With four counting modes, the LUNA-FL™ is our powerhouse. Equipped with brightfield and dual fluorescence optics that allows the sensitive detection of most cell types excluding bacteria. The LUNA-FL™ can distinguish primary cells such as PBMCs, splenocytes, neutrophils, and stem cells from undesirable debris for accurate cell count and viability results. Brightfield cell counting, fluorescence cell counting, yeast cell counting, and GFP transfection assays are all in the LUNA-FL™ wheelhouse. This versatile little counter sits comfortably in a cell culture hood or on your benchtop to fit seamlessly into your workflow.

  • Gelina Sani

    Children's National Medical Center

    The LUNA-FL is one of my favorite machines in our lab. It lets me acquire cell counts so quickly so I can go on with my bench work. Not only are we able to count but we can look at other statistics like viability and average cell size with just the push of a button. The best part about this counter is the accuracy. I am able to reliably count every cell line that I put in, and am able to do it again the next day. I'm so glad we have this system in our lab because counting with trypan blue would take much longer! Overall, I would recommend this product to another lab that is doing a lot of work with cell lines in order to get a quick and accurate count.

  • Mikayla Lopes

    Roger Williams Medical Center

    The LUNA-FL is an extremely easy device to use and very user friendly. With many different modes available, it is certainly a useful tool in the lab. Our service rep is extremely responsive and helpful to our needs and questions. Highly recommend!

  • Regina Wulff, MS

    Weill Cornell Medicine / New York-Presbyterian Hospital

    The LUNA-FL consistently produces fast and reliable results. The counts and viabilities provided by this instrument are consistent with values provided by flow cytometry. This product is remarkably easy to operate, care for, and maintain. In comparison to similar products on the market, the LUNA-FL is exceptional for the low cost.

  • Danh Tran

    Medical University of South Carolina

    Our lab was interested in an automated cell counter because we needed something reproducible enough to compare between groups and to use cell count as a quick approach for normalization. … The LUNA-FL fit our needs the most, and the price was close to our budget. So far, it has been used for many purposes in our lab, including the original assay that we were trying to develop and other applications including quick live/dead information, GFP expression, etc.

  • Woong Sun, PhD

    Korea University Medical School

    I would recommend it simply because it can count a heterogeneous sample obtained from mouse brain. I was surprised by the accuracy of this tiny instrument.

  • May Malicdan, MD PhD


    It's very convenient to use and very accurate. Especially in the transfection procedures, it's very helpful. Overall, we're very pleased.

  • Joanna Ireland, PhD


    It works really well. It's easy. It's accurate and fast. I especially like the dual fluorescence and being able to focus on the green and red cells.

    • LUNA-FL™ Dual Fluorescence Cell Counter HL-60 50viability
    • HL-60 (50% viability)

      Experimental condition

      HL-60 cells were artificially killed by heating and mixed with healty cells (50:50). Mixed cells were stained with acridine orange-propidium idodide mixture and then counted with the LUNA-FL fluorescence cell counter.

    • HL-60 (high density)

      Experimental condition

      A high density culture of HL-60 cells was counted with the LUNA-FL to verifiy the performance of the instrument. Cells were stained with acridine orange-propidium idodide mixture and then counted. Green and red circle represents viable and dead nucleated cells automatically classified by LUNA-FL.

    • Human peripheral blood

      Human whole blood was collected from a finger tip and diluted in PBS at 1:100. After staining with the AO/PI dyes, white blood cells (WBCs) were counted with the LUNA-FL fluorescence cell counter. Bright field and its corresponding fluorescence image are shown in the left and middle panel, respectively. Area enclosed by the white rectangle is shown in the right panel at high magnification. Note that cells containing nucleic acids (ie., WBCs) were counted and tagged with the green circle. A huge number of red blood cells (RBCs) and platelets seen in the bright field image were not counted by LUNA-FL. No dead WBC was observed in this field of view.

    • Jurkat

      Experimental condition

      Jurkat T cells were stained with acridine orange-propidium idodide mixture and then counted with the LUNA-FL fluorescence cell counter.
