"This is a fast and reliable instrument. Definitively one of the best cell counter I have tried so far. I really recommend this product."

"We purchased the Logos Biosystems LUNA-FL cell counter to quantitate human T lymphocytes and other cell types. This was early 2020, so most everything was shut down due to the pandemic, but we needed a good cell counter for SARS-CoV-2 research. To test if the instrument would meet our needs, Logos shipped us a demo to try out. The machine is very easy to use, accurate, and provides lots of supplemental data beyond just cell number. The LUNA-FL cost a bit more than some comparable counters, but less than others. The sales support and flexibility was what really stood out and sold our lab. The disposable slides can get expensive when performing many counts, but that's a common refrain for most counters. To save on the costs of consumables, I recommend buying straight from Logos; reusable slides also exist. All-in-all, this instrument, and the support behind it, have met our lab's needs well. We're happy and without complaints."

"The LUNA-FL is a very compact, lightweight device with an intuitive user interface that only requires minimal training. We use it every day for live/dead cell counting and are satisfied with the results. Logos offers disposable slides for high-throughput but also reusable ones for smaller labs (with a little effort you can also reuse the disposable ones but you didn't hear that from me). Preparation of slides with AO/PI takes about 1 minute. The only downside was that the distributor of the LUNA in our country changed right after we bought the device, so no after-sales care from that side."

"We've had it in the lab for a few months and it is easy-to-use and saves a lot of time!"

"The automated cell counter is quick and easy to use for cell counting experiments. Being able to pop in my slide and get an accurate count of my cells really helps me save time and feel confident in my counts. I use this for both personal and a lab class that I TA for. It helps my students understand cell counting and cell viability."

"This instrument speeds up cell culturing, has friendly software and it is a very good piece of equipment."

"The Cell Counter is effective for allowing us to make better use of our time instead of using manual counting methods like the hemacytometer. There is some variability to the results, however they are for the most part consistent. The Cell Counter is intuitive in its interface and easy to operate with minimal training. One should be mindful of dilutions. So far we've had no problem (sourced to the equipment) and have had many instances of its reliable use."

"LUNA Automated Cell Counter is very convenient to use. The speed of counting is so fast and it's the primary reason I choose it."

In addition to providing quick and accurate results, it includes many customizable features for all of your cell counting needs."

"The Luna STEM Counter is very quick, effective, and accurate. We use the Luna STEM Counter on a daily basis and have run into no troubles for 2 years now. In addition we are a consumer of the Luna STEM Slides and AOPI Fluorescent dye, both of which are very inexpensive and extremely obtainable - with help from outstanding customer service. Definitely worth the money."

"The LUNA-FL Dual FluorescenceCell Counter really speeds up the process of cell counting and makes the job a lot easier and more productive."

"Before, we used another cell counting device, but the capillary clogged a lot, the cuvettes where annoying to use, the measuring time was 30+ seconds per sample and we needed a large supernatant sample. We made the switch to the LUNA 4 years ago and won't go back! The LUNA is fast and does not need anything besides trypan blue, slides and a small sample to work. It also lowered our counting operating costs immensely!"

"We use this instrument on a daily basis to count various cell types, including suspension and adherent cells. It is an easy-to-use automatic cell counter, which saves a lot of our time during cell seeding and especially when several people work in the lab. We use single-use catridges, but a rather expensive option of multi-use glass cartridge is available. In the instrument setting, one can adjust the parameters used to define viable vs. non-viable cells, such as size and roundness for more accurate counting. After counting, the user can highlight the viable and non-viable cells to check if the counting was correct. For it's price, performance, and convenience to use we definitely recommend LUNA-II™ Automated Cell Counter."

"We are using Logos' automated cell counter (Luna II), it's very easy to use and saves a lot of time. Within a fraction of minute we get most accurate and reliable result. It's very compact and lightweight."

"In our lab we do many cell based tests such as cytotoxicity or IF WB etc., and also we have blood samples from clinics so it was a lot of cell counting and calculation, after getting this small, cute device, we saved a great deal of time and effort and also money of course. The consistent and stable results make us feel this was a worthwhile purchase and will make us become a loyal customer as well! Just hoping the shape will be improved to an even smaller one in the future."

