"The LUNA-FL is very easy to use and gives reproducible results for cell counting, especially for the "difficult" single cell suspensions, prepared from fresh tumor tissue. Here, the use of the LUNA-FL is crucial for counting as it can distinguish very well between live cells / dead cells and cell debris. For all our applications (e.g. organoid seeding), an accurate cell count is essential. Also, I like the tagging option to analyze the cell count as well as the possibility to save the data on a USB stick for later."

"Fast and easy to use"

"I have been using this LUNA counter for one year, it’s simple and easy. it comes with the reagents. The accuracy of the cell count is very important with the viability of cells. It is easy for multiplex samples."

"Fast and user friendly"

"This cell counter is very easy to use. It gives fast and accurate counting results. Has both brightfield and fluorescence counting which becomes very useful when working with transfections."

"I was able to obtain good agreement between the PI channel of the Luna FL and my own manual haemocytometer counting of nuclei stained with DAPI at a fraction of the time. One caveat would be false 'viability' given from background staining of AO on tissue debris but it could be useful in determining the level of debris from the isolation."

"Excellent device, produces reliable cell counts and saves you a lot of time with a good workflow."

"Other cell counters (trypan blue method) sometimes detected debris, but Luna fL can use AO/PI, so it does not detect debris. The reproducibility of the AO/PI method is high, which is very useful for experiments. It would be great if there was autofocus, as it would be troublesome to manually focus each cell count."

"It's a really nice product that enables you to automatize your cell counting in no time, and that is extremely easy to setup and useful for saving time during your experiments"

"Good value on money, time saving and ease to use. Saves both time and money"
