DeNovix CellDrop™ Cell Counters by DeNovix

"As a researcher in micro-sample quantitation, DeNovix CellDrop™ Cell Counters products meet the needs of today’s laboratory scientists— instruments that are smart, simple, and robust. It combines their extensive expertise in micro-sample analysis with an in-depth understanding of real-life applications to deliver the latest in UV-Vis and fluorescence instrumentation. They have utilized a unique technology that allows a sample to be pipetted directly onto an optical measurement surface. The system uses inherent surface tension to hold a micro-volume sample in place during the measurement cycle. Once the measurement is complete, the surfaces are simply wiped with a lint-free lab wipe."

"I work for a Forward Biolabs member company and use the Trypan Blue mode in the CellDrop to count cells for cell culture passaging. The program is intuitive to learn and very easy to use."

"Easy-to-use cell counter that is less wasteful than counters that require abundant consumables. Several modes of use and easy to maintain."

"Easy to use, reproducible and reliable results. Made our life easy in counting the cells. Nice addition to our lab."

"This machine does not need consumables, saves the cost of the experiment, and allows us to complete the experiment more efficiently. The result is reliable, and students and teachers like it very much."

"User-friendly equipment with a caring and responsive customer service team."

"Easy and simple unit. Gives us quick results and saves money. Recommended."

"We have gained a better way to do cell counts on our cultures rather than doing individual counts on a hemocytometer, which is what we were doing previously. The maintenance on the tool has been very easy so far in the few months we have been using it. For lower concentrations of cells, we do have to clean the platform between each count with ethanol, as the prescribed dry wipe leaves behind a residue from the previous sample. The brightfield app has had the best reproducible results, but we have seen some background staining when using trypan blue on our cultures, especially on low cell density samples. Those results have required a review of the provided images to double check the seemingly higher counts."

"The product is really effective. We conducted tests by comparing the results of cell counting by the equipment and using a Neubauer, and we found no significant difference. It is very easy to use. Just turn on, choose your protocol and apply the sample. The only negative point until now is that the "Home" button is a little too close to the "focus" button, and sometimes it happens that you click Home instead of focus, and you need to choose the protocol again. When it is a protocol from a profile that is secured by password, it is a little bit disturbing."

"Easy to use cell counter compared to others."

"Very easy to use. No need to read the manual."

"Cell counting with Trypan is accurate and reproducible. Counting CAR-Ts with AOPI on the CellDrop produces significantly lower cell counts and viabilities compared to other automatic counters and manual counts. Software is easy to use. Cleaning off the sample pedestal thoroughly after each use adds time to the process, but eliminates the cost of disposable slides."

"The best cell counter - easy to distinguish between dead and alive cells using trypan blue. Makes the job so much easier. Fast and reliable results. Simply perfect."

"It's easy to use, just clean with dry paper. Saves our time for counting cell number."

"It is easy to use. Cleanable with just dry paper. Saves us time counting cell numbers."

"Currently used in our lab for testing microalgae. Great and reliable results every single time. Easy to use software makes us enjoy spending time in the lab. Great technical support from the manufacturer. Best value for money and definitely the most popular instrument in our lab."

"High quality and easy to use"

"It is easy to use and saves time in the lab. "

"Very easy and convenient to use. Not using consumables has saved us a lot of money. The device also measures very quickly."

"Very pleased with this cell counter! Compact for benchtop and easy to use with no consumables needed. Excellent customer service and guidance whenever required."

"It is effective, easy to handle, and gives high-resolution results."

"It is a fairly robust and easy-to-use device. Very intuitive and functional for its application."

"Results are very accurate and reproucible while analyzing microliters of sample. It's very handy to carry. Need some sort of improvements to the s/n ratio."

"Easy to install and use. Introduction/installation session (via zoom during COVID19) was excellent and provided opportunity to ask any questions and troubleshoot. Simple to use and clean/maintain. Good menu system and sensitive touch screen even with gloves, enabling seamless work in tissue culture. Settings adaptable to different cell types/cloning work in our lab."

"Saves time for huge experiments, high accuracy level."

"Simple, fast and reliable for cell counting."

"The machine was excellent, but it was difficult to apply it because our cell types varied in the area."

"Easy to count cells with. Small problem with distinguishing netween cells and debris."

"It is very easy to use. very well optimized for users. One of the best features of this machine is that it doesn't require any more consumables (eg. counting chips) I strongly recommend this machine to other researchers if you guys want to increase efficiency of your reseasrch."

"We count cells prior to CyTOF and during sample prep. It is accurate, easy to use, and lets us evaluate live/dead, debris etc. No slides needed and it's fast."

"In general, the cell counter is working very well, giving reproducible results without needing to use additional consumables or reagents. A counting protocol can be customized to adapt to the size and properties of different cell lines achieving good precision in the results. All parameters and count can be exported by USB in a very friendly way. We experienced for the first time after 6 months a problem with the mechanical arm which closes the counting chamber. Normally the screen warns you to close the arm to be able to count but this message sometimes does not disappear even lowering the arm itself. Hopefully it's not something persistent but we were surprised to have this kind of technical issue after such a short period of usage."

