EVE - One of the Fastest Cell Counters by NanoEntek

"I think the Eve is great. It’s so easy to get accurate concentrations of cells. My results are also reproducible. The “more data” tab to look at cell diameter across the live and dead cells is very helpful! I love that. The only problem I have encountered is when I fix cells and go to viability counts, I get high viabilities (>80%) when all the cells are staining blue on the screen. I don’t know if I need to wait longer with the cells in trypan blue for fixed cells, but that has been an issue. Checking the same cells on the Countess gives me <10% viabilities."

"The EVE™ Automated Cell Counter is so simple and convenient to use! Fast cell counting and easy to understand viability measurements. A must-have in our lab."

"The cell counter slides are incredibly easy to use and very reliable. No more hemocytometer!"

"Very effective, and reproducible providing precise cell counting. Saves time and nerves compared to manual counting. It is very simple to use because the steps are reduced because equipment is ready to use."

"Gives a reliable cell number per ml. Gives total value, live and dead values, vability determination"

"Very fast and accurate value for money"

"Fast and easy to use. Simple to train new people on."

"EVE is an efficient, user friendly automated cell counter. Very easy to handle for everyday use. It gives reproducible results in a short time. It gives a nice summary of the cell size. This cell counter is perfect for basic!"

"Very easy to use with Trypan blue and the NanoEntek slides. The results are clean and it is made so mistakes or wrong results are easy to spot. So easy an undergrad can do it! No issues and been using it for a year."

"Easy to use and easy to handle. The result is similar to actual value. 사용하기 편하고 다루기 쉽다. 결과물도 실제값과 유사함"

"Very easy to use and gives quick, reliable and reproducible results!"

"The EVE cell counter is super easy to use, intuitive, and yields reproducible results. It’s great that each box of slides comes with a new tube of Trypan Blue! I love this machine!"

"The machine is very user friendly and gives accurate and fast result. It's really convenient to use. Makes things very easy and faster! Loved it"

"Easy to operate, good price, best quality. Will purchase more for our growing lab."

"Easy to calibrate, quick and easy to use."

"I don't struggle with this product to get what I want in the lab. It saves me time. Great product"

"It can effectively count the amount of living and dead cells Counting fast, high efficiency, high cost performance."

"It is a great device. A lot of time is saved compared to manual counting, since you only need to load the slides (disposable) and focus the sample. Settings can be saved in programs to standardize results and captures can be saved in a USB. Fully recommended to streamline your counting protocols."

"The product is very nice, the cells are counted much easier. It spends us a lot of time. Blessed to have this equipment."

"This instrument is extremely easy to use, but also the results are reproducible. I have counted the same sample in a considerable period of time and the variation is very small. Also is user-friendly and does not require a trained professional"

"NanoTek is a good investment with it's simple, easy and user friendly instrument, very much recommended in all cell culturing labs. It makes life easy while counting cells. I rely on my cell counts which are accurate and reliable. ''Its a paisa vasool instrument'' meaning that the instrument is worth every penny."

"Easy to use."

"It is consistent, and works very well for cells like hek293 or CHO that I h AB e used with it. It is much less useful for primary cultures of drg. Because these cells are dissociated from ganglia containing connective tissue and myelin, the sample of cell suspension inevitably has some amount of debris present in the viewfinder. The software counts a lot of non-cell objects as cells, skewing the results of the count. The search parameters to define size and roundness do help, but I have not been able to rely on the count."

"I use the EVE automatic cell counting instrument primarily to count embryonic fibroblasts and adherent immune cells, although we use it for a variety of other primary and cell lines. I am usually able to get consistent results when doing multiple counts from a passage. Comparing cell counts from this machine to manual, hemocytometer-based cell counting has, at times, yielded very different results, but for the most part, are pretty close to one another. I would say the only thing that lacks here at times is the machine’s ability to differentiate live cells from dead ones, depending on the type of culture. I’ve noticed that the focus can be pretty sensitive, so it wouldn’t be a bad idea to double count or supplement your counts manually if needed. Overall, the machine has been very durable, as we use it multiple times per day. The reliability of this machine is also quite fantastic, so long as you are careful with your counts. This machine has allowed us to move away from manual cell counting and use it in emergency-only situations. My overall assessment of this machine is that it is quite the luxury to have if you’re able to."

