Product Description

UV-4100PC and UV-3100PC Double Beam Ultraviolet Visible Spectrophotometer

Unicom-Optics UV-4100PC and UV-3100PC Double Beam UV/VIS Spectrophotometers can meet the broad requirements of pharmaceutical, biochemical and clinical lab applications as well as routine applications such as quantitative analyses, kinetics, spectrum scanning, multiple components and DNA/Protein.

UV-4100PC and UV-3100PC Double Beam UV/VIS Spectrophotometers must link with PC. (PC not included).

The two detectors are measuring sample and reference respectively and simultaneously for optimizing measurement accuracy. It provides excellent performance for measurements in the range of 190nm to 1100nm. It is suitable for pharmaceutical, biochemical and clinical lab applications as well as routine applications such as quantitative analyses, kinetics, spectrum scanning, multiple components and DNA/Protein. PC Windows® application software makes this instrument versatile.

Basic Mode

 

Abs/%T/Con Test.

 

Quantitative (Standard Curve)

 

Use up to 32 standards to establish standard curve.

Four methods for fitting a curve:

1. Linear fit

2. Linear through zero

3. Square fit

4. Segmented

 

 

Wavelength Scanning

 

Automatically record peaks and valleys.

Post-run manipulation and processing includes:

1. Re-scaling axes, curve

2. Smoothing, combination, zooming, overlap…

3. 1st to 4th derivative

 

 

 

Time scanning

 

Abs. vs. time graphs is displayed on the screen in real time. Wait time, measurement time and time intervals may be entered. Post-run manipulation includes re-scaling, 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.
