4120025 Visible range spectrophotometers

APPLICATIONS
They are widely used in colleges and enterprises for general quantitatives analysis and experiments based in absorbance measurements.

COMMON FEATURES
Highquality siliconphotometricdiodedetectorand1200lines/mm diffraction grating ensure the high quality accuracy and precision. Digital display for an easy readout. 
Automatic zero and blank (easy to use). 
Easy switching of transmittance, ab- sorbance and concentration modes, just by pressing one key. 
Large sample compartment, whichcanaccommodate5to100mm pathlength cuvettes with optional holders. 
Its pre-aligned design makes it possible to change the halogen lamps by the user himself.

Optional: 
Optional software based on Windows® which can expand the applications to standardcCurve and kinetics.

V-1100 MODEL 
Easy of use. 
Ergonomic and solid design for a continuous suitable use, for students and workers.

VR-2000 MODEL 
Large LCD screen (128x64bits). 
It can display a total of 50 groups of data (3 groups per screen). 
It can display standard curve and kinetics curve graphic. 
The system can also save the test results. 
Atotal of50datagroups and10standardcurves canbe savedinthe RAM me- mory. 
At most 9 standard samples can be used to establish a standard curve. 
The curve andthe curve equation willbedisplayedsimultaneously onthe scre- en.
The unknown concentration solutions, can be measured by the curve. 
Ifoneknows thecoefficientkand b of theformula: C=kA+b,onecaninput the value directly. 
Data is stored in the memory in case of power cut.
