NanoDropｮ ND-1000 Spectrophotometer Overview The NanoDropｮ ND-1000 UV-Vis Spectrophotometer enables highly accurate analyses of extremely small samples with remarkable reproducibility. The patented sample retention system eliminates the need for cuvettes and capillaries which decreases the measurement cycle time. In addition, the high absorbance capability eliminates the need for most dilutions. You値l find yourself making fewer dilutions and taking more readings than ever before, essentially becoming a more quantitative laboratory. Small samples: designed for 1-2 ul samples Hi absorbance capability: 50 times that of traditional spectrophotometers No Dilutions for most samples Full Spectrum (220-750nm) 10 second measurement time No cuvettes or capillaries Small size (size of a tissue box) Easy set up (plug and play) efficiency & quality Home [index.htm] About Us Links Contact Us Products Surface tension is used to hold a column of liquid sample in place while a measurement is made. This is done by pipeting the sample directly onto one measurement pedestal. A measurement column is then drawn between the ends of two optical fibers to establish the measurement path as shown below. The measurement is made, typically in less than 10 seconds, and the spectrum and its analysis is shown on the screen of the attached PC and archived on the PC. Once the measurement is complete, the sample is simply wiped from the measurement pedestals. The software enables individual user accounts for easy data segregation. The archived data can be manipulated by a spreadsheet program such as MS Excel. The ND-1000 offers many benefits over other spectrophotometers: Technology in Brief Technology in Brief ND-1000 Demo Video ND-1000 Specifications: Path length 1mm (with auto-ranging to 0.2mm) Sample size 1 microliter Lamp Xenon flash Detector Type 2048-element linear silicon CCD Wavelength range 220-750 nm Wavelength accuracy 1nm Wavelength resolution 3 nm (FWHM at Hg 546 nm) Absorbance Precision 0.003 absorbance (1mm path) Absorbance Range 0.02-75 (10mm equivalent absorbance) Detection Limit 2 ng/microliter (dsDNA) Max.

Analyses of quantification of nucleic acid, fluorescent dye, protein and cell cultures are all enabled with this software. Account Management Each user of the instrument can be assigned their own username and password which enables the user to specify their user preferences and allows for segregation of that user's archive files. The two initial accounts are "Default" and "Administrator". If the user does not log in, then the "Default" account settings are used. Archived Data The data from each measurement is automatically stored in the folder c:\nanodrop data in tab delimited format. The user can open the archive file using a spreadsheet program such as MS Excel. Utilities and Diagnostics Module This module enables troubleshooting of the instrument by generating a .jpg screen shot of a spectrum.
