Spectro UV-VIS Double Beam
UV-Vis Double PC (Model UVD-2950) is a high performance
UV-Vis double beam automatic scanning spectrophotometer. It
is a two (2) cell spectrophotometer, now with a new and improved bandwidth of 1nm! . Model UVD-2950 spectrophotometer offers high performance,
ease of use and reliability, which can be used in various applications.
Spectrophotometer Model UVD-2950 can be used extensively for
qualitative and quantitative analysis in such fields as pharmaceutical
inspection, clinical analysis, petro-chemistry laboratories,
chemistry and biochemistry laboratories, DNA/RNA analysis as
well as in quality control departments, i.e. environmental control,
water management, food processing, and agriculture.
Spectro UV-Vis Double PC (Model UVD-2950) utilizes a
new optical system design and is microcomputer controlled. With
its focused-beam design, the system provides optimal and reproducible
results for small samples. The sample beam and the reference beam
are provided within the same sampling space which in turn facilitates
wider and longer scan of data providing a more detailed view of the results
in an easy to use environment. This instrument has excellent baseline
stability and high resolution and permits scanning, quantitative analysis,
kinetic spectrophotometric analysis and DNA/RNA analysis through PC control. This
product is capable of processing data, from analytical and spectrum testing.
Spectro UV-Vis Double PC (Model UVD-2950) has a large
LCD screen which displays the menu screen and of course makes the device
user friendly. Additionally, this instrument has a powerful built-in
software which permits the apparatus to be linked to a computer and
a printer to display the photometric and spectral data on the PC monitor.
Labomed, Inc. is certified by ISO 9001-2000, has CE Conformity and is FDA Licensed. Spectro
UV-Vis Double PC (Model UVD-2950) with fixed bandwidth
of 1 nm is a high-performance, reliable, and exceptional value instrument
which is the hallmark of Labomed UV-Vis spectrophotometers.
This Spectro can be used by itself or linked to a PC.
