Spectro
UV-Vis Split
Beam PC (Model UVS-2800) is a precise scanning
spectrophotometer with a new design of an eight (8) automatic microprocessor
with 2 row cell holder for precision testing and noiseless movement.
This Split Beam Spectro has a variable bandwidth ranging from 0.5,
1.0, 2.0 and 5.0 nm. and a dual detector, which in turn makes it
an extremely accurate system. This spectrophotometer has
a large LCD display, which can function independently, or,
in the alternative it can be linked to a computer and a printer. With
the RS-232C, the port, and the included software, the instrument
can be linked to a computer, which is compatible with Windows Platforms,
and a printer to display the photometric and spectral data on the
PC monitor.
Spectro UV-Vis Split Beam PC (Model UVS-2800) offers
high performance, ease of use and reliability, which can be used
in various applications. Spectrophotometer Model UVS-2800 can be
used extensively for qualitative and quantitative analysis in such
fields as pharmaceutical laboratory, agricultural laboratory, research
industry, inspection, clinical analysis, petrochemistry laboratory,
chemistry and biochemistry laboratories, DNA/RNA analysis as well
as in quality control departments, i.e. environmental control, water
management, and food processing.
Spectro UV-Vis Split Beam PC (Model UVS-2800) is also
capable of performing kinetic test through the use of an optional Peltier
Constant Temperature System. Additionally, this instrument can
analyze flow through liquid with the use of the optional Sipper Flow
through System. Further, this spectrophotometer is capable of
performing DNA/RNA measurement and printing its result through the
use of an external HP 600/800 series printer.
Labomed, Inc. is certified by
ISO 9001-2000, has CE Conformity and is FDA Licensed.
Spectro UV-Vis Split Beam PC (Model UVS-2800) with variable
bandwidth of 0.5, to 5.0 nm is a high-performance, reliable, and
exceptional value instrument
which is the hallmark of Labomed UV-Vis spectrophotometers.
There are 2 models of Spectro UV-VIS Double PC 8 Auto Cell available
to the public:
1) Spectro UV-Vis Split Beam PC (UVS-2700) has fixed bandwidth
of 2 nm.
2) Spectro UV-Vis Split Beam PC (UVS-2800)
has variable bandwidth of 0.5 to 5.0 nm