"The device is really worth its weight in gold. Precise counting of the cells, accuracy, everything is great. Indispensable in our cell culture."

"Easy to use and good performance"

"I love the product, I use it everyday to count cells"

"It is really easy to use. The results come really fast"

"The EVE provides all the basic parameters required from cell counting in an easy, fast and reliable way. The software in the equipment is very intuitive. The software in the computer to perform post -counting analysis stopped working after some time and I have not been able to get technical support to help me find an updated version."

"Very easy to use and efficient. However, the counting for dead cells seems not very accurate all the time. It always counts one dead cell for multiple times which makes the viability lower."

"Super easy to use, and accurate results as I’ve validated it my manual counting many times. It decreases time couting by 90%."

"This is a good product. Worth to have it in the cell lab."

"The counting device is very reliable and easy to use. I have never experienced any problems counting my cells and recommended the device to other lab groups."

"I am highly satisfied with using the Eve cell counter. First, its very fast, faster than what you would expect, maybe less than a second. Second, repetitive high accuracy result. Additionally other functions like focusing and zooming are easy, thats why I like to use it."

"Easy to use and fast, the slides never generated any bubbles compared to other brands. Counting is accurate, and perfectly appropriate for our common cell lines."

"The EVE automatic cell counter is very efficient and easy to use. It also gives accurate results. Thank goodness I got this, it is a must buy!"

"Fast and reliable. But however, the variation of result may be a little big if the cell concentration is low."

"We usually count multiple cancer cell lines for high throughput drug response experiments, the EVE has significantly reduced the time we spend counting the cells, so we can spend more time plating and analyzing our experiments. Moreover, the accuracy that gives us to know the viability of each of the cell lines improves our experiments. We love how easy it is to use, the low volume we need for counting, the fastness, and accuracy of the system."

"NanoEntek Cell Counter is one of the simplest instruments to use. You just open it with one button, insert a slide with your cells and click to measure. It has options to optimize cell size and change the focus. Using it is much simpler and faster than counting cells in a counting chamber. You will especially appreciate it when you will work with 20 cell lines at the same time."

"It is really easy to use and gives the results so quickly."

"Having been using this in our laboratory daily for the past 5 years without any problems."

"The Eve Cell Counter works great for our needs. We typically count using fibroblasts which seem to be a great size for counting on this instrument. We have also counted smaller cells such as b cells and gotten accurate results as well. The cell counter works amazingly for live cell counts, however the dead cell count is almost always totally off. We've tried configuring it but it counts dead cells, or vaguely dark areas, multiple times. You'll see several circles around the same "dead cell", and so it vastly overcounts dead cells. Since we don't work with unhealthy cells and typically don't care about viability as long as its 90%+, which can be eyeballed, we usually ignore the dead cell count and just use the live cell count. It's great for getting quick counts for plating, especially when you have many conditions which would be a pain to manually count. Price for the counting slides are great as well. Overall it's nothing fancy, and as long as you don't care about cell viability, then it will work great for your needs."

"The Eve counter is the easiest and most cost effective piece of equipment we have used for counting cells for our cell culture experiments. Eve only requires 10 uL of cells and provides both counts and viability estimates simultaneously. It has saved us time and money as well as standardized counting between users and cell types. I would highly recommend this product for scientists who value their time and desire consistency and accuracy in their cell counts."

"I think this machine is really useful! It's much easier to count cells and faster than counting manually. It will save you a lot of time. And it can also count dead cells and live cells. You can get your cells' viability. It's super useful!"

"We use this a lot for cell counting and to analyze cell proliferation! As cell counting is time consuming, this instrument makes it easier and more accurate than the traditional way! The result can be replicated with a different assay, so the results from it are believable. "

"A cell counter that is fast, user friendly and accurate. Because of the speedy reading, this equipment can also be used for cell viability assays, removing the risk of having human error and bias while counting."

"Great advice, cannot imagine our daily work without this fantastic machine. The EVE cell counter allows us to run a fast cell counting and we feel very comfortable with the results. Our students are super happy now to run cell counting experiments than before. I definitely recommend to have in the lab EVE cell counter!"

