Logos LUNA-II™ Automated Cell Counter (without printer)


  • Fully automated cell counting and cell viability analysis
  • Autofocus technology for fast and reliable cell counting
  • Various histograms and cell-size gating
  • Unmatched counting accuracy and speed
  • Built-in computer and printerThe most affordable running cost currently on the market

The LUNA-II™ automated cell counter has integrated a novel focusing mechanism based on liquid lens technology.
The liquid lens does not use any mechanical moving parts to change the Z stage. Instead, the Z position of the sample is rapidly
obtained by the application of a small voltage to the liquid lens. The elimination of moving parts removes noise and significantly
reduces the need for servicing. Even after multi-million cycles of focusing, the liquid lens does not require repair or service. 
In combination with this novel focusing mechanism, the LUNA-II™ has integrated a new autofocusing algorithm optimized for
cell counting.


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.

CONVENIENT: 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-II™ automated cell counting algorithm has been recognized to have the best-in-class cell counting accuracy. 
The LUNA™ software has exceptional accuracy in cell de-clustering and can successfully count clumpy cells. The LUNA-II™ automated 
cell counter has inherited this well-known performance aspect of the LUNA™ software. Clumpy cells are de-clustered quickly 
and automatically, then counted as individual cells.


Although the LUNA-II™ can detect and count unstained cells, viability information can only be obtained from stained cell solutions. The traditional trypan blue can be used with the LUNA-II™, as well as the safer Erythrosin B. Both dyes produce consistently accurate cell count and viability data with the LUNA-II™. 

Read the following article for more information on Erythrosin B-stained cell viability data: “Application of a non-hazardous vital dye for cell counting with automated cell counters”.

Options for staining methods

The LUNA-II™ automated cell counter can count samples with or without trypan blue dye. The selection of trypan blue presence
or absence can easily be chosen in the settings menu.

Cell size histogram and cell size based gating

After counting, cells can be gated based on their size information provided by the LUNA-II™. The specific size of cell populations 
Can easily be included or excluded on histograms.

Cell cluster map

Counted cells can be sorted with cell cluster map, into single cells, doublets, or triplets.
The cell cluster map can be used to monitor changes in culture conditions or cell isolation/preparation protocols.

Review and Re-analysis option

The LUNA-II™ automated cell counter provides a powerful review option.
A separate PC unnecessary. Users can open cell images directly on the LUNA-II™ automated cell counter
to check previous results.

Various file save options

The LUNA-II™ can store up to 1,000 counts onboard. After counting, the result is automatically saved in the memory, and previous count results can be exported via USB as a .CSV file for further analysis. The results and image data can be saved in three different file formats such as TIF, annotated TIF, or a PDF report file. The PDF report file contains all the data generated during/after the cell counting, i.e., the protocol used, cell counting results, date, raw/analyzed cell image(s), and histograms are included in the PDF report file.
