"Quick and accurate cell counts, also useful for counting fungal spores. Incredibly easy to use."

"We purchased this cell counter from BioCat after looking at a few different models online as well as using a week to demo it in our lab. The menu is simple to use and understand. It is easy to update the software version from the website. It is a lot faster than manually counting using a hemocytometer and removes counter variability. Set cell numbers for different cells lines to seed flasks and plates can now be standardized. By purchasing the reusable cell counter slide we can reduce our plastic waste and they are easy to clean with dH2O and dry using a tissue. Being able to switch to the cell screen to see what it counts as a cell (circled in green) and as trash/ debris (circled in red) with the option of increasing the magnification is great to determine if the settings need to be changed for a specific cell line. Automatic cell counters like this are a life saver when needing to seed multiple cell lines for an experiment. The Luna II was the cheapest automatic cell counter that I found, and we haven't regretted it!"

"This product had made cell counting easy rather than counting it under the microscope as we used to do back in the day. After preparing the sample we easily loaded it into the slide chamber. It also tags which cells are live and dead to be easy for the user to count. since it is done through imaging and focus. The user only has to adjust some minor settings for accurate counting like other instruments. Overall, this is a great product."

"We purchased the Luna II to replace our normal cell counting on hemocytometers. Once we optimized the settings for our cell size, shape, and color, the Luna II could give us the same estimated densities in 15 seconds rather than 5 minutes. We are also able to stain our cells with trypan blue for viability counts at the same time. This time-saving machine is also accurate in distinguishing plant cells from junk and giving close approximations to the ones we typically make with glass hemacytometers."

"It is one of the nicest cell counters I have ever use. It is totally worth it."

"The main cell counter that we use before single cell RNAseq. Seems to give consistent results and accurate counts/viabilities. Easy to use and relatively quick."

"The LUNA system is very easy to use. The counting of erythrocytes is fast and very precise. The detection of plasmodium falciparum infected erythrocytes via fluorescence helps us to determine the parasitemia very fast. Counting using LUNA helps us to have more accurate data in less time!"

"This product has made cell counting such an easy process! After preparing the sample, it is loaded into the slide chamber, inserted into the LUNA-FL, and then counted. Learning to use the equipment was quick, and the default setting has worked well in our lab. Assessing the quality of the count is also easily done through imaging and focus. Overall, this is a great product."

"Fast, reproducible and easy to use. Possibility to save protocols and export data. Helpfull to count GFP cells."

"I used the LUNA system to estimate cell density and cell viability. In both cases, once the protocol is well defined and the experimental conditions extremely standardized, the system works very efficiently. It is less efficient in a non laboratory conditions."

"The accuracy of cell count is very important for single-cell genomics experiments, in our hands the LUNA is very reliable and repeatable."

"After enjoying the LUNA Automated Cell Counter's first generation for so many years (red device and quite compact), I decided to add a second one and I recently got the LUNA-II™ Automated Cell Counter 2nd generation (white device and quite bigger in height but low footprint). One advantage, the blades are the same between the 2 generations, well done Logos Biosystems, you are aware of your customers' needs. The software seems faster and always reliable as usual for Korean made. So far no complaints, hopefully the 2nd generation will be as robust as the 1st generation."

"This machine is a very powerful and useful automatic cell counter. As it counts both live and dead cell populations, our time is conveniently conserved."

"Very effective, minimizes errors possed by manual counts."

"Very good, user friendly and fit for our purposes."

"We are very happy with the product and service."

"We purchased he LUNA II for counting purposes. It comes with two reusable slides and a box of 50 disposable ones. The counting is quite accurate and very easy to use. The accuracy was checked with separate haemocytometer counts of each cell line being counted on the LUNA II cell counter and was found to be very close and well within the error rates of the haemocytometer. I am very impressed. Would highly recommend this product to other labs."

"Very easy to use and doesn’t require expensive slides. Easy to take care of in a core facility tissue culture lab."

"LUNA II is a very useful automatic cell counter. Recently, I measured cell viability using LUNA II. Because it counts both live and dead cell populations, on time was conveniently confirmed. Cell size measurement is a very cool feature. I am so satisfied! Will recommend it to everyone!"

"With the LUNA-II Cell Counter you can count your cells in less than a minute. It's not only pretty fast but also very easy to use. Mix your sample with dye, load it into the chamber and you can start counting. Highly recommended."

"The LUNA FX7 Automated Cell Counter has streamlined our workflow and increased the repeatability of our internal experiments. This equipment allows multiple users to achieve verifiable outputs and has increased our capacity at a complicated time when our personnel are limited by their in-person activities. The fluorescence and imaging capabilities of this cell counter has reduced our reliance on older, more specialized equipment. The company was responsive, engaged, and knowledgeable about the right product for our uses."

"One of the most easy to use cell counters I have used so far. The quality of the images stored after counting is as good as seeing through BF microscope. Even clustered cells are well analyzed for cell counting. Higher number of fields and cells taken in to account for precise cell counting."

"Device has been easy to use, and simple for a new user. Autofocus works nicely which is important to us; we need consistant results because different people run cell counting as a first step of single cell analysis. Algorithm seems to work accurately as it differentiates between actual cells and cell debris or other particles. Counting with the 8-chamber slide is quite consistant, you just have to pay attention to even pipetting. Measuring with the 8-chamber slide is super easy and quick compared to Luna-stem that we used to use. Getting 8 counts and also saving all the files with two keystrokes frees you to do something else while the counter is running. Only one thing I would change: It would be good to have some kind of a note on screen when the file has been saved. It often happens that I automatically press "save", then go to do something else and when I come back, don't remember if I actually did press the key. When re-saving, the application does not warn you that the same file is already saved and you end up with double files. Not a big problem though."

"Great products, make cell counting quick and easy, no more staring under microscopes and clicking the cell counter for hours."

"Very good product, easy to use and reliable!"

"It is excellent because of the following: 1-Its ease of use. 2- Reproducibility of data. 3- Take less time to process than others. 4- Reliable. 5- Value for the money."

"The Luna Automated Cell Counter has brought cell counting to a whole new level. Don't know what I would do without it! It is super quick, convenient, and simple to use. I use it with the disposable counting slides which saves me so much time when doing my cell cultures, especially when I have multiple cultures to deal with. I strongly recommend for labs dealing with cell cultures."
