LUNA-STEM™ – Automated Fluorescence Cell Counter for Stem Cells & SVF

  • Sensitive fluorescence staining
  • Dual fluorescence optics
  • SVF and RBC counting
  • Full reports generated for easy record keeping


The LUNA-STEM™ is a dual fluorescence automated cell counter that measures cell number and viability.

The most advanced fluorescence optics and analysis software enables the LUNA-STEM™ to accurately count nucleated and non-nucleated cells such as stem cells and cells in the stromal vascular fraction (SVF), setting itself apart from other cell counters.

The LUNA-STEM™, integrated with dual fluorescence as well as bright field optics, is a giant leap forward for automated cell counting and viability analysis.

Using two dyes, Acridine Orange (AO) & Propidium Iodide (PI), the LUNA-STEM™ provides sensitive and accurate data for almost all cell types, especially stem cells and SVF cells.

Nucleated & Non-Nucleated Cell Analysis

SVF contains many types of

1) nucleated
2) non-nucleated cells, or
3) non-cell objects.

This composition makes the pure counting of
“adipocytes or adipose-derived stem cells” very difficult.

LUNA-STEM™ uses 2 fluorescent dyes, acridine orange (AO) and propidium iodide (PI), to measure cell viability in a variety of cell type.

With the LUNA-STEM™, all nucleated and non-nucleated cells are counted and analyzed. For example, the LUNA-STEM™ can detect and analyze the various SVF nucleated cells (adipocytes, blood cells, and others) and non-nucleated cells (RBCs, microvascular elements, and others), which is currently an impossibility for other cell counters.


  • Powerful on-board analysis
    Once the LUNA-STEM™ has counted your cells, the built-in software immediately generates cell viability data. Green and red circles indicate live and dead cells, respectively.
  • Cell size gating
    Counted cells can be gated based on cell size. Using the histogram that displays live and dead cell population, you can easily exclude or include specific sizes by simply dragging the ends of the histogram.
  • Image overlay
    Three images captured from each channel (bright field, green, red) can be merged directly on the screen. The individual brightness of each color can be adjusted. All images can be saved onto an external USB drive.
  • Data report
    The analyzed data can be saved as a PDF report or CSV file. Counting results, cell images, and histograms are combined into a single PDF file and saved to an external USB drive.


COST EFFICIENT: The new LUNA™ Reusable Slide has been designed to work with the LUNA™ family of cell counters for cost-efficient and accurate cell counting. The LUNA™ Reusable Slide has the affordability of manual cell counting without the associated subjectivity and time.

: LUNA™ Cell Counting Slides offer the ultimate counting experience. With no mess or cleanup, these disposable precision slides maintain the highest standard of cell counting accuracy.


The LUNA-STEM™ provides a compact mobile printer for further record keeping purposes. Thermal or label paper can be used.

The mobile printer is ready to use with a simple USB connection.
