Product description

The DeNovix DS-11 takes spectrophotometry to a whole new level. This easy-to-use, compact instrument delivers full spectrum UV-Vis analysis and is ideal for rapid nucleic acid and protein quantification. Simply pipette and measure. It’s that easy.

Intuitive and Easy. DS-11 Spectrophotometers are simple to use and fast to learn thanks to DeNovix EasyApps®. The software is pre-installed on a breakthrough AndroidTM operating system that features an HD, glove-compatible touchscreen. No PC set-up or software installation is required!

SmartPath® Technology is our patent pending design to precisely control microvolume pathlength in real-time. SmartPath® ensures the DS-11 is always in calibration – no drift and no service down-time. Measurements are accurate and precise for 1µL , even for difficult to measure samples like protein.

DS-11+ Cuvette Mode enables up to 10mm pathlength measurements using standard quartz or disposable cuvettes extending the UV-Vis lower detectible limit. The built-in cuvette heater controls temperatures for Kinetics studies.

Connect to Your Results. Built-in Wi-Fi, Ethernet and USB allows easy export of data you want in the format you need. Email a csv or color jpg of your results…save data to LIMS or network drives…print results or graphs to network and label printers…and more!