"We bought the EVE cell counter a couple of months ago. It’s very easy to count cells using this device compared to the previous one. I work on primary cells and it's really helpful for me as it saves time while counting cells which further helps me to maintain cell viability during cell culture and replating. Data obtained are reproducible. Another important feature that I like is it gives the size distribution as well as percentage viability of the cells."

"Super easy to use, only needs to adjust zoom to endure cells are in focus."

"It is very easy and user friendly. The result is accurate and reproducible. It is also fast and counts the cells in less than 20 sec."

"We use this machine across many labs for our cell-based research within the cancer drug development process. The accurate and reproducible cell numbers in the experiments are ensured by this machine, and thus enable us to perform reproducible experiments. The machine is used daily, and we particularly appreciate small volumes needed for the counting process, fast counting time, and intuitive use. One thing we miss at the moment/would like to see developed is a queue of slides, for the times when we count between 5 and 15 cell suspensions. But even without it, the process is extremely efficient."

"After using EVE cell counter, getting high quality and reproducible results is more easily done. It’s easy to use."

"I recommend such a cell counter, because it is very easy to handle, comfortable as it is not very large etc. Recomiendo dicho contador de células, debido a que es muy fácil de manejar, cómodo al no ser muy grande etcc."

"Count cells was a hell, but now you change it well. It saves us time."

"Since we got this cell counter we have no differences in the number of cells we plate. It’s really accurate and the false window is really low. I would recommend this product as the cell counting results we take are reproducible."

"The EVE cell counter allows the user to quickly count cells in the fastest and reliable way with high reproducibility between samples."

"It is really effective for cell counting and checking cell viability. I recommend this item. Be cautious when you adjust the resolution of your cell."

"Reproducibility 80%. Accuracy 80%. Easy to use 100%. I found a problem in counting if not focused properly, as there is no autofocus. I need to focus every time before counting."

"We have been using the NanoEntek EVE automated cell counter for counting mesenchymal stromal cells and neural progenitor cells for years. It gives us a fast, robust and reliable cell count as well as cell size distrubition."

"Cell counter is easy to use and the results are quickly given. Before counting the cells, you must specify the cellular parameters, e.g. size. Sometimes cells that aggregates easily are difficult to count or are counted together."

"Very easy to use, very fast, and reliable. After the count you can assess if the machine did it correctly - it offers a zoom "microscope" picture of the counted cells so at the very end you can decide if you trust the numbers. In my career, I used various methods, eg Drucker, Tucker and Neubauer chambers, and flow cytometry-based hemocytometer. I definitely prefer Eve, because it's fast and easy and it provides similar/identical cell counts as other methods."

"The cell counter is automated and simple to use. It works with autofocus and the results are reproducible. We are now really happy and very satisfied with the purchase."

"The product is really easy to use. Nevertheless, we have had some problems with the trypan blue which seems to not offer reproducible results. However, we use our own trypan blue and we have achieved reproducible results."

"The Eve Plus cell counted is very friendly to use. It’s simple, quick, and you can check which cells were counted or not easily with the screen. I highly recommend this product!"

"High-quality product. Used in the conduct of cell cultures. Easy to use, intuitive. Original design. Good value for money."

"Cell counter slides save time and effort."

"Simple machine but full results. If your are still doing manual cell counting, go and tell your boss to consider buying this one. Our lab life got so much better than before the day we bought this cute machine. We've been using this for over 4 years (purchased in Jan 2017) without any malfunction. Now it has become slower but it takes only 30~40 sec to turn it on which is very affordable to prepare your cell counting slides and mix with Trypan blue. Then just slide it in. No need to count with your naked eye. Just watch what it shows. It tells everything we need regarding cell counting experiments. These days we are doing single cell RNA sequencing which requires strict quality control of cell conditions. EVE counter is a great sidekick for our research. Recently we sent the instruments to the Korean vendor of this product to check its condition for scRNA-seq. The man who took care of the service was really nice and kind with super-fast response. (Who hired him?). He quickly sent a demo for replacement and after 2 weeks of the factory inspection, surprisingly, it turned out it's flawless. Let's see if it can be with me till my graduation. If you are considering buying this, just request a demo then think about it."

"It's very easy to use for cell counting! With this machine you can get high quality and reproducible results. It's also easy to manage and cheap."
