Safety Information
For best results, users of the LUNA™ Automated Cell Counter 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 and
other components with wet hands. Do not place it in a humid environment such as an incubator.
For operating environment, see page 7.
2. Trypan Blue Stain is a known hazardous material. 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 operation, 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 malfunctioning or broken,
please contact your local distributor or Logos Biosystems. 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. Do not reuse LUNA™ Cell Counting Slides. Used counting slides must be disposed as biohazard
waste according to the rules and regulations of your local government.

General Guidelines for Using the LUNA™ Automated Cell Counter
In order to achieve the best results with the LUNA™ Automated Cell Counter, users must follow the
instructions below carefully.
1. The instrument must be operated in compliance with the operating environment 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 LUNA™ Cell Counting Slide by the edges to avoid touching its optical surface. Make
sure that no damage or contamination occurs on the optical surfaces of the slide.
4. After mixing the cell sample with Trypan Blue Stain, perform cell counting as soon as possible,
within 3 minutes for accurate cell viability measurement. If needed, count your sample at least 2
times (duplicate readings) and take an average.
5. Since the LUNA™ Automated Cell Counter is calibrated before shipping, users generally do not
need to re-calibrate before use. However, if re-calibration is needed, please refer to Section 5.3
Calibrating the Counter.

Chapter 1 –Introduction
1.1 Product Overview
The LUNA™ Automated Cell Counter is a small, fast, and affordable image-based cell counting
device that automatically counts various kinds of cells for research use.
The LUNA™ Automated Cell Counter helps measure the number, as well as viability of cells (live,
dead, total cells) with sophisticated optical components and advanced image analysis algorithms.
Due to several innovations introduced by Logos Biosystems, LUNA™ provides a state of the art cell
counting device and eliminates the tedium and subjectivity of manual cell counting.
The LUNA™ Automated Cell Counter can be used in a very simple procedure. First, mix 10 µl of the
cell sample with 10 µl of Trypan Blue Stain or Erythrosin B Stain. Second, load the cell suspension
into the LUNA™ Cell Counting 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 TIF format for future analysis.
The LUNA™ Automated Cell Counter provides key data as below:
Number of live and dead cells / mL
Number of total cells / mL
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
Both reusable and disposable slides can be used with the LUNA™. The LUNA™ Reusable Slide is
compatible with the LUNA™ family of automated cell counters for both brightfield and fluorescence
cell counting. Designed for cost-efficient an accurate cell counting, the LUNA™ Reusable Slide
combines the economy of manual cell counting with the speed, accuracy, and convenience of
automated cell counting. The disposable LUNA™ Cell Counting Slides maintain the highest standard
of cell counting accuracy and offer the ultimate counting experience with no mess or cleanup. Each
counting slide has 2 chambers, labeled as Aand B, so that one slide can be used for the same sample
reading in duplicate or for 2 different samples if preferred.

Key features of the LUNA™ Automated Cell Counter are as follows:
Key features
Description
Small footprint
Due to its minimal size (22 x 21 x 8.5 cm) & weight (1.2 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™ Automated Cell Counter provides optimized
and reproducible counting 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 seconds of
pressing the ‘Count’ button.
Innovative counting slide
LUNA™ Automated 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 104–1 x 107cells/mL range and for cells within the 3 -
60 µm diameter range.
Easy-to-use dilution calculator
Dilution concentration can easily be calculated using the built-
in calculator.
Setup & maintenance
Just plug in and it is ready for use, with virtually no maintenance
costs.
Counting image transfer
The counting image can be downloaded onto a USB drive in
TIFF (Tag Image File Format) for later use or review.
Individual protocol saving
Each researcher can set and adjust counting parameters such
as cell size and save the counting protocol for later use.
Automatic reporting
LUNA™ provides a counting report based on the count results
in PDF (Portable Document Format) immediately after
performing a cell count.
Cell information
Cell size, position, and viability information is provided for all
counted cells.
