SmartDrop™ X - Nano Spectrophotometer
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.
- Full-spectrum absorbance scans from 200 to 800nm
- Quickly calculates and displays 260/280 and 260/230 ratios
- Long-life Xenon lamp with precision monochromator
- Auto-ranging path lengths of 0.2mm and 1.0mm
- Detect up to 4,500 ng/µl of dsDNA without dilution
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 paired with a highly sensitive CCD detector. To provide the most accurate results, the SmartDrop X utilizes 2 path lengths.
