Product Description

UV-2400PC and UV-2100PC Single Beam Ultraviolet Visible Spectrophotometer

UNICOM-OPTICS UV-2400PC and UV-2100PC feature high performance sealed optics mounted on a stable machined platform. The innovative optical layout and state of C-T 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 200nm and into the near-infrared (NIR) 1000nm. All spectrophotometer are intended to be utilized for research, development, quality control, etc. primarily in the fields of optical materials, semiconductors, new materials, electronics and so on through qualitative and quantitative analyses of samples diverse in kind and size. The comprehensive features, sophisticated powerful software, variety of accessories and model configurations will meet or exceed your expectations for performance and value.

Full CE compliance


Features for Windows®-Based Application Software


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.
