LUNA™ Family of Automated Cell Counters by Logos Biosystems, Inc

"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!"

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"

"Good and easy to use cell counter, in the upstream process development,"

"The LUNA II Cell Counter is very easy to use with high reproducibililty, limiting inter-person variation."

"The Luna Cell Counter is easy to adjust and to use to obtain reproducible results. The high-resolution quality of the bright field and fluorescent images allows efficient and quick analysis of the cell count and cell viability. Once the parameters are set it is possible to obtain a robust read-out independent of the cell morphology. We use the Luna-FL Dual Fluorescence Cell counter every day and it facilitates fast and user-friendly application. It is possible to save the bright field and fluorescent images on a portable drive for further quantification."

"Fantastic lab instrument. Very easy to use and precise. Results are very reproducible. Strength points: storage of previous results; loading of different protocols (pre-set or customized, depending on the cells used); calculation application available."

"It is a really nice instrument to measure the amount of cells. It gives really quickly results."

"It is very useful to count quickly, in comparison with the cell of Malassez. It also allows you to have the number of dead cells and a living / dead cell ration. I highly recommend this product!"

"Very practical to use and very precise! In transfection procedures it's very helpful and speeds up our experiments a lot. I'm loving it!"

"Easy to use, the slides are useful and it saves a lot of time when I have to count my cells! I use it with trypan blue."

"Cell counter has a really nice display, is small so it does not take a lot of space. It is light and the person who came to show us the LUNA Cell Counter was really attentive and helpful."

"This cell counter is much easier to use than others. The user interface is fairly intuitive and allows you to customize your settings depending on cell type. You have live imaging to confirm your threshold settings as well. Lastly, I love the fact that you can use reusable cell counting slide."

"The LUNA-II™ Automated Cell Counter is a very useful and time-saving tool when high numbers of cell samples are to be counted. Former counts can easily be re-shown and different protocols can be saved, depending on which cell type is counted. The zoom-function also allows to easily distinguish between different cell types (according to their size) and viability state of the cells. All in all a very worthwhile tool for any cell culture Lab."

"I work with the LUNA™ Automated Cell Counter and the LUNA-II™ Automated Cell Counter, they Both work like a charm. They are easy to use, count fast and are nice and compact. although the scrolling function in the review menu sometimes is a bit annoying to use (with both devices) I am very glad we have them."

"Using the LUNA-II Automated Cell Counter makes cell counting fast and easy! The device is small, but thanks to the big screen with a clear user-interface, all the necessary parameters can be easily adapted."

"I use it daily for cell counting. It is easy to use and fast to get accurate/reliable results."

"The cell counter is very user friendly, and provides reliable/fast cell count and cell viability. The cell counter is useful when you need to count a large number of samples in a short period of time."

"The device is very easy to use. It also does not take up much space on a lab bench. The touchscreen is high quality and is very responsive to touch. Cell counting data is very accurate, even with primary cell types. Would recommend."

"It's very easy to use. If the cell counter had a Japanese version too, it will be better."

"The LUNA-II provides rapid and accurate cell counts. We often rely on the LUNA-II when processing many samples at a time. It helps to reduce sampling error, reduce processing times, and improve counting accuracy. The LUNA-II has built in calculators to help with achieving wanted cell concentrations (for if you are feeling extra lazy). Overall, this product works and intended and is very easy to use. A+ in our lab."

"Very easy to use and fast. The cell viability is accurate and I am able to distinguish cells from debris (leukemic cell lines)."

"I am the lead lab technician for a clinical laboratory specializing in ELISPOT assays. The LUNA-II brings fast, accurate, and consistent results, perfect for a high throughput lab. We are a start up company and funding is limited, so the affordability of the LUNA-II was a huge plus. Reusable slides can be purchased and trypan blue is very affordable, making the running costs next to nothing. The instrument itself is very easy to use and setting adjustment allows you to set your parameters to exactly how you need them. This instrument is a must have for start up companies who need fast and accurate cell counting."

"The LUNA-II™ Automated Cell Counter is very easy to use and definetely worth it for any lab which needs to count their cells. It saves much time counting cells and is very precise. By setting the background and changing the counting program (which can be saved) for each cell type that is being counted, the cell counts become very sensitive and precise. Really easy to use, also with gloves on."

"Super accurate and far faster than the haemocytometer, helpful for dilution calculations too"

"There's nothing harder than counting cells. You're good until 10, but then it's easy to lose count. But NO MORE. This automated cell counter counts your cells and saves you from having to spend your time doing such archaic things as counting to two million in increments of 10. Flawless design and execution."

"We bought cell counting for our lab experimental use : LUNA-II™ Automated Cell Counter and cell imaging: CELENA® S Digital Imaging System and working with these instruments are an amazing experience. I would recommend with highest rating to all aspiring scientists out there."

"It's a compact device useful for cell counting but the camera and software can be much far better in this area of time as we have better resolution camera that can be fancy and much useful with cheaper price. In comparison to other cell counting device, it is comparable. There is a negative point of the design of the slide for cell counting about the depth that can focus better on nuclei counting. It can be faster and much reliable on the stability of the camera focus point for the next usage with the same cell line."

"This machine is one of the best .Easy to use and in most cases accurate, rarely get faulty as all the components are adequately packaged and gives results within few seconds."

"Using this equipment has made work much faster. The quality is dependable and can be trusted. It is good value for the money spent purchasing the equipment."

"Our lab uses the LUNA Automated Cell Counter in cell culture to count a variety of mammalian cell lines. We find that the cell counter has user friendly interface. Furthermore, it's very efficient and convenient to use. Since using the cell counter, the time taken to complete experiments has absolutely reduced."

