Amersham Ultrospec 3100 Pro

Ultrospec™ 3100 pro is the ideal UV/visible spectrophotometer for the demanding laboratory where bench space is at a premium.

The Ultraspec 3100 pro's many features include stored protocols for protein determination (Bradford, Biuret, Lowry and BCA) and nucleic acid quantitation/characterization (DNA, RNA, oligonucleotide, theoretical Tm calculation). The Ultrospec™ 3100 pro has built-in application software designed to measure and calculate the incorporation of Cy3, Cy5, fluorescein, or other user-specified dyes into cDNA probes. This is essential information for optimizing the concentration of each labeled probe before use in microarray hybridizations.


UV/visible scans of each probe are displayed on the high-resolution display so that the integrity of the nucleic acid and fluorophore components of each probe can be inspected. Yield, fluorophore content, and efficiency of incorporation are automatically calculated and displayed when starting RNA concentration and dilution factors are entered. The software is particularly suitable for probes labeled with CyScribe™ fluorescent labeling kits.


An 8-position sample changer is supplied as standard and the instrument will print out to standard Centronics parallel printers and export results to a PC. With its extensive range of built-in software, a wide range of accessories (including a Sipper option) and GLP self-test diagnostics, Ultrospec 3100 pro is a reliable, compact and integrated system for use in any busy laboratory, including those which require data storage to a PC. Ultrospec 3100 pro can also be used in conjunction with SWIFT II Applications Software, if required.
