SmartDrop™ XF Nano Spectrophotometers and Fluorometers

The Accuris™ SmartDrop™ XF Spectrophotometer and Fluorometer provide quick and easy quantification of small samples. Utilizing a small sample volume eliminates the need for dilutions, providing more accurate results. This top-of-the-line spectrophotometer can perform UV-Vis readings in the range of 200 nm - 800 nm and fluorescence readings. Like the SmartDrop X, the SmartDrop XF features predefined programs for nucleic acids, proteins, and various colorimetric assays. The patented, motorized system gently stretches the sample column and allows for three different path lengths, providing accurate readings of samples from 0.5 to 2.0 µL without dilution.

The integrated fluorometer yields more accurate, sensitive, and selective quantitation of nucleic acids. The blue light channel (460 nm) helps detect dyes such as PicoGreen and RiboGreen, as well as GFP and fluorescein. UV, green, and red channel models are available upon request. 

A full-color, 7-inch 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 sample drop is placed. The arm is lowered, and the drop is stretched into a liquid column of a specified length for spectral analysis. DNA, RNA, protein concentrations, and purity numbers are displayed in seconds.

The resulting data can be printed, saved in the SmartDrop's onboard memory, or exported via USB as an Excel file. An integrated printer is included. 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.