"The Luna-FL Dual Fluorescence Cell Counter is one of my favorite machines in our lab. It lets me acquire cell counts so quickly so I can go on with my bench work. Not only are we able to count but we can look at other statistics like viability and average cell size with just the push of a button. The best part about this counter is the accuracy. I am able to reliably count every cell line that I put in, and am able to do it again the next day. I'm so glad we have this system in our lab because counting with trypan blue would take much longer! Overall, I would recommend this product to another lab that is doing a lot of work with cell lines in order to get a quick and accurate count."

"It is very easy to use this cell counter and it gives accurate values for the cell lines that we are working with. Great value for that price and that is why we are switching to this now."

"Our lab (Louisiana State University's department of Civil and Environmental Engineering) bought the Logos Luna II cell counter for the purpose of counting amoeba and measuring its viability after disinfection experiments. It has been incredibly easy to use and does its job well (and honestly has saved me tons of time that I can devote to other graduate student responsibilities). Not only has it helped me count my amoeba, it has helped the other grad and undergrad students in our lab for counting E. Coli. Thanks!"

"A very easy to use and accurate automated cell counter. This machine has improved my working quality of life! Compared with its competitors there was only one choice."

"In our lab at ITREN (DKU, Cheonan, Korea) we bought cell counting: LUNA-II™ Automated Cell Counter and cell imaging: CELENA® S Digital Imaging System and working with these instruments are an amazing experience. I would recommend with highest rating. Thanks."

"The Luna-FL is an extremely easy device to use and very user friendly. With many different modes available, it is certainly a useful tool in the lab. Our service rep is extremely responsive and helpful to our needs and questions. Highly recommend!"

"This product has a great user interface and is simple to use. I figured out how to use it and and took my first reading in less than twenty minutes."

"Luna cell counter is easy to use. Compared to the hemocytometer, cell counting is fast, and it gives % viability and size of cells which is very valuable info when working with different cell types."

"Great value and time effective that which makes this product stands out among other"

"We purchased this cell counter for our busy tissue culture facility. We needed a machine that is easy to use, fast, provides good reproducible results and offers the possibility to save funds on consumables by using re-usable counting slides instead of disposable ones. LUNA-FL has all these features. The interface is user-friendly, the counter is easy to use with minimum training required and the results are almost immediate, clear and very reproducible. Moreover, users have appreciated the fluorescence function too. It gives a very quick and clear idea of the efficiency of transfection experiments. The possibility to use a re-usable slide with this counter has reduced our expenses towards consumables by an incredible amount. In general, we are very happy with our purchase. A final note has to be made for the incredible support of the customer service: we had a very useful demonstration of the machine, which was left at our facility for a month for trial, without any obligation of purchase. We had an initial big discount for the purchase of two machines, which included two re-usable slides free of charge. When our re-usable slides broke, Logos was upgrading the design and in the meantime we were offered disposable slides free of charge. We have been using the upgraded design for months now, without any problems."

"We use LUNA-FL cell counter for analysis of mouse tissue preparations and primary cell cultures. Our samples include: lung homogenates, bronchoalveolar lavage fluid, T cells culture, etc. Acridine orange/propidium iodide dual staining is particularly beneficial for evaluation of samples contaminated with red blood cells. This approach is fast (analysis conducted immediately after addition of dyes) and more precise than methods utilizing trypan blue staining. Wide detection range and availability of re-usable slides are another advantages of LUNA FL. Major disadvantages include: no internal memory, only one USB port - precluding simultaneous use of pendrive (for saving results) and printer, long-lasting saving of results, lack of automatic focusing."

"We receive great results from our Luna and they are more accurate than using a hemocytometer. It is also a lot faster than using a manual count since we do not have to do any calculations with it."

"Very accurate results provided by machine. Multiple cell lines can be used and the counting slides are available at an affordable cost! Value for money and precision guaranteed!"

"Our Luna Cell Counter was having some issues right out of the box. I communicated this to Logos and within the hour, I received a call to help troubleshoot. After attempting to troubleshoot and realizing the attempt was futile, Logos offered to send a replacement instrument within the week. I was extremely impressed by the customer service and I would absolutely buy from Logos again. The company takes pride in their instruments and was professional, courteous and fast to help!"

"It is simple and easy to use. Consumables are easy available. The results are reproducible. we have multiple of those units."

"We are using Luna-FL for counting mostly insect cells during the maintenance and expansion of the cell cultures. It`s operation is very straightforward once the settings are customized according to the cell type. Compared to bright light, fluorescence counting results in much more accurate (up to 10 million cells/ml) and reproducible results. With reusable slide, we don’t have to set focusing every time. It takes a minute or so to get the cell count and viability. Just in case, we always check the tagged cells under bright light and we don’t see any unlabeled or mislabeled cells, independent of cell size or cell clustering."

"The Luna FL's strength is in the viability accuracy, as well as being able to differentiate aggregated cells from single large cells due to the nature of the dual fluorescent dye. I use this machine constantly with cell culture and its speed, ease of use, cost, and small footprint were the major factors in purchasing this over another fluorescent counting option."

"This machine is very precise, I can count very few cells after cell extraction from the biopsies, I also used this counter to plate after transfection so I need to have a precise number of cells, the counting is very quick and you can count different type of cells without effort. Is very practical because you can register your counting or print for report, and also you can see the cells with the screen."

"The cell counter LUNA FL is remarkably easy to use, fast and reliable; with a reactivity of the after-sales service. We are totally satisfied of LUNA FL."
