LIUV 201 Scanning UV Visible Spectrophotometer.  Click here for LIUV 210 pdf brochure download

   LIUV-201 is a stand-alone model with 2nm fixed bandwidth. It features high performance sealed optics mounted on a stable machined platform. The innovative optical layout and state of art monochromator with high grade blazed holographic grating ensure accuracy. Its integrated design assures long term stability and durability. The precisely aligned detector and quality deuterium and halogen lamps enhance the precision across the UV/Vis spectrum starting from 190nm and into the near-infrared (NIR) 1100nm. The comprehensive features, sophisticated powerful software, variety of accessories and model configurations will meet or exceed your expectations for performance and value.

It has a large angled LCD screen with contrast adjustment for comfort viewing. The large sample compartment accommodates a wide range of cell holders and accessories including peristaltic sipper and a Peltier system. Optional Windows post-run application software make this instrument very versatile.

The standard stand alone operation of the system allows the following functions to be easily accessed from the LCD screen.

1. Basic mode  Absorbance, Transmission or Concentration measurements with entry of a wide range of units.  

2. Quantitative Establish or use stored calibration equation to measure the concentration of unknowns. Up to 10 standards can be used and 4 different Curve fitting models are supported with three different Quantitation modes. 

3. WL scan Spectrum scan of sample at any selected wavelength range with choice of scanning speed and wavelength interval. The wavelength scan intervals are 0.1, 0.2, 0.5, 1, 2, 5nm, and Hi, Medium and Low scan speeds are available. Scan speeds vary from 100 to1000 nm/min. Wavelengths are scanned from high to low so that the instrument waits at high wavelength. This minimizes the degradation of UV sensitive samples. Precise control of filter and lamp changes means that their effects are not seen on the final scan. Postrun manipulation includes re-scaling axes, curve tracking and peak picking.

4. Kinetics Measurement of absorbance changing vs. time with reaction rate calculation function. This mode may be used for time course scanning or reaction rate calculations. Abs. vs. time graphs are displayed on the screen in real time. Wait time and measurement time up to 12 hours may be entered with time intervals of 0.5, 1, 2, 5, 10, 30 secs and 1 min. Post-run manipulation includes rescaling, 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 .  

5. DNA/Protein Calculation of concentration and DNA purity. Ratio at other wavelengths can be measured. Concentration and DNA purity are calculated as Absorbance ratios 260nm/280nm or 260nm/230nm, with optional subtracted absorbance at 320nm

6. Multi Wavelength Measurement at multiple wavelengths to analyse and determine the composition of the mixtures. Up to 10 wavelengths may be entered, allowing the measurement of multiple wavelengths on a series of samples.

7. Utility - GLP Utility programs offer wavelength and photometric accuracy validation for GLP compliance. It contains useful programs and tools such as reset dark current, reset lamp change-over wave-length, lamp usage set, set clock, etc. for the GLP compliant laboratory LIUV-201 spectrophotometer may be automatically self-calibrated on switch-on, using the 656.1nm deuterium emission line. This function may be repeated at any time. The wavelength accuracy may be checked using the “WL Validity” program (wavelength calibration standards required). The absorbance accuracy at several wavelengths may be checked using the “Accu Validity” program.

8. Defined Test This is an open platform for user defined programs.

Additional Optional software is available at extra cost to connect the LIUV 201 to a computer for more sophisiticated data processing and LIMS connection.

LIVI-300 Visible Spectrophotometer is single beam, general purpose instrument designed to meet the needs of the laboratories for analysis. It is ideal for various application fields such as, chemistry, medicine, environmental protection, food and beverage, wine industry and quality control.  It is ideal for student lab use as it is robust and easy to use. It offers 325 to 1000nm wavelength range and optional Windows software. The LIVI-300  windows-based software runs on a PC with 95/98/Me/XP operating systems. The software offers two additional analytical methods: 

Standard Curve and Absorbance vs.Time Kinetics.  It operates in the following three modes:

Absorbance /% transmittance/Concentrations: Measures absorbance at a given wavelength within the range of 325 -1000 nm.

Standard Curve: Creates a calibration curve (choice of 4 curve fits) with up to 8 standard solutions at a given

Absorbance vs. Time Kinetics: Measures a sample’s absorbance change over a period of time, store the test results, display