"Very easy to use. Very good cell size determination to moniter cell quality. However, it's too expensive compared with machines from other bands. We only need half the price of this to get a new one."

"Celldrop is an excellent cell counter option, in addition to the data being reproducible it does not use consumables or slides. This means that with a small sample volume, I already get reliable results. The equipment is very intuitive but even in case of doubts, customer service is always available and the manual is very explanatory. For not having consumables the investment value is very worthwhile."

"The equipment is very good. The fact that it has no consumables and uses small sample volumes (microliters) is an important differential. Super useful for experiments where counting many samples is critical."

"Results are reproducible. The equipment is easy to use."

"It's basically a programmed microscope slide to take an image of stained cells and does the command. It is very easy to use, we use it for cell counting during cell culture making passages, and it counts the cells fairly quickly. I'm the end user so I don't know about the after-sales care, but the training was very useful. It's a bit expensive for a machine with only one function, and I don't know whether it has any other functions other than imaging the stained cells."

"High quality, easy cell counting and very fast. No need for extra tubes - we can just inject 10 ul."

"We had the instrument on demo about a year ago. Overall, the design is great. The machine is friendly, fast, and far more sensitive than those of competitors. This the only system of this type that doesn't require counting chambers. Operation is simple, somewhat similar to the NanoDrop or NanoView. The big disadvantage for us was that data on fluorescent intensities could not be extracted into the file. The system allowed us to plot a graph on its built-in screen (so data was there), but there was no option for data export."

"Easy to use. Reproducible cell counts. Increase efficiency of workflow."

"This is really easy to use, it does require some optomization to find the right counting conditions for your individual cell type. We are counting single cell suspensions from lymph nodes, spleens, digested tumor, and resuspended tumor cell lines thus far. Its very user friendly and durable, which is great when you have trainees in the lab. It also normalizes counting between multiple members of the lab. I looked at multiple counters when setting up the lab, this was the only one I found that does not require a continuing purchase of consumables, which was a huge selling point for me. We haven't actually used the after sales care, so I can't speak to that but they were very responsive during the demo period. We also haven't had any issues with the counter yet and it gets pretty frequent use (40+ samples to count per experiment several times per week)."

"The DS-11 FX+ is very easy to use, takes quick samples, and takes up very minimal sample volume. It is a great design and the simplicity is outstanding for such a powerful machine."

"This cell counter replaced our older Countess Cell Counter and is easier to use and more accurate. We are a 20+ person lab and the CellDrop gets used often with no issues thus far. Highly recommend this product."

"A very reliable and accurate device. Saves the cost of slides and is user-friendly."

"The ease of use and the ability to count cells much like loading a hemocytometer and not requiring disposable cuvettes/counting chambers makes this a real asset to cell counting."

"It gives you accurate readings, which in some cases, is the most important factor. We do experiments in which every cell maters, and with this machine we can get the accuracy we need."

"CellDrop has a great overall design, a lot of output, the ability to connect to WiFi, send emails directly without USB, and constantly updated versions are awesome. High cost performance, simple operation, experimental results are also very accurate."

"The CellDrop from DeNovix is an instrument that facilitates any experiment using cells. It is remarkably easy to use, only need to see it done once to get the idea of how to use it for yourself. The CellDrop itself does the work for you and doesn't require many additional steps to get to the point of use. The CellDrop also doesn't require recalibration in the same way that other machines often do. The CellDrop in my lab has certainly seen plenty of use, but doesn't require much after-care to maintain its reliability. The value of the CellDrop is high for the cost, making lab life easier overall. Though the CellDrop does sometimes have a hard time distinguishing between live and dead cells, no machine is perfect and the researcher is there for any final checks. Overall, the CellDrop gives a good idea of what you have without you having to spend a lot of time counting and straining your eyes."

"The CellDrop has saved our lab time and money and the company we purchased through, FroggaBio has been there for all questions/concerns from end users."

"Highly recommended and very cost effective. It is needed in every biological department."

"This product is so smooth to use. Long life and durability."

"A neat, robust machine which performs consistently without fuss. It's really great to be able to store images to review previous results later."

"The counting process is easy and fuss-free. It removes the need for plastic slides from routine cell counting. This eliminates disposable costs and reducing the environmental impact of scientific research."

"The machine enables the fastest cell counts, viability assessment, and GFP transfection efficiency measurements across the widest range of cell densities, cell types and applications in only seconds."

"Our brand new CellDrop was just about to arrive when the lab was shut down due to Covid-19. During our week demo trial, we easily used it to count a variety of cell types. The salespeople were very helpful, and a DeNovix scientist helped me to establish my own counting protocol for iPS cells. Considering the multiple applications of the counter, and the lack of consumables, it's definitely worth the price."

"The Celldrop is very nice. User-friendly, quick, accurate and consumable-free."

