The SmartDrop™ series of nano spectrophotometers provides quick and easy quantification of small samples.

• 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 0.05, 0.2 and 1.0 mm
• Detect up to 15000 ng/µl of dsDNA without dilution
• Integrated fluorometer for sensitive quantitation of low concentration nucleic acids

These spectrophotometers utilize a small sample volume which eliminates the need for dilutions, providing more accurate results. Each unit includes a full color, 7"
touchscreen with icon-driven menus and preprogrammed protocols gets users up and running quickly. No external computer is required.

This top of the line spectrophotometer can perform not only UV-Vis readings in the range of 200-800 nm 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 2.0 µl without dilution. The integrated fluorometer yields more accurate, sensitive and selective quantitation of nucleic acids. The blue light channel (460 nm) 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.

Units feature 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.
