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.



Capture, analysis and measurement of 3 fluorescent images in just 30 seconds and in bright field mode you will get one image and all measurement data in just 10 seconds.



High resolution images are captured and analyzed to detect GFP-positive and -negative cells.the capture and analysis process takes just a few seconds

Dual Fluorescence


The Luna-FL automated cell counter from Logos Biosystems is a quantum leap for automated cell counting and cell viability analysis.

The Luna-FLgives you sensitive and accurate live/dead cell counting results without limitations of cell types.

Unlike immortalized cell lines primary cells such as PBMCs splenocytes, neutrophils, and stem cells have been difficult to count with conventional cell counters such as coulter counter or image-based automated cell counters that utilize bright field optics.

Primary cells are often contaminated with undesirable debris, which can be confused with cells with conventional cell counters.

The Luna-FL is integrated with dual fluorescence microscope optics to overcome this problem.

Live/dead cells are stained with green/red fluorescence dye, and labelled cell images are analysed with accurate image analysis software


Data report

1000 measurement data directly stored

The analysed data can be easily saved as a PDF or CSV file. Cell counting results, cell image data, and various type of histograms are integrated into a single PDF file and transferred via USB drive. Data from previous cell counts (up to 1000 counts) are archived in the LUNA-FL




Perfect for labs on a budget, our LUNA™ family of automated cell counters work with the LUNA™ Reusable Slide. The LUNA™ Reusable Slide delivers the affordability of manual cell counting without the associated time, subjectivity, and user-to-user variability. Our disposable slides offer the ultimate counting experience. With no mess or cleanup, these precision slides are convenient and maintain the highest standard of cell counting accuracy.

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.

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

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.

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.

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!

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.
