LUNA-II™ Automated Cell Counter by Logos Biosystems, Inc

"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 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."

"User friendly apparatus, beautiful design, many options, etc."

"The LUNA-II™ Automated Cell Counter is easy to use and helpful. It reduces the time we spend on different cell samples. Overall, It's a great instrument for lab."

"LUNA-II™ Automated Cell Counter was easy to use and counted cells quickly. Value for money was not expensive."

"I use it for my daily cell culture tasks. It gives consistent results throughout my study."

"It really helps my research since it is easy to operate and efficient. The consumables are a little bit too expensive. Overall, my experience of using them is great."

"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!"

"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."

"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."

"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."

"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."

"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"

"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 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."

"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."

"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."

"Very easy to use, the reusable slide is quick and easy to clean and load your next sample. Being able to increase magnification on the cell counter is great for instructive purposes."

"This compact, easy-to-use device is good for efficient quantitative cell processing. The accuracy of cell counts and the tools provide live visualization and the zoom allows different angles to be looked at. The service and the price can be considered competitive."

"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."

"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."

"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."

"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."

"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."

"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."

"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."

"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."

I can recommend the Luna-II cell counter, as it is very easy to use, takes up only little space , multiple cell-lines can be programmed in the counter, and the results acquired with the cell-counter are reproducible."

"LUNA-II™ counts fast and reliable. It saves me several minutes lab work per day. LUNA-II™ is everybody's friend in our lab."

"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."

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

"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!"

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

"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."

"Efficient, fast and true-to-life device for counting cells. The only negative point is the lack of choice of the "with or without blue" parameter when creating a counting program. Moreover, there is nothing on the home screen to know if the trypan blue parameter is activated or not and we must check each time, in the parameters of the device, the count with or without blue trypan before we do our counting. A small suggestion would be to have more on the home screen (top right accompanying the name of the selected program for example), a blue trypan icon checked or not to have a quick information on this parameter."

"Device is really easy to use. Providing a reusable blade is a real advantage when you have a very frequent use of the device, it reduces the cost of consumables. The data obtained is reliable and reproducible. Small disadvantage: for some lines, the device does not seem to count correctly (low cell concentration and very low viability obtained on LunaII compared to the results obtained in cell Malassez). Perhaps it is due to the fact that these cells are deformed base? For having the ability to use another cell counter of another brand, the count on the LunaII is two to three times longer. But the team and I are nevertheless satisfied with the product!"

"We've had this product in the lab for about 2 years now and I have to say it really improved the cell culture experience. It makes cell counting more precise, something we tested at the beginning. It gives accurate cell number, avoiding the counting by eye. Also, preparing samples and loading them is fast and easy, so you can count several cell lines in just few minutes. The after sales care have always been available whenever we had questions, which is always valuable. All in all, I am truly thankful we get to have this product in the lab, it really makes our work easier."

"This product is easy to use. The fact that one can use a reusable blade is an advantage in terms of cost when one line is to be counted. The results are reliable, we have compared them to those obtained in Molasses cells, against the concentration must be close to 1x10 ^ 6 cells / mL. I am very satisfied with this purchase, which is unanimous within the team."
