Benchmark Scientific NS1020 SmartDrop™ XF Nano Spectrophotometer, 115V

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.
