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, sophisti-

cated 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 sipper and Peltier system. Optional Win-

dows post-run application software makes this instrument very versatile.

Easy to Operate Local Control Software

All software methods are built-in as standard, thus eliminat-ing the need for software options. Through the control panel, user’s can perform all operations by pressing the keys and all the results and operation infor-mation are displayed on the LCD

2. Quantitative

Establish or use stored calibration equation to measure the concentration of unknowns.

3. WL scan

Spectrum scan of sample at any selected wave-length range with choice of scanning speed and wavelength interval.

4. Kinetics

Measurement of absorb-ance changing vs. time with reaction rate calcu-lation function.

5. DNA/Protein
