"We love the flexibility, diverse functions, and intuitive touchscreen!"

"Very easy to use, reliable, and accurate. After turning on the machine, starting the application of interest and measurement is very quick. Data transfer is easy. It uses very tiny volumes and saves a lot of samples."

"Very user friendly and gives quick and accurate results!"

"It is much faster and easier to use than the old equipment we used to use."

"We purchased this instrument for development and validation of cGMP methods of nucleic acid quantification. The results so far have been stellar and we are continuing to expand our method roster with this instrument!"

"I have been very impressed with this unit. It is very user friendly and takes very fast readings. It also has incredible accuracy and repeatability."

"I had only used the Nanodrop before this. But the DeNovix is comparable and works great."

"We had the chance of testing the DS-11 series spectrophotometer/fluorometer before purchasing it. The different people working with this equipment were really satisfied with its quality, reproducibility, and ease of use. Acquiring it was an easy decision. Also, really happy with the customer service."

"A fantastic machine. The DS-11 FX+ is able to quickly measure DNA and protein concentration. Of course, the easy thing to do is to compare this to the ThermoFisher Nanodrop. The Nanodrop may be fast, but the DS-11 FX+ is even faster. The DS-11 FX+ blanks in a couple of seconds and gives sample concentration readings in one or two seconds. It also gives more precise readings (three decimals instead of one when measuring DNA concentration). The DS-11 FX+ also seems to be more accurate and consistent when giving protein concentration readings. Best of all, I have yet to see a broken column error or bubble error. My lab ordered one for everyone to use and now I am choosing this machine every time I need to quickly measure concentrations. One last comment that I have is I like how it comes in fun colors. We have the Fire Red color and it looks like a race car and I think it is fun."

"I very often achieve high quality and accurate results in comparison to other equipment my lab has used in the past."

"Straightforward and easy-to-use application."

"I'm mostly posting this review because I'm so delighted with how easy this spectrophotometer was to set up, get online, install updates and get users trained on it. I work with many more complicated instruments and setting this up was a rare, absolute delight to unpack and get using. Looks like its maintenance will be minimal, which I also appreciate."

"Device is very easy to use, with ready to use apps. Measurements are reliable and very fast. All you need in the field of Molecular Biology."

"The product is very easy to use and takes up very little space on the benchtop. We wanted to move from the Nanodrops and Ocean Optics we were using previously to one stand-alone system that would meet the needs of both our Life Science and Chemistry programs. Less reagents, less waste, and no cuvettes are also big pluses for us. Simple for the undergraduate students to use, everything is touch screen on a stand-alone platform. No more benchtop computers and wires getting in the way on already crowded benchtops."

"The new version of the kinetics APP does not allow me to blank once and take measurement of multiple samples, which is critical to my workflow. However, this function is allowed in the previous version of the APP. We wonder if there is an option to downgrade the APP to an older version."

"Really easy to navigate, intuitive controls and quick response. The bench top size is just right. "

"Easy to use and pretty accurate. Super intuitive UI."

"The product was ready to use out of the box! That made it easy on me and I did not have to do any calibration! I would recommend buying this product."

"When implementing a new method, we struggled to determine best practices and appropriate settings for the machine. We were able to get in touch with one of their customer support technicians, Ben Capozzoli, and he was amazing! By far one of the best application specialists I have worked with, he is knowledgeable and offered us great insight into possible sources of error. Thanks to Ben, we were able to figure out a working protocol for our novel solution, and the machine is working as intended."

"The equipment demo was helpful and helped us finalize the decision to purchase. The equipment is easy to use and totally good value of money."

"Easy to use, fast reads for plasmid DNA, good linear dynamic range for high and low concentration samples, cuvette and fluorometer integration works well, don't love the touch screen but works okay, a lot of value compared to a new nanodrop."

"Our PCR technician loves this instrument, and it has held up to constant use in the last year. We just bought an additional one for another research lab. And, fire engine red!"

"This is a good machine! It can be adapted to work with a computer or a keyboard or just the touch screen depending on your comfort level with technology, and all of the applications come pre-loaded and ready-to-go. Connecting it to our site's server has been a little tricky, but for basic usage, it works well."

"I have been using this device for a about a year now. GFP worked great with the OD600 micro volume but this time we are having problems using it for TEVsh. Gave negative numbers and when called for help they only asked for a copy of the data to tell us that it did not work. Kind of disappointing. Other than that, it works great."

"The DeNovix instrument is easy to use and is a great product for the money."

"Good value for money, accurate measurement."

"The instrument is very user friendly and functions much like an android cellphone. I haven't yet used the wifi capability, but will be very soon and am looking forward to it.

"We are very happy with the new DeNovix machine. Easy to use, reliable and overall very helpful for everyday lab work."

"Very user friendly."

"Accurate and user friendly."

"We bought this unit after relying on another lab's machine from a competitor for far too long. It's a workhorse and having it WiFi enabled is great. It's been a hit since day one and the service from our vendor has always been super."

"This instrument is really very easy to use and easy to learn, clear and intuitive interface, quick response to commands without hanging. It also looks very modern and fits into other equipment in the laboratory. We hope that in the future it will delight with its impeccable work too."

"The instrument is great for people that have restricted lab space and do not wish to buy multiple instruments. I used the DS-11 FX+ for quantifying DNA and RNA, and to determine the turbidity of bacterial cultures. It worked great! For turbidity though, it didn’t work as well in the microvolume mode, but it was great using cuvettes. I haven't had the opportunity to use the fluorometer yet, only tested it with the kit that comes with the instrument, but it seems to work fine."

"Great stuff to work with. Gets a little bit trickier when working with genomic DNA. Going to try it with fluorescent labeling."

Android system make this instrument so cool like our mobiles. I have checked many RNA and DNA samples, results are reproducible with a small variation only."

"Our lab has recently purchased a DeNovix DS-11 spectrophotometer. I have used it for my miRNA quantification. It is a very simple and user friendly instrument. The best part is its sensitivity. It's a great value addition to our lab. The instrument has the android touch screen which makes it more user friendly and also trendy when compared to nanodrops from other companies. I think all labs should have this instrument."

"This instrument is very user friendly as it is coupled with android based applications. One can tap icons on the display and go ahead for quantification of DNA/RNA/Protein respectively. While performing tests, if you land on any errors, the instrument has an option to resolve the error on its own. This default setting ensures the user conducts their experiments without fear of ruining the instrument. We can save the data and retrieve it in excel format whenever it is required. This information saved in instrument can be mailed and develop the graphs for the same using other software available online. Or, you can just select the samples and tap of graph option which will develop the graphs on screen. These can be saved as JPEG screenshot and can be accessed. The accuracy and instant quantification makes this instrument a boon to researchers who struggle to get accurate and consistent results. The price of this instrument maybe costly but its worth having it."

"Very easy to use all-in-one product with simple operating methods. It's easy to use, stable and robust. It´s the best partner in the lab!"

"We really love the ability to get results by only using 1 microliter of liquid (1 microgram of protein) when before we had to waste at least 0.5 milligrams of protein ( 1 milliliter of liquid) to get absorbance results. It has saved us more times than we can count with quantitation of various liquid concentrations. We don't know how we survived before without it!"
