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."

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."

"It is a very nifty fluorescent cell counter. Very easy to use and with high reproducibility. Many useful functions for gating, cell size measurement and for counting yeast. I have used other counters but this one surpasses them all. We are very happy that we introduced it into our lab. Highly recommended!"

"It's very easy to use. I get high-quality results everyday. I recommended."

"The Luna works very well for counting cells using trypan blue. It is able to recognize live and dead cells in many different types of cells."

"LUNA cell counter is a really easy to use product that allows precise and reproducible counting of cells. The instrument has an extremely user friendly interface and it speeds up workflow during cell culture. I have been using it for more than 2 years and the machine still works as precise as the first day. Highly recommended."

"Until this machine was used, the cells were directly counted and observed under a microscope. However, after using the Luna-FL Dual cell counter, we were able to save about half the time and get accurate results. Very easy to use which is also an advantage of this machine. I recommend to everyone!!"

"The LUNA II cell counter is a fantastic product that has allowed me to create reproducible experiments within my cell culture. The instrument is extremely easy to use with a user friendly interface as well as appropriate complementary instructions online. The machine has never had any issues or faults after over a year of heavy use and as such I have recommended it to other labs with heavy tissue culture usage!"

"Very easy to use and packaged into a much smaller size than its competitors! Gives consistent and accurate results particularly for cell size which is essential for our work on insect cells. It is also able to detect very small mammalian cell lines which has proved to be invaluable. The liquid lense focussing system is instantaneous and requires very little manual adjustment."

"I am satisfied with this equipment. it is very easy to use."

"It made it easy to be in the lab with good experience and high quality, reproducible results."

"Very good product, excellent price, seller recommended"

"For our experiments, we use a lot of fluorescence cell counting. This instrument definitely helped us reduce the time we spend in achieving the results."

"Extremely reliable and useful. The ability to look at live/dead using the AO/PI stain gives the opportunity to ensure the correct cell concentration is being measured."

"This is great product and saves a ton of time in the lab. I previously used a hemocytometer for all of my counting needs, however with multiple stem cell lines to work with this proved to be quite time consuming. The cell counter not only saves time, but gives accurate and yield consistent counts between cell lines. Great product!"

"Easy to use and intuitive. Straightforward operation and consistent results"

"Works easily. We like this labelling and try to do work with 3D culture"

"The cell counter is very easy to use. It also adds speed to the process of cell counting, and accuracy that cannot be achieved by manual counting. We love it!"

"The Luna is easy to use and it gives reproducible results between cell counts. Moreover, it saves me a lot of time as each count is very fast and accurate! It is a good product to have in a cell lab."

"Easy to use. Once you turn it on, it is ready to use, so no warm-up waiting. It counts cells pretty fast, in less than a minute. One problem is that for cells that strongly aggregate or are clumpy, readings are not accurate."

"The Luna II Automated Cell Counter is easy to use, quick, and accurate. Our lab's previous automated cell counter frequently crashed and was unreliable; however, we haven't had any problems with the Luna-II. Overall a great product."

"I like this product. The machine is so good and accurate. I always check the results with manually counting and the results are consistent."

"Great product, I use to count cells for ELISPOt and flow studies and Logos has helped me so much. I can do more than three sets of the experiment at the same time each day due to the using Logos system."

"We have been use the Luna Cell Counter already for years and its ease of use and reliability make us happy users."

"This is a very simple automated cell counter that is well worth considering. We count cells to set up experiments with a consistent number of input cells and to express the resulting data accurately."
