The UV/V12 spectrophotometer have the most attractive cost performance.
Using your standard sample solutions, you can get a standard curve on the large
LCD screen by the local control software, also you can print the curve through
the parallel port. They are widely used in colleges and enterprises for general
quantitative analysis and experiments.

SPECTRO-UV3 Series is an advanced single beam design consisting of 10
models. They differ In bandwidth & wavelength accuracy, but provide excellent
performance for measurements in the range of 190nm to 1100nm. Optional
add: S to spectro UV 32 selectable bandwidth 0.5,1,2,4nm. They are suitable
for clinical lab applications, pharmaceutical, & bio-chemical. as well as routine
applications such as Quantitative analysis, Kinetics, Wavelength Scan, Multi-
Wavelength, & DNA/Protein analysis. UV-Vis Analyst application software based
Microsoft Windows makes these instruments versatile. All instruments provide
excellent performance for measurements. They are divided into in 2 types: PC
models & stand-atone models -In Stand-alone models, all software methods are

2. Quantitative
I)
Standard Curve
At most 9 standard samples can be used to establish a standard curve, the curve and the
curve equation will display on the screen simultaneously. You can measure your unknown concentration solutions by the
curve. II)
Coefficient Method
If you have known the coefficient k&b of the formula C=kA+b, you can input the value directly
by the button,Then to test your unknown solutions.
