UV-VIS DOUBLE BEAM SPECTROPHOTOMETER IG-28DS TOUCH

FEATURES & SPECIFICATIONS

DESCRIPTION:
The IG-28DS Touch spectrophotometer measures the amount of light that a sample absorbs by passing a light beam through it. These instruments are used to measure the concentration of any unknown solution and monitor absorption accuracy throughout production.

KEY FEATURES:

• • • Wide Wavelength Range: Covers a broad spectrum 190-1100 nm, meeting the needs of diverse industries.
    • Fully Automated Design: Simplifies measurements and ensures compliance with pharmacopoeia standards.
    • Upgradable Sample Capacity: Supports measurement of up to 8 samples simultaneously.
    • Automatic Lamp Switching: Seamless transition between Tungsten (T) lamp and Deuterium (D2) lamp for
      convenience
    • Advanced Optical System:
      Optimized optics and integrated circuits for precision.
      Light sources and detectors ensuring reliability.
    • Versatile Measurement Modes:
      Wavelength Scan
      Time Scan

      Multi-Order Derivative Determination
      Double Wavelength Method
      Triple Wavelength Method
    • Data Output Options:
      Printer port
      USB interface
      Data storage for easy access and record keeping.
    • PC Control Compatibility: Enables more accurate and flexible measurement operations through software
      integration.

  MEASUREMENT

  Basic Mode

  To measure the Absorbance and transmittance

  Quantitative Coefficient Method

  Standard Curve Up to 10 Standard sample may be used to establish a Curve. Four methods for fitting a curve through the calibration points: Linear fit, Linear fit through zero, Square fit and cubic fit.

  DNA/Protein Test

  • Concentration and DNA purity are quickly and easily calculated:
    Absorbance ratios 260 nm / 280 nm with optional subtracted absorbance at 320 nm.
  • DNA concentration = 62.9 × A260 − 36.0 × A280
  • Protein concentration = 1552 × A260 − 757.3 × A280

  Wavelength Scan

  • The wavelength scan intervals are 0.1, 0.2, 0.5, 1, 2, 5 nm.
  • High, medium and low scan speeds are available: 100 to 3600 nm/min.
  • Wavelengths are scanned from high to low so that the instrument
    waits at high wavelength and minimizes the degradation of UV-sensitive samples.

  STANDARD ACCESSORIES:

  • Glass Cell: 4 Nos
  • Quartz Cell: 2 Nos
  • Software
  • Instrument Cover
  • USB Cable
  • Software Manual
  • Instrument Manual
