Description
The Accuris™ SmartDrop™ series of nano spectrophotometers provides quick and easy quantification of small samples. Using a microvolume sample eliminates the need for dilutions, providing more accurate results. A full-color 7-inch touch screen with icon-driven menus and preprogrammed protocols gets users up and running quickly, and no external computer or software is required.
The SmartDrop™ XF (NS1020) is the top-of-the-line model, performing UV-Vis readings from 200 to 800 nm as well as fluorescence readings. Like the SmartDrop™ X, it features predefined programs for nucleic acids, proteins and colorimetric assays. Its patented motorized system gently stretches the sample column and provides three path lengths (0.05, 0.2 and 1.0 mm), giving accurate readings of 0.5 to 2.0 µl samples up to 15,000 ng/µl dsDNA without dilution.
The integrated fluorometer yields more accurate, sensitive and selective quantitation of low-concentration nucleic acids. The blue channel (460 nm excitation) is suited to dyes such as PicoGreen and RiboGreen as well as GFP and fluorescein, with dsDNA sensitivity down to 0.5 pg/µl. It is designed for use with Accuris DNA and RNA quantification kits and 0.5 ml fluorescence detection tubes.
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 specified length for spectral analysis; DNA, RNA and protein concentrations and purity ratios are displayed in a matter of seconds. Results can be printed on the integrated printer, saved in onboard memory or exported by USB as an Excel file. For OD600 readings of bacterial cultures, every model includes a cuvette port and two optical glass cuvettes.
