

Neurons are extremely delicate so the selection step should be the least disturbing of all if we want to have reliable results. When we tried the WOLF, we were extremely surprised that our cells were very healthy and viability was above 90%, sometimes above 95% which is very impressive.

Dorota Skowronska-Krawczyk, M.Sc.,Ph.D. University of California Irvine

A great machine that has helped us take our cell-engineering pipeline to the next level!

Ronan O'Connell Rice University

The NanoCellect team and technical specialist have been awesome. After two test runs with very involved training/assistance, we have been very pleased with the results. The equipment is intuitive and the sorts have been very clean.

B. Davenport, Ph.D. University of Colorado
