SmartDrop L
• Ideal for basic DNA/RNA/protein quantification and purity
• Affordable LED and silicon detector technology
• Fixed 0.5 mm path length, detect up to 2,500 ng/µL of dsDNA
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 280 nm. Samples from 1.0 to 2.0 µL are loaded directly on the pedestal. Results are provided in about 5 seconds. The software automatically calculates and displays 260/280 ratios.
SmartDrop X
• Full-spectrum absorbance scans from 200 to 800 nm
• Quickly calculates and displays 260/280 and 260/230 ratios
• Long-life Xenon lamp with precision monochromator
• Auto-ranging path lengths of 0.2 mm and 1.0 mm
• Detect up to 4,500 ng/µL of dsDNA without dilution
A full-spectrum UV-Vis spectrophotometer, SmartDrop X requires 0.5 to 2.0 µL 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 five specific points on the spectrum can be selected for colorimetric reading 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 two path lengths.
SmartDrop XF – Spectrophotometer + Fluorometer
• 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 mm, 0.2 mm, and 1.0 mm
• Detect up to 15,000 ng/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 200–800 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.