"This is invaluable for all of our cell-based assays, for all of our injection preparations, for all in vitro and in vivo departments, everyday!"

"This is a really valuable piece of equipment. I have been using various devices for cell counting for 20 years, but I haven't seen one as easy and accurate as this one. That's how good it is. What's more touching is that the price is satisfactory. I've already recommended it to someone else."

"Used to count living/dead cells after tissue digestion. Great service and easy to use product!"

Our lab members use this instrument very frequently every day. It has contributed more than we expected to our research."

"Perfect counter. We are using it for many cell lines. Easy to use, self explaning machine, that needs nearly no space in our small cell culture room. Fully comparable results to manual counting. Reusable or disposable slides. Switch it on and use it in seconds. Really helpful and time saving purchase."

"Just recently purchased the LUNA-II Automated Cell Counter. Love this cell counter. It is small, easy to use and very helpful. It makes cell counting quick and easy so I can pass all of my cell lines quicker, getting them done in a single day rather than two. I can also make better calls on split ratio since the LUNA-II lets me know how many live and dead cells I have and the percent viability. Data can be printed and collected on a thumb drive. So glad I was able to make this purchase!"

"The LUNA-FL™ Dual Fluorescence Cell Counter is very fast and easy to use. Our lab utilizes this instrument to count multiple cell types of different sizes; I much prefer it to a hemocytometer. The Luna is small and easily fits on our bench top. The counting and viability data is accurate and reproducible."

"The cell counter is easy to use, great for teaching, and very accurate most of the time. Use the bright field setting and the fluorescent setting most frequently and am satisfied with both."

"The equipment is very reliable with great accuracy and precision. It is user friendly and it is easy to use. In my former lab, we counted cells via microscope using the counting chamber with which it was very difficult to identify dead cells. With this equipment my job has been made easy."

"It's a very easy to use cell counter, the results are reproducible, it has the option of calculating dilutions for your desired cell concentration which is pretty useful. The disposable slides are the best option but we also have the reusable slides and the only issue is that it's delicate so you have to be careful using it."

"Great product for the price. Easy to use and quick. It has made it possible to do routine cell counting and viability testing, that were otherwise very time consuming. There are few settings to play with, but they are enough to tune the machine to our needs, mainly counting HEK293T cells and viability by trypan blue staining. We could get consistent values between the machine readings and manual counting under the microscope."

"A great cell counter, love how easy it is to use. The interface is simple and easy to use. Easy to calculate dilutions etc too."

"From 10 ml whole blood it is estimated to obtain roughly 10 million PBMCs. When counting with the LUNA FL with the AO/PI stain, we indeed see total cell counts approximating what we expected from what is known. This system in combo with this dye mix offers a fast, reliable solution to count PBMCs."

"Using the automated cell counter, I am able to count a large number of cells in the counting chamber compared with manual counting in a hemocytometer. This might lead to more accurate cell numbers but I don't really need that accurate of a count in routine tissue culture work. The live vs dead function is not useful for me because the dead cell number is usually quite low when passaging cultures."

"Simple to use with a clean interface. Recommended for labs"

"We are a research lab that does in vitro and in vivo immunological studies. Viability and accurate cell counts are extremely important to our studies. The Luna FL is extremely user friendly and easy to switch from brightfield to fluorescence to GFP. The option to use a resusable slide also makes this instrument cost effective when only counting one sample. It takes up very little bench space and fits in our small tissue culture room where space is a premium. The ability to demo both the Luna instruments side by side for as long as we needed was a must for us and Logos allowed us the time and support to test all counting methods completely."

"This instrument is easy to use and I can count PBMCs or cell lines with reliable results. The counting is quick and practical. I am satisfied with this purchase."

"This instrument has been indispensable for our single cell RNA-Seq sample prep process. Most of our samples are primary cells that have a high potential for debris and cell aggregates, which make traditional hemocytometer/trypan counting difficult. Dual fluorescence counting has greatly improved our accuracy and reliability. We also love being able to digitally archive the images/count reports for later reference. The instrument controls are intuitive and allow for manual focusing of the cell images. Our service rep has been very quick to address our after-sales needs. The Luna-FL is the most affordable instrument that meets our needs (and often exceeds them!). Would recommend."
