DS-11 Series Spectrophotometer / Fluorometer by DeNovix

"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!"

"Extremely easy to use all-in-one product with simple operating methods and the most accurate DNA quantification I ever obtain in my entire reseach years!"

"Does everything well and easy for staff and students to use."

"This product is relatively easy to use. There are a couple of caveats. I like the Android system however I am an Android user. I could see an Apple user finding the interface confusing. It took us a little bit of trial and error to get the thumb drive working. Don't have a DYMO printer or a WIFI printer and setting up a networked printer seemed like a lot of work. The thumb drive export is perfect. It makes a .CSV file that opens easily and is easily manipulated in Excel. One thing to note is that only a FAT32 formatted drive will work. Rather than these couple of things the DS-11 is accurate and super fast two things we were missing in our cuvette spec."

Measures seem very precise and apps are frequently updated."

"This allowed us to quantitate protein faster (immediately rather than waiting 15 minutes for a colorimetric assay to develop) and using much less sample. We are now able to get more reproducible results and quantitate more often."

"Great product with high reproducibility. Very easy to use, can't find a alternate product for our application in this price range."

"It is very easy to use and the value for money is ok. After sales care was alright, we got a short "introductory lesson", so everybody is able and confident to use it."

"We brought this machine to replace the NanoDrop which is getting on for 10 years old. We use the machine to measure the amount of DNA extracted and the amount of DNA labelled when processing arrays. We've found the DeNovix to be more reliable, easier to use and better designed for the future than the NanoDrop. It also doesn't require for it to be linked up to a PC in order to work. However we still have to try to print the results from the DeNovix"
