SPE4004

The Accuris SmartDrop™ series of nano spectrophotometers provides quick and easy quantification of small samples. Utilising a small sample volume eliminates the need for dilutions, providing more accurate results.

A full color, 7” touchscreen with icon-driven menus and pre-programmed 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 specified 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.

A full spectrum UV-Vis spectrophotometer, SmartDrop X requires 0.5 to 2.0µl of sample. In addition to nucleic acid and protein calculations, the software has preset programs for BCA, Bradford and Lowry assays. A full spectrum analysis can be performed in about 6 seconds, aiding in the identification of unknowns. Up to 5 specific points on the spectrum can be selected for colorimetric readings output. The long life Xenon lamp source requires no warm up and is paried with a highly sensitive CCD detector. To provide the most accurate results, the SmartDrop X utilizes 2 path lengths.
