SmartDrop Nano Spectrophotometers for Microvolume Analysis of DNA, RNA and Proteins
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.
The SmartDrop Nano Spectrophotometers offer:
Quick and accurate results from a sample droplet
Touch screen control panel, no PC or software required
Built-in printer and cuvette port for OD600 readings
XF model includes fluorometer for sensitive DNA
quantification
SmartDrop L
SmartDrop L is the affordable choice for laboratories needing to determine nucleic acid and protein concentrations and purity of samples. The LED light source and silicon photocell sensor provide readings at 260 and 280nm. Samples from 1.0 to 2.0µl are loaded directly on the pedestal. Results are provided in about 5 seconds. The software automatically calculates and displays 260/280 ratios.
Ideal for basic DNA/RNA/protein quantification and purity
Affordable LED and silicon detector technology
Fixed 0.5mm path length, detect up to 2500ng/µl of dsDNA
SmartDrop X
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.
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
SmartDrop XF – Spectrophotometer + Fluorometer
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.

Accuris DNA Quantification Kits
Accuris DNA Quantification Kits are designed for accurate fluorescent quantification of dsDNA using instruments such as the Qubit®, SmartDrop™ XF, and microplate readers. The reagents are highly selective for double-stranded DNA (dsDNA); quantification results will not be skewed by single-stranded DNA (ssDNA), RNA, protein, or nucleotides in a sample. Included with each kit are a concentrated fluorescent assay reagent, dilution buffer, and ready-to-use DNA standards. The assay reagent is diluted using the buffer provided, sample is added (1 µL to 20 µL), and the concentration determined using an appropriate fluorometer instrument that utilizes blue excitation (460 ± 20 nm) and measures green fluorescence (525-570 nm).
High Sensitivity dsDNA Assay Kit
The Accuris High Sensitivity Kit provides an accurate method to quantify low concentration dsDNA samples. The assay kit is designed to be accurate for initial DNA sample concentrations of 0.005–120 ng/µl, providing a detection range of 0.1–120 ng.
Broad Range dsDNA Assay Kit
The Accuris Broad Range Kit provides an accurate method to quantify dsDNA samples that have a broad concentration range starting at 0.2 ng/µL. The assay kit is designed to be accurate for initial DNA sample concentrations of 0.2 to 2,000 ng/µL, providing a detection range of 4−2,000 ng.
