SmartDrop XF – Spectrophotometer + Fluorometer
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 scanning and calculations of 260/280 and 260/230 ratios
- Long-life Xenon lamp with precision monochromator
- Auto-ranging path lengths of 0.05mm, 0.2mm and 1.0mm
- Detect up to 15,000ng/µl of dsDNA without dilution
- Integrated fluorometer for sensitive quantitation of low concentration nucleic acids
This top of the line spectrophotometer can perform not only UV-Vis readings in the range of 200-800nm but also 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 2.0µl without dilution.
The integrated fluorometer yields more accurate, sensitive and selective quantitation of nucleic acids. The blue light channel (460nm) is useful for detection of dyes such as PicoGreen and RiboGreen as well as GFP and fluorescein. UV, green and red channel models are available upon
request.
