  All spectrophotometers feature high performance sealed optics mounted on a stable machined platform.  All spectrophotometer are intended to be utilized for research, development, quality control, etc. primarily in the fields of optical materials, semiconductors, new materials, electronics and so on through qualitative and quantitative analyses of samples diverse in kind and size. The comprehensive features, optional sophisticated powerful software, variety of accessories and model configurations will meet or exceed your expectations for performance and value.

  The spectrophotometers perform built-in wavelength calibration program automatically after energization. Core components will be check during the initialization to ensure the wavelength accuracy and excellent performance

  Pre-aligned deuterium lamp and tungsten lamp for easy lamp replacement. The light source changing point can be set in range of 300nm - 400nm

  The innovative optical layout ensures accuracy. Its integrated design assures long-term stability and durability. The precisely aligned detector and quality deuterium and halogen lamps enhance the precision.

  Perform basic mode( Abs / %T), quantitative

  Pre-set wavelength program (4 wavelengths), and one-touch key response

  Single-point curve calibration and multi-point curve calibration (up to 12 points)

  Display of fitting degree of curve fitting and concentration data with up to 50 sets of curve parameters storage

  Display of concentration data with up to 200 sets of data storage

  Dark current calibration / wavelength calibration/System clock management

  Backup battery and integrated circuit design controlled by MCU assure non-volatile memory storage

  USB data communication

  LPT port for printing

  128*64 LCD screen to display all of the parameters

  Sealed and solvent-resistant tactile keypad

  Basic Mode		Multi-Wavelength
  Absorbance, %T or Concentration measurements.		Up to 15 wavelengths can be selected and multiple samples can be measured. (Auto cell changer is required to run multiple samples automatically).
  Quantitative (Standard Curve) Use up to 12 standards to establish standard curve. Four methods for fitting a curve: a. Linear fit b. Linear through zero c. Square fit d. Segmented		Wavelength Scanning Interval: 0.1, 0.2, 0.5, 1, 2, 5 nm Automatically record peaks and valleys. Post-run manipulation and processing includes: a. Re-scaling axes, curve b. Smoothing, combination, zooming, overlap c. 1st to 3rd derivative
  Kinetics (Abs vs. Time) The Kinetics mode may be used for time course scanning or reaction rate calculations. Abs. vs. time graphs is displayed on the screen in real time. Wait time, measurement time and time intervals may be entered. Post-run manipulation includes re-scaling, curve tracking and selection of the part of the curve required for the rate calculation. Rate is calculated using a linear regression algorithm before multiplying by the entered factor.
  DNA/Protein Concentration and DNA purity can be calculated quickly and easily: Absorbance ratios 230nm/260nm/280nm with optional subtracted absorbance at 320nm.
