S2100 Series Visible Spectrophotometer

The UNICO 2100 and 2100UV Spectrophotometers are fully flexible, easy-to-use and provide maximum performance expected from precise optics. The 2100 Series features an expandable sample compartment for up to 100 mm path length cells. Optional accessories include temperature control (Peltier or water bath), UNICO Application Software for Windows®.
The UNICO Model 2100 series are high performance, user-friendly UV/Vis spectrophotometers specially designed for the rigorous, day-to day demands of
today's laboratory. The state-of-art electronic design and high speed digital processing system guarantee users with fast and powerful data processing and reduce the noise to minimum. The rugged-constructed metal platform ensures durability and stability, unparalleled in the market
UNICO 2100 series adopt a sealed high-precision optical system design assuring a bandpass narrower than 5 nm and minimize the stray light. The measurement accuracy is maintained over the entire wavelength range.

The Unico S2100 Series Spectrophotometers are simple, flexible, easy-touse
and maximize value while providing performance you would expect for a
5nm bandpass instrument. The S2100 Series simplicity is reflected in its attractive
price without sacrificing accuracy and precision. The value is evident
from the performance provided every day, all year. The flat, low-profile design
minimizes bench “dead space”, allowing room for cuvette racks, notebooks
or a laptop computer. To simplify documentation, the S2100 Series
spectrophotometers can be controlled from UNICO® Application Software
for Windows® through the built-in RS-232C port. The standard software package
expands the applications to include standard curve, Kinetics (Abs. vs
Time) and the advanced software package further adds DNA/Protein analysis
and Scanning capabilities. Test data can be exported into Microsoft Excel®
for further analysis.
Easy-to-Use, Easy-to-Read Display
The two-line, LED display is large enough to read from any angle and distance, so there
is no need to search or “squint”. For UV models (S2100UV and S2100SUV), a simple
push of the button on the display panel allows you to turn on/off either lamp, extending
the lifetime. Readily switch modes from Absorbance to % Transmittance, or enter a
Concentration or Dilution Factor. No complicated menu to slow down technicians from
completing other important tasks. The standard large, flexible sample compartment has
a smooth 4-cell holder with 4 glass cuvettes and 2 quartz cuvettes (for UV models only)
included. A wide variety of accessories are available.
Four models to choose from:
S2100 Visible Spectrophotometer
S2100S Visible Scanning Spectrophotometer
S2100UV UV/Vis Spectrophotometer
S2100SUV UV/Vis Scanning Spectrophotometer
