Life Science Applications
  • Nucleic Acid concentration by direct UV measurement at 260nm including DNA, ssDNA, RNA, and siRNA

    Nucleic acid purity measurements from 260/280nm and 260/230 ratios

    Protein analysis by direct UV measurement at 205 or 280nm

    Measuring the fluorescence labeling efficiency for proteins and nucleic acids

  • Oligo calculator tool for calculating nucleic acid properties including melting points

Analyzer mode

  • Create a dedicated workflow program to guide technicians through even the most complex assays with the touch of a button
  • Customized User Environment software (CUE) uses simple, step-by-step, flowchart-like tools to program complete multi-step analyses for future use Program allows user to format screen displayed with method when it is executed
Color Touchscreen
  • Use a stylus pen or a mouse and keyboard connected directly to the instrument to navigate the screen
  • A complete line of sample changers, temperature control and monitoring accessories, fiber optic probe systems, and tools for measuring reflectance and transmission of solid samples
Double Beam Geometry
  • Taking the ratio of the sample to the reference beam at each data point negates the effects of changing samples—especially useful for kinetics, long-term process monitoring, and difficult samples
Focused Beam Optical Design
  • Uses a highly focused sample beam to get the best performance from microcells
  • Allows more than 80% of the light beam to pass through the 2 x 2mm aperture of a 40µL microcell
  • Provides maximum light throughput for use with fiber optic accessories and microcells from 40 to 500µL without the need for masked cell holders or cuvets
Mono Drive
  • Precision monochromator drive delivers fast scanning data collection and wavelength accuracy
Xenon Flash Lamp
  • Low cost of ownership, longer time between maintenance cycles, high intensity in the UV and visible regions of the spectrum
  • Xenon lamps require no warm-up time for instant measurements
Trigger Connections
  • Electronic triggering provides the highest level of accuracy for rapid-mixing kinetics measurements
System Validation
  • The UV Validator streamlines Installation Qualification (IQ), Operational Qualification (OQ) and performance Qualification (PQ) procedures for simple and efficient use by the end user
Security Software
  • If your laboratory requires 21 CFR Part 11 compliance, Thermo Scientific INSIGHT security software is here to make your life easier
