Safety Information
For the best results, users of the LUNA-FL™ Automated Fluorescence Cell Counter (or, hereinafter
“LUNA-FL™”) must follow the instructions below in addition to the general precautions for using
electrical instruments.
1. Users must be careful to avoid electric shock while operating the instrument. Do not touch it or its
components with wet hands. Do not place it in a humid environment such as an incubator. For more
info, refer to Section Environmental Conditions.
2. Trypan Blue Stain, Acridine Orange Stain, Propidium Iodide Stain, and other reagents are known
as hazardous materials. While handling the solution, always wear gloves to avoid exposure.
3. Before use, make sure that the input voltage is compatible with the instrument’s power supply
voltage.
4. For optimal operations, place the instrument on a flat bench and avoid any vibration.
5. Turn on the instrument only after connecting both ends of its power cord to the wall outlet as well
as the instrument. Always turn off the instrument before disconnecting the power cord and/or
moving the instrument.
6. Ensure that the power cord is firmly plugged into the power inlet, the wall outlet and AC adapter.
7. When the instrument is operating for a long time, its temperature can become too high. Please be
careful that the instrument’s temperature does not become too high during long and continuous
operation times. When operating, leave enough space around the instrument so there is enough
room for air circulation and cooling.
8. Do not disassemble the instrument in any event. If the instrument is out of order or dropped or
broken, please contact a service person. Disassembling the instrument invalidates its warranty.
9. Use only authorized components (adaptor, power cord, and USB drive).
10. If the instrument emits smoke, disconnect the power cord immediately from the wall outlet and
contact a service person.
11. Used counting slides must be disposed as biohazard waste.
12. The LUNA-FL™ Automated Cell Counter is an electrical laboratory instrument for scientific research
use only. It is not a medical, therapeutic, or in vitro diagnostics device.

General Guidelines for Using the LUNA-FL™ Automated Fluorescence
Cell Counter
In order to achieve the best results with the LUNA-FL™ Automated Fluorescence Cell Counter, users
must follow the instructions below carefully.
1. The instrument must be operated in compliance with the environmental conditions described on
page 7. In particular, the temperature and humidity conditions are important.
2. Samples must be handled in an appropriate way, depending on user’s requirements.
3. Hold the slides by the edges to avoid touching the optical surface. Make sure that no damage or
contamination occurs on the optical surfaces of the slide.
4. After mixing the cell sample with the supplied reagents, perform cell counting within 1-3 minutes
for accurate cell viability measurements. Optimally, count your sample at least twice (duplicate
readings) to obtain better results.
5. Since the LUNA-FL™ is calibrated before shipping, users generally do not need to re-calibrate
before use. However, if re-calibration is needed, for example due to long-term use, please refer to
Section 9.3 Calibrating the Counter.
6. Do not touch Trypan Blue Stain and other reagents with bare hands, as they are hazardous
chemicals. After using slides, dispose of them as hazardous waste. Do not reuse the slides.

Chapter 1 –Introduction
1.1 Product Overview
The LUNA-FL™ Automated Fluorescence Cell Counter is a small, fast, and affordable image-based
cell counting device, containing bright field and dual fluorescence optics, that automatically counts
various kinds of cells for research use.
The LUNA-FL™ helps measure the number as well as the viability of cells (live, dead, total cells) with
sophisticated optical components and advanced image analysis algorithms. Due to the innovations
introduced by Logos Biosystems, the LUNA-FL™ provides a state of the art cell counting device and
eliminates the tedium and subjectivity of manual cell counting.
The LUNA-FL™ can be used in a very simple procedure. For example, in order to accomplish dual
fluorescence counting, first, mix 18 µl of the cell sample with 2 µl Acridine Orange/Propidium Iodide
Stain (in case that there is not enough cell sample, 9 µl of the cell sample with 1 µl of the PhotonSlide™
or LUNA™ Reusable Slide can be used to load the total 10 µl in the counting chamber). Second, load
10-12 µl of the mixed cell suspension into a PhotonSlide™ or LUNA™ Reusable Slide. Third, insert the
slide into the slide port of the instrument and adjust the focus knob to get an appropriate cell image.
Last, press the “Count” button and the results of cell count and viability will be displayed on the screen.
The counting image can be downloaded onto a USB drive in a TIF format for future analysis.
<Acridine Orange/Propidium Iodide Stained Cell Image>
Assay principle: AO stains all cells, and PI stains dead cells only. If AO and PI exist together, AO
fluorescence is mostly quenched by PI. Therefore, AO fluorescence (green) is found in live cells only,
and PI fluorescence (red) is found in dead cells only. Cell viability analysis using Acridine
Orange/Propidium Iodide double staining is a proven and accepted method.

The LUNA-FL™ Automated Fluorescence Cell Counter provides the data below.
Number of live and dead cells and their concentrations
Number of total cells and their concentrations
Viability percentage (% live cells to total cells)
Cell images (showing live cells as green circles and dead cells as red circles)
Histogram of cell size distribution and size gating
Number & percentage of the GFP-transfected cells
The PhotonSlide™ is disposable and specifically designed for the LUNA-FL™. Each counting slide has
two chambers, labeled A and B, one slide can be used for the same sample reading in duplicate or it
can be used for two different samples.
Key features of the LUNA-FL™ are as follows:
Key features
Description
Bright field & dual fluorescence
optics
The LUNA-FL™ integrates bright field, as well as dual
fluorescence optical components to provide advanced cell
counting functionalities. The cell image acquired from each
channel (bright, green, and red) can be merged directly on the
screen. The brightness of each color can be adjusted
independently for accurate monitoring.
Small footprint
Due to its minimal size (22 cm x 21 x 9 cm) & weight (1.8 kg), it
can be used on a clean bench or stored in a biosafety cabinet
for convenience.
Accuracy & precision
Due to its sophisticated optical components and counting
algorithm, LUNA-FL™ cell counter provides reproducible
results every time.
Easy-to-operate user interface
The intuitive user interface based on a touch screen enables
simple and easy operation.
Shortest time-to-results
Results for most cell lines are available within 7-30 seconds of
pressing the ‘Count’ button.
Innovative counting slide
LUNA-FL™ cell counter adopts an innovative counting slide
made with “T-bond” technology without using hazardous
organic solvents.
Cell concentration & viability range
Measurements can be made for cells at concentrations within
the 1 x 104to 1 x 107(preferably 5 x 104to 1 x 107) cells/mL
