SmartDrop Nano Spectrophotometers
The Accuris SmartDrop series of nano spectrophotometers provides quick and easy quantification of small samples. Utilizing a small sample volume eliminates the need for dilutions, providing more accurate results. A full color, 7” touchscreen with icon-driven menus and preprogrammed protocols gets users up and running quickly. No external computer is required. Each unit features a quartz pedestal onto which a drop of sample is placed. The arm is lowered and the drop is stretched into a liquid column of specificed length for spectral analysis. DNA, RNA and protein concentrations and purity numbers are displayed in a matter of seconds.
The resulting data can be printed, saved in the SmartDrop’s onboard memory or exported via USB as an Excel file. All SmartDrop models include an integrated printer. For OD600 readings, each model includes a cuvette port and two optical glass cuvettes. Three SmartDrop models are available to meet a range of applications and budgets.
