Beckman Coulter DU 800 UV/Vis Spectrophotometer, Beckman Coulter 512902 With Pc Concentration Package Product Info
For life science, academia, biotech, and pharmaceutical applications. With a Windows*-based software interface, the DU 800 easily handles complex analyses and basic administrative functions. Software is designed to simplify daily analyses, including those regulated by the FDA, and fully supports compliance with FDA Regulation 21 CFR Part 11 (Electronic Records; Electronic Signature).
The integrated user interface of the DU 800 software provides convenient and useful featues such as quick access to system functions, continuous display of status and method parameters, and the ability to take quick readings or scans without exiting the current application. Spectrophotometer has many unique features including a source scheduler that can turn both the UV and visible lamp on and off independently at specified times each day; a performance validation scheduler that automatically warms up the system and then performs specified test(s) at a given date and time; and cell matching, which corrects for minor differences in multiple cells. Designed with a micro-focused beam, the DU 800 delivers the full energy of the beam to the microsample, unlike standard beams, which can lose as much as 80% of their energy when applied to a microvolume sample.
Transports are for automatic positioning and movement of samples in the unit. The standard transport is compatible with all ambient and water temperature regulated accessories. The high performance transport is compatible with all ambient and water or Peltier temperature regulated accessories. Note: The appropriate Peltier controller is required when electronic temperature control is desired.
Concentration Package Ideal for essential biological/analytical applications. Includes the DU 800, a single cell holder, and a 4.2mL UV silica cuvette, as well as DNA ratios (standard or user-defined). Can be used for kinetics/time studies and to plot standard curves for up to 30 standards.
Life Science Package For molecular biology and proteomic applications. Includes the DU 800, Protein Assay analysis application, Nucleic Acid Analysis II application, a single cell holder, a single cell holder for 50 L microcell, and two 50 L microcells. Features DNA ratios (standard or user-defined); DNA, RNA, and oligo quantitation; DNA theoretical melting point; and protein concentration with common assays.
Kinetics Package Designed for protein and advanced enzyme kinetics studies. Includes the DU 800, Enzyme Mechanism application, Protein Assay analysis application, standard transport, and Auto 6 cell holder (water-regulated). Use this package to perform characterization of enzyme reactions; calculate Km, Vmax, Kcat, and more; generate plots (such as Michaelis-Menten, Lineweaver-Burk); and conduct common protein assay methods.
High Performance Kinetics Package Has the same features as the kinetics package except instead of the standard transport it features a high performance transport, and the Auto 6 cell holder is Peltier temperature controlled.
All packages are available with an IBM PC and can integrate easily into a networked environment. The bundled PC is an IBM Net Vista with a 1.8GHz Pentium 4 processor, 128MB RAM, 40GB hard drive, integrated 38.1cm (15") TFT flat panel monitor, CD-ROM drive, and ethernet. The PC comes preinstalled with Windows 2000 and with all the included DU 800 system and applications software.
Minimum PC Requirements: Standard PC (266 MHz or faster), 128 MB RAM, available USB port, 31/2" floppy drive, CD-ROM drive, Microsoft Windows 2000, or XP.
Ordering Information: All packages come standard with Nucleic Acid Analysis (ratios), fixed wavelength, wavelength scan, kinetics/time, Single Component Analysis, and Performance Validation applications, as well as full support of 21 CFR Part 11.
