LUNA-II™ Automated Cell Counter by Logos Biosystems

"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!"

"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."

"Really easy to use with great results. Love the auto focus feature."

"The instrument is easy to use. The ability to calculate dilutions is useful and the protocol saving also allows for multiple cell/experiment optimization. The instrument is light which means it can be pushed back when inserting the counting slides. The round top means that there is no surface to weigh it down for a DIY solution to this."

"The procedure is quick and easy, and this gives you pretty accurate results. Sometimes the autofocusing is less reliable, but I'm still going stick with this instrument forever because it saves me so much time. Using it together with the disposable counting slides which the company provides makes your cell counting experience far less stressful. It would be even better if the data saving and printout function were more useful."

"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!"
