Implen’s Overcoming 21 CFR Part 11 Limitations of Other Technologies
Have you experienced any of these difficulties finding the right technology?
- No user management/21 CFR part 11 compliant software available
- User management/21 CFR part 11 compliant software only available via external computer (no stand alone option)
- No REST API interface available to connect to your LIMS System
- Complex and pricy IQOQ procedures only offered with an expensive contract for onsite service
- Long measurement times
- Cumbersome software user interface
- Costly recalibration/maintenance or decreasing accuracy over time
- Instrument’s service and support discontinued and software not compatible with Windows10 or Mac OS
- Low reproducibility (mainly caused by evaporation effects)
- Getting results for more than 40 samples per run is time consuming
- Waited for weeks to get instrument repaired
How about trying a device that overcomes all of these 21 CFR issues?
Implen NanoPhotometers® Reviews
“Excellent design and is easy to use“
Rating: 5.0 ★★★★★
Application Area: Neurosciences
“The photometer has excellent design, and is easy to use. Built-in vortex is one of the smartest decisions I’ve seen in lab equipment. Data manipulaton and interface decrease hand-on time, and are user-friendly.”
Olga Starkina

“Really impressed with the accuracy, ease of use, and increased sample throughput“
Rating: 5.0 ★★★★★
Application Area: DNA Analysis
“I’ve really been impressed with the accuracy, ease of use, and increased sample throughput with this instrument. All this in such a small and sleek black box. The touch screen interface is a nice feature and very straightforward. You can easily navigate through the applications, load templates, access and analyze your data. I like that you’re given the option to run up to 12 samples at a time but you can also choose to run 1 or 2 samples, customizable to your experiments. Having options is always a plus and you get that with the N120. The pipette guide makes it really easy to apply your samples. I can see that a lot of time, expertise, and careful considerations went into developing the NanoPhotometer.”

“Accurate Measurements, Solid Device“
Rating: 5.0 ★★★★★
Application Area: DNA Concentration Quantification
“My lab does a lot of molecular cloning work for synthetic biology projects. For the longest time we didn’t have any reliable and simple way of quantifying DNA concentration. This device has been a a life saver. It is accurate (checked samples against other similar devices), easy to use, has lots of extra features that the competitors lack and is cheaper.
If you are just needing to quantify DNA concentration the N50 is a solid choice. But it comes with so many other features you’ll be left wondering how other manufacturers get away with charging more for less. Overall the device is very sturdy and produces accurate results. But beyond just the basics you can do protein and kinetics assays and more. The touchscreen is easy an intuitive. Results are saved directly to the machine as a pdf or spreadsheet and can be retrieved remotely by a tablet/phone or a desktop computer. I prefer to simply copy the pdf directly to my laptop over the network. Another great feature is that the sample pedestal has a visible light shining through it while you load the sample which makes it easier to see what you’re doing. That is something I have not seen on any other microvolume spectrophotometer. My only complaint, if I have to come up with one, is that typing on the touchscreen with my arm extended out in front of my is kind of clumsy. But its a minor inconvenience. I just stick to short samples names.”

“Best small volume spec on the market“
Rating: 5.0 ★★★★★
Application Area: Protein/nucleic acid quantitation
“The Implen NanoPhotometer N50 is extremely easy to use (intuitive menus and settings), accurate, and genuinely capable of measuring very small volumes repeatably. The touch screen works well even with gloves. Window configurations are adaptable so you can customize the information you’re looking at while working. The instrument is light and mobile, and since it’s all-in-one, you can literally move it to where you’re working as needed. It’s not stuck in a particular corner of the lab. In my opinion, it’s the best nano-scale measurement device on the market for routine lab sample quantification and spectral reading.”
David Rawling
Organization: Inflammatix, Inc., USA
“Easy use and accurate results “
Rating: 4.7 ★★★★★
“We are using it for nucleic acid quantification. It’s so easy to use, gives accurate results and easy to save data in organized way. Would recommend it.”