"The CellDrop has made our single-cell genomics work much more reproducible. We have several users in the lab that need to quantify cells or nuclei for droplet-based single-cell RNA-Seq, and for this, cell/nuclei concentration really matters. Before the CellDrop, our hemacytometer counts differed a lot between user, resulting in a lot of variability in our sample yields. Now that we're all using the CellDrop, there is far less variability between users. Also, the CellDrop is fast and easy to use, is highly accurate, and cuts down on consumable use/single-use plastics."

"Relatively cheap, solid instrument. No consumables, works very well with bright field, fluorescence, trypan blue counting. Every cell room should have one!"

"Easy to use, excellent image clarity of cells to be counted."

"Very ease to use and no need to use slides. Accurate cell viability using Ao/PI assays."

"Self-explanatory, robust and easy data transfer."

"Analyzes samples directly and gives results in very short times."

"The CellDrop is a very useful cell counter."

"CellDrop has great accuracy without plastic disposable slide which is good for the environment."

"This automated cell counter works without any strips and the cell can be seen in real time. Right from demo, installation and after setup service, we have had a good experience."

"This product is really easy to use! the interface is very easy and I never have problems with it."

"I have been using CellDrop for four months. First, it is convenient to order samples, and the results are given quickly. The next measurement can be made after simply wiping the detection table, and no consumables are needed during this period, which is very environmentally friendly and saves a lot of costs. It is always a good news for cell researchers."

"It is convenient for us to use and the service is good. When we have any problems, the enginner will come soon to solve the problem."

"CellDrop has been used in our lab for three months. The engineers who did the installation training explained very patiently, and it was also very convenient to use. Just took a few seconds to give the results and there's not need for any consumables. Convenient and environmentally friendly, summary is one word - great。"

"The accuracy and repeatability of CellDrop is good. We do not have to count cells by our eyes. It is so good."

"CellDrop has a great overall design, a lot of output, the ability to connect to WiFi, send emails directly without USB, and constantly updated versions are awesome. High cost performance, simple operation, experimental results are also very accurate."

"Our laboratory is doing research on tumor drugs, so we have accuracy requirements for cell survival rate results. We purchased the CellDrop and the results are very accurate. The results list gives you a lot of useful information, it's easy to use, and it doesn't cost you anything. It's a great device."

"We bought the celldrop white model, which is very beautiful in appearance and easy to operate. Results are given quickly and accurately. After-sales engineers are also very professional, there is no reason not to love it."

"We do gene sequencing in our lab, so we have to pay close attention to the cell agglomeration rate. The CellDrop can be accurate to the number of cells with two or more cell agglomerations. This analysis is necessary for us."

"As not many people participated in the installation training for the first time after our purchase, the engineers took time to give us a second round of training. The service is good, the results of multiple measurements from the same cell samples are not very different, and the accuracy is very good."

"The results of cell count can be directly generated by histogram, which can give more intuitive result analysis."

"Counting results can be exported to image format, PDF format, CSV format and other formats."

"When counting the fluorescent stained cells, pictures of the fluorescent cells can be visually seen."

"The diameter of the counted cells can be set to obtain the most accurate count result."

"Cell count results can be directly obtained from the average cell diameter."

"One instrument can count bright field cells and fluorescent cells."

"Incredibly simple to use, versatile, and accurate. The sales team and scientists behind the machine have been helpful from day one."

"The accuracy and repeatability of the results were very good."

"Wipe off with paper towel after each count, easy to operate."

"Celldrop FL is very useful for cell counting. We have lots of cell lines to incubate. So counting cells is a huge part of our daily workload. We discovered this unit st s conference, we asked for a demonstration and felt it was easy to operate and got the result quickly."

"CellDrop FL is very useful for cell counting. We have lots of cell lines to incubate, so counting cell is a huge amount of work each day. We discovered the unit at a conference and we asked for a demonstration. It's easy to operate and gets the result quickly."

"CellDrop cell counter is the first unit we have seen that does not need use slides. It is easy and simple to use to count cells. The result is so quick and saves us time. No disposable slides leads to money savings."

"We focus on single cell sequencing. We need an accurate cell counter to help us adjust the cell vitality. The CellDrop has a high resolution screen and I can see the cells very clearly."

"CellDrop cell counter is the first unit we have seen that desn't need slides. It is easy and simple to add cells into. The result are so quick and save our time. No disposable slide - saves our money."

"I bought this cell counter and I teach 30 students. I think slides are too expensive and I have to pay for the slides when my students use them. CellDrop BF does not need slides so it saves our money."

"This CellDrop cell counter is the first unit we have seen that does not need the slide. It is easy and simple to add the cell into and the result is so quick and saves our time. No disposable slides saves our money."

"Great little cell counter. No consumables and a pay per use option make for a product fitting cash-strapped labs. Good cell recognition, fluorescence detection and reliable counting."

"Super easy to use, no slides or disposables of any kind. Easy and very user friendly interface. The only drawback is the small sample size that it actually counts."

"This is just what we were looking for. Simple to use, cell counting parameters can easily individualized to cell type and situation. Readings can be stored. Best of all, there is no need for consumables other than pipette tips which is kind both to the environment and to grant budgets."

"The cell image can be seen directly on the screen, and the counting results are more reliable."
